iPhone Antenna Repair

iPhone 5 Antenna Replacement Toronto MississaugaThe antenna is a component that allows your iPhone to connect to your carrier’s cellular and LTE network. If you drop your phone or it gets somethign spilled on it, the antenna can get damaged. The antenna cable can break or disconnect from the logic board, creating a problem with the signal.

If people you call complain that you are “cutting out”, or you find that you only have 1-2 bars beside the carrier’s name, or the dreadful “No Service” message – you should bring your iPhone to one of our locations in Toronto or Mississauga to get your cellular antenna replaced.

Our trained technicians can do the antenna replacement on your iPhone within an hour, while you enjoy a coffee and Netflix in our lounge!

It can be frustrating to have a phone with a damaged or malfunctioning antenna, because the antenna controls many of the functions that make cell phones such an important part of many people’s lives. Simple tasks such as making and receiving phone calls, sending text messages or using your cell phone service provider’s LTE network suddenly become annoying or impossible when your cell phone has a broken or damaged antenna cable.

The antenna cable in the iPhone is connected to the rest of the internal “guts” of the phone, which is called the logic board, and if the connection holding the antenna to the logic board becomes damaged or broken, you might experience issues such as:

-dropped calls,

-calls where the person on the other side of the call complains you are cutting out,

-a “No Service” or “Emergency Service Only” message where the signal strength bars should be,

-only 1 or 2 signal strength bars filled instead of 4 or 5, or

-you are unable to connect to LTE or 3G networks.

iPhone 4 Camera Replacement Toronto MississaugaYour iPhone back camera needs to be replaced when:

  • You open the camera app and the “shutter” doesn’t open;
  • You open the camera app and the screen is black;
  • Your camera is blurry;
  • Your camera lens or glass is cracked or scratched;
  • Your camera has dark spots or other problems with the image.

If you are experiencing any of the above issues – bring it in and our skilled technicians will replace your iPhone main camera in about an hour, so you can get back to taking photos of your breakfast and sharing them with your friends!

Camera phones have made taking photos and sharing them with friends, family or even the entire Internet easy, quick and fun. For some iphone users, the quality of the camera on the back of their phone is a major part of their decision-making process when thinking about buying a new cell phone. Capturing the perfect moment is important to a lot of people, so why waste time using a cell phone with a broken camera? Bring it to the TechKnow Space and within one hour we can fix or replace your damaged iphone back camera.

Apple is constantly releasing new camera technology that promises to push iPhone photography to levels few have experienced. The iPhone 7 Plus for example features both an f/1.8, 28mm wide-angle lens and a 56mm telephoto lens on the back. A lens is only as good as the sensor and processing pipeline behind it. The iPhone 7 sports a 12-megapixel sensor behind its 28mm wide-angle lens, while the iPhone 7 Plus packs another 12-megapixel sensor behind that portrait-friendly telephoto lens. These modules are optically stabilized, which minimizes the blurriness of photos shot with shaky hands.

Look Sharp: The killer app on the 7 Plus is a 2x optical zoom. Tap an onscreen button to jump from the wide angle to the telephoto lens. Yes, all smartphone cameras let you zoom, but most of them use a digital zoom. That means the lens doesn’t move, the camera merely enlarges the pixels in each photo for a bigger view. Such images degrade as you increase the zoom. The new iPhone has digital zoom too, but because you’re starting with 56mm telephoto glass, you’ll see less degradation in resolution as you start moving in with the 10x digital zoom. Apple also touts the expanded dynamic range and color capabilities of the new shooter, and a RAW mode saves images in DNG format—a feature common to higher-end cameras, but absent from most phones.

Processing Power: In both the single-shooter iPhone 7 and the dual-lens iPhone 7 Plus, Apple claims this processor uses machine learning to scan a scene for faces and other recognizable objects, then pays particular attention to them when focusing and setting exposure. It also optimizes everything from the white balance to noise reduction to tone mapping

Many users and consumer reviews have agreed the iPhone 6 and iPhone 6+ has a greatly improved camera, compared to previous versions of the iPhone. The camera itself is still the same 8 megapixel camera that has been a staple of all iPhones since the iPhone 4S, but the software supporting the camera in the iPhone 6 and iPhone 6 Plus has been significantly upgraded. Apple has added “Focus Pixels,” which are meant to focus the camera on the intended subject faster and more clearly. This should allow iPhone 6 and iPhone 6+ users to get the photo they are hoping for on the first try, and also spend less time fussing with camera settings before snapping a picture. These pixels, in addition to focusing better, allow for manual exposure settings and better face and blink detection. Another function added to the rear camera on the iPhone 6 and 6 Plus is a second option when in slow-motion video mode, giving the user the option of slowing down high-speed action even further than the iPhone 5/5S/5C is capable of managing.

iPhone 6 Front Camera Replacement Toronto Mississauga

iPhone Bluetooth Repair

iPhone 6 and 6 Plus Bluetooth Repair Toronto Mississauga

Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices, and building personal area networks (PANs).

Bluetooth is an effective way of connecting your cell phone wirelessly to a wide variety of devices such as:

  • Hands-free headsets
  • Car stereo or GPS systems
  • Wireless headphones or speakers
  • Wireless keyboards
  • Home security devices such as locks or alarms
  • Other mobile devices like laptops, tablets or cell phones
  • And many other applications.

This cordless technology works using radio waves like an FM radio transmitter would, but instead of the signal travelling hundreds or thousands of kilometers to your radio or phone or TV, the radio waves only need to travel a short distance, usually a minimum of 10 metres, but can be stretched to more than 100 metres. This might seem like a limitation, but it is actually a good thing, as it keeps the power usage of the device low.

Enabled media devices use these waves to connect through constantly refreshing networks called “piconets”. Devices connected to one another are a “pairing”, or are “paired”.

These networks are kind of like rubber bands. Devices are automatically connected when in range (which is not like a rubber band but this is totally going somewhere relevant.) and the network can stretch to accept multiple devices (see? Exactly like a rubber band.). Each rubber banded device can also communicate with a maximum of seven other devices which can each be rubber banded to seven more, etc., etc. Devices can also be attached to multiple networks at once. This means users can connect Bluetooth devices in endlessly customizable ways to make the most of their electronics.

This hands-free technology makes using a cell phone while on the go much handier (pun intended!). Tasks like driving which would be dangerous to do while using a cell phone in one or both hands, suddenly become safer and simpler.

iPhone Earpiece Repair

iPhone 5 Earpiece Replacement Toronto MississaugaiPhone Earpiece Replacement Toronto & Mississauga.

The earpiece is a little speaker located just above the display of your iPhone. It is attached to the frame that holds the screen from the inside and connects to the logic board through the same cable, which connects the front camera and the proximity sensor. When it fails it becomes very inconvenient to use the phone – you would have to talk to everyone on speakerphone or via a headset. 

There can be many reasons for the earpiece to fail, like physical or liquid damage, electrical failure, etc. The only solution is to get your iPhone earpiece replaced.

Replacing the iPhone earpiece will solve the following problems:

  • Muffled sound coming from the phone
  • Distorted or staticy sound
  • No sound at all

The most common problems we see people have with the headphone jack on their iPhone are:

  • muffled, fuzzy or unclear sound is coming out of plugged-in headphones
  • sound is only coming from one ear of the headphones
  • the headphones are not sitting correctly in the jack – the connection between the headphones and the headphone jack is wiggly or not holding the headphones plug properly
  • your headphones will not plug into the jack at all – usually because something is stuck inside the jack

A few consumer reviews have revealed the iPhone to have a slightly modified headphone jack input which causes some headphones, especially third-party headphones not sold by Apple, to create static, stop headphones from working fully, or even remotely activate Siri.

Many issues with the headphone jack can be fixed with a little DIY, but why risk breaking your phone?

Your phone is often the most important item in your pocket at any given moment. Don’t try to live with the frustration of a non-functional phone. Bring your iPhone to the TechKnow Space and let us do the hard work for you.

iPhone Home Button Repair

This may actually be the most important button on your iPhone and probably the button you use the most! It’s the button you click to go back to your home screen. If your home button becomes damaged or broken, you won’t be able to do many things easily as you were before. You’ll still be able to do things, it will just take much longer to do so. So if your iPhone home button is sticking or simply not working at all, bring it in and we can replace it for you in 1 hour.

On iPhone models that are equipped with Touch ID (fingerprint unlock) the home button itself contains electronics that assist in sensing your fingerprint and unlocking the iPhone.  The home button is matched 1 to 1 with the mainboard of the iPhone.   

After a home button replacement on an iPhone with Touch ID the fingerprint sensor will no longer operate.


iPhone 7 and iPhone 7 Plus doesn’t come with a physical Home button like previous generation iPhones. Instead, it comes with an all-new pressure sensitive Home button, which relies on the Taptic engine to give you a sensation that you have clicked on the button. Pressure sensitive buttons have their advantage. You no longer need to worry about the wear and tear of the home button. Apple used the words “force sensitive solid state” – which means, in a sense, that it’s a lot less prone to breaking or wearing out.

But anything can happen with electronics and if you think your home button has a problem drop in at any of our locations located in Mississauga/Toronto & our technicians will be happy to assist you.

The home button on the iPhone 5/5S and 6/6+ also doubles as a fingerprint scanner, called “Touch ID”, which allows you to unlock your phone with your fingerprint instead of typing in a password, and also allows you to purchase apps, movies, or music without needing to verify your credit card every time.

This is also beneficial for preventing credit card fraud or accidental purchases if you have small children who often use your phone for “pay-to-win” type games or apps, because you can require your phone to ask for a fingerprint scan before completing a purchase.

Touch ID works by layering a few different components on top of each other. The top layer made of a very scratch-resistant sapphire crystal (I guess you could say Apple craves that mineral!).

This layer needs to be scratch-resistant because any imperfections on the scanner can prevent Touch ID from scanning fingerprints properly. Then a stainless steel ring surrounds the crystal which when touched by your finger (your body has low levels of electricity – ‘cuz baby you’re a firework!), “wakes” the actual fingerprint sensor underneath.

This sensor “reads” your fingerprint by taking a very detailed picture of your fingertip and matching it to a scan saved to your phone.

Apple assures their users that the fingerprint data isn’t saved anywhere but on the phone itself, not on their servers or online. This should make the fingerprint data safer from security threats or hacking.

The touch software is programmed to request a pass code or password in certain situations before it will re-enable the scanner, for your security:

  • If Touch ID hasn’t been activated in more than 48 hours,
  • If your phone has been recently rebooted or reset to factory settings,
  • If your phone has failed to read your fingerprint correctly 5 times in a row, or
  • If you’ve remotely locked your phone using an app like Find my iPhone (usually if it has been stolen or lost).

The Touch ID can also help replace your wallet with a new program called Apple Pay, a “contactless payment” system. It is available at some places in the US, but not currently in Canada. Apple has plans to bring Pay to Canada some time in 2015.

This software allows users to quickly tap their phone against the credit card terminal at a variety of places, instead of swiping their credit card or entering their PIN. It also works with a huge range of online stores and apps. Apple Pay also allows you to store more than one card, just like your actual wallet.

“Banks are clamping down on their verification processes for the Apple Pay mobile-payment system after crooks started loading stolen credit-card data onto phones and then making fraudulent purchases...The banks are making customers jump through more hoops because they want to make sure that card really belongs to the person who is loading it into the phone.”

--Wall Street Journal, March 2015.

The iPhone 6 Plus’ large size meant Apple needed to add an additional function to this phone, called “Reachability”. The large screen-size makes touching all parts of the phone when holding it in one hand difficult for some users. By double-tapping the home button, everything on the screen is shifted to the bottom half for greater ease of use. This function works, regardless of whether you are:

  • in a third-party app,
  • on the home screen,
  • surfing the internet, or
  • using any other function on your phone.

Without a working home button, you will not be able to use your phone for a lot of the things you usually use a phone for, such as:

  • returning to the Home Menu from a web browser or app
  • using Touch ID to make purchases
  • unlocking your phone’s screen with a fingerprint scan

Once your iPhone’s home button works, you will be able to:

  • Capture screenshots of what is displayed on your phone (press the home button and the power button at the same time)
  • Make secure credit card purchases and bank payments online with a swipe of your fingerprint
  • Exit out of apps or other open windows quickly
  • Use voice commands and access Siri for searches, contacts and more
  • Bring up all open apps in the “multitasking” window (press the home button twice to use this option)
  • Open up your list of recent calls and favourite contacts (double click the home button to find this list)

With such an important part of your phone out of commission, you will definitely find using your phone much more difficult. Bring it in to the Techknow Space and walk out within an hour with it back in action.

What is iPhone Touch IC Disease

iPhone Touch Disease, or Touch IC disease as it is so-called is a failure of on the mainboard of the iPhone (affecting iPhone 6 Plus models especcially) that casues a degradation and eventual failure of the iPhone's touchscreen response.  

Essentially you will find that over time as you attempt to interact with the iPhone's touchscreen it will become more and more difficult to activate the controls and eventually nothing will hapen when you touch or swipe.

Some are calling this problem (which Apple has acknowledged exists) a defect.  However Apple's website indicates that the failure is a result of repeated drops, knocks and/or other stresses experienced by the iPhone. They are neither covering failure under warranty nor repairing the damage -- leaving affected users to their own devices to find a solution from a third party repair shop.

The cause of the problem consists of the failure of 2 integrated circuits on the iPhone mainboard - namely the U2402 & U2401 chips which require replacement in order to provide a solution.

iPhone touch disease showing grey bar

A distorted grey band may show intermittently at the top of the display.

This distinctive grey band is usually a tell-tale sign that your iPhone is suffering from the mainboard surface-mounted component failure known as Touch Disease, Touch IC Disease or Touch IC Failure.  





Data Recovery from iPhone With Damaged Mainboard

When your iPhone mainboard is damaged, you haven't synced your iPhone's data with iCloud, AND you consider that data to be vital business information or irreplaceable nostalgic photos and videos (for example) -- you may not yet be completely out of luck!

There is more than one approach to go about recovering data from a damaged iPhone. 

1. The iPhone doesn't work but powers on to the point where when interfaced with a computer and software data recovery is possible.

2. Repairing the mainboard damage sufficiently to allow access to the iPhones memory and using a host computer and data recovery software.

2. Removing the on board storage integrated circuits and recovering data from the on-board flash storage using a specialized iPhone flash IC host. 

Bring your damaged iPhone in to us and we will determine the best (if any) method to recover your iPhone data. 

iPhone Wont Turn On Due To Mainboard Damage

An iPhone that doesn't turn on after damage to the mainboard as a result of impact, liquid exposure, heat etc. is not necessarily bricked forever. 

Depending on the circumstances that led to the damage there may be a short circuit, an open circuit that should otherwise be closed, or a capictor or other surface mounted 'power-management' component may be damaged.

Extensive testing using microscopes and infrared heat sensors to specifically identify the damage, and subsequently repairing circuits or replacing components with micro-soldering and reballing tools is required.

The entire process of repairing an iPhone that has mainboard damage preventing it from powering on can take several days.

What Causes The iPhone Blue Screen of Death

The iPhone Blue Screen (Of Death) is a situation where during normal operation of the iPhone or when interacting with certain apps it suddenly goes to a all blue screen and may freeze - requiring a hard reboot. 

Typically, there are 3 common possible causes of the dreaded Blue Screen on an iPhone.

  • Damaged, or mis-seated Home Button Connnector
  • Damaged proximity sensor ribbon flex cable
  • Damage to the mainboard itself - usually as a result of long screw damage.

Having determined (preferrably by a competent repair technician) that the cause is not either of the 1st two mentioned, you will need an iPhone mainboard repair. 

iPhone iTunes Error 4013

The most common question asked by iPhone users finding themself in this situation is "Can I get my iPhone working again AND save the data?"

When the cause of the the 4013 Error (Cannot Restore iPhone) is mainboard failure there is no way to restore functionality while also saving the data on the iPhone.  

The NAND chip (integrated circuit or IC) requires reprogramming which will - while restoring functionality - will also restore your environment to factory defaults, with no data.  

iPhone Microphone Repair

If your microphone isn’t working properly you’ll notice straight away. If your caller cannot hear you on the phone, even though you can hear them, most likely your microphone is failing. If this is happening to you, bring in your iPhone and our technicians will have your problem fixed in 1 hour.

iPhone 5 Microphone Replacement Toronto MississaugaIf your iPhone microphone has failed or is failing, you might experience one of these issues when you make a call, or try to record audio:

  • People can't hear you during a phone or FaceTime call

iPhone Power Button Repair

iPhone 6 and 6 Plus Power Button Replacement Toronto MississaugaYour iPhone power button on your phone can become damaged over time, simply by use, or drops. You’ll be able to notice once it has become damaged, it will look like its sinking into the phone, or it may be slanted, eventually if it is not repaired it will become impossible to turn on or off, so before it gets to that point, or if it is already at that point bring it in and we can replace your iPhone power button in 1 hour.

The power button on your phone is vital to locking the screen to prevent pesky butt-dialing (my butt always calls the pizza place) and also for waking your phone back up from a locked state or powering it down completely (although in this day and age, turning off your phone is probably less common than chewing your own arm off). This button is also sometimes referred to as:

  • The sleep/wake button,
  • The on/off button,
  • The hold button, or
  • The lock button.

The power button does more than just turning the screen on and off, or at least it does in iOS (Android users are not as lucky, unless you are willing to download a totally new OS, or reprogram the button yourself – both options have risks and rewards attached). The lock button, when pressed at the same time as the home button, saves a picture of what is currently displaying on your screen. This is called a “screenshot.”

The lock button on the iPhone 6/6+ has been moved from the top of the phone, unlike in all the previous models, from the side of phone. Reviews from users and consumer blogs have been divided pretty evenly. Some users have adjusted to the change fairly seamlessly while others have noticed issues with the placement of the button directly opposite to the volume adjusters on the other side of the screen.

According to these users, the way both sets of buttons are placed on the phone makes it pretty difficult to avoid pressing both sets of switches when you only want to hit one. Problems associated with the new design as noted by users have been:

  • Pressing the volume button accidentally and opening the camera app and then taking photos without meaning to (the volume buttons trigger the camera shutter when the camera is on)
  • Locking the phone instead of changing the volumes
  • Having to place your hand in a weird way to avoid either of the above issues (which is fine if you are some kind of hand contortionist or double jointed, but not for the rest of us).

If the power button on your iPhone 6 or iPhone 6 Plus is not working, the current workarounds built into the software are pretty unwieldy and annoying to use. To lock or power down your phone without a hold button, you need to:

1. Search through your settings

2. Turn on Accessibility/Assistive Touch

3. Create a shortcut to use the Assistive Touch feature because without it there is a pretty annoying grey box taking up a portion of the screen

4. Triple- clicking the home button will activate the Assistive Touch menu (which is additional wear and tear on the home button, on top of your already malfunctioning lock button)

5. And then select the function you want, lock or screenshot or camera, etc.

You need a fully working phone. There’s no question about that. So why would you live with a broken phone? When you bring your iPhone to the Techknow Space for a power button repair, you will soon be able to do all the things you used to with your phone, like:

  • Using the power button to silence incoming calls, or dismiss the call entirely (click the button once for mute, twice to reject the call)
  • Take screenshots of what is currently displayed on your screen by clicking the home button and the power button at the same time
  • Lock and unlock your phone’s screen with one touch
  • Turn the screen on while on a phone call

Don’t settle for less with your broken iPhone. Don’t struggle daily to use your phone. Phones are supposed to make your life easier, not more frustrating. Bring your iPhone to the Techknow Space and get the lock button replaced within one hour by our certified, expert technicians.

Apple has admitted to problems with the power button on previous models. They have even been sued a time or two in the US over the faulty construction of the cable which connects the button to the rest of the phone’s guts, especially in the iPhone 4 and 4S. But that doesn’t exactly mean they are eager to help users fix the problem. That’s not to say you should try fixing the problem yourself either.

Fixing the power button on your own is a complicated mess and really, who needs more mess in their life? Unless you’re Mr. Clean or maybe an army of Roombas (or is the plural Roombi? Roombus? Roombopodes?), no one wants a messy situation. Just let us do the hard work for you.

To fix the lock button yourself you would need to:

1. Remove all the itty bitty screws from the outside of the phone

2. Carefully take the screen off. This is not as easy as it sounds: you can run the risk of shattering the glass or damaging the connecting cable. This step also either requires a special suction cup tool or very steady hands and a good quality suction cup. (Not one of those ones that slide off the car window 30 seconds after attaching your fuzzy dice to the windshield.)

3. Veeeeeeeeery carefully undo the clips holding the screen to the frame and disconnect the cable between the phone and the screen

4. Remove more screws – don’t mix these ones up with the other ones from the outside (still think this is a good idea? The difficulty level shoots up soon, hope you’re ready for it)

5. Pry up the cable connectors BUT not the actual sockets of the home button, digitizer and display (you might need an old timey Sherlock Holmes-type magnifying glass for this (ok, you don’t actually need an old timey one, but those totally look cool, right?)).

6. Remove EVEN MORE screws (also don’t mix these up. By this point you should be drowning in loose screws – and I don’t just mean the ones from the phone haha)

7. Remove internal cables powering the phone.


9. Remove the antenna cable and logic board – also very important parts


11. Finally!!! You have reached the power button. You did it! Now all you have to do is install a new one and do all of that IN REVERSE.

12. Good luck!!!!!!

iPhone Proximity Sensor Repair

Q: What is an iPhone proximity sensor?

A: The iPhone proximity sensor is the component in the iPhone that turns the screen (display and touchscreen) off while holding the phone to your ear while on a call to prevent the touchscreen from disconnecting the call or activating any other function.

Troubleshooting Common iPhone Screen Problems

Cracked or broken touchscreens, LCDs, and glass are the most common problems with any iPhone. Many people mistakenly believe that Gorilla Glass is unbreakable, which is not true. Corning Gorilla Glass on an iPhone is a great improvement, making it less easy for the digitizer or screen to get scratched, but it is still easy for the screen to crack or break.

Often, the digitizer or the LCD part of the iPhone screen may not be visibly broken, but does fail to work due to repeated knocks, dings and drops. So, while the glass screen has no visible crack, it might be white or unresponsive to the touch. After suffering multiple knocks and drops over time, just the slightest impact may render it inoperable. This is a perplexing but common experience for many users who can’t understand why a very slight impact resulted in the failure of their touchscreen..

A damaged LCD can also be bleeding the liquid that is sealed within it. This impact often results in hair-line cracks that are often invisible to the naked eye. Over time, however, repeated knocks can widen and deepen the cracks until they are large enough to seep out liquid.

Using your iPhone with a partially non-responsive or a fully dead screen is very frustrating. It means you can’t access a portion of your apps or are not able to see any display at all!


Outer Screen (associated with the iPhone digitizer, glass, or the touchscreen) problem symptoms include:

  • not responding to your touch
  • glass is cracked or broken
  • glass moves downwards when touched
  • You can’t “slide to unlock” 
  • The screen is badly scratched and difficult to see through

Your iPhone’s LCD will likely need to be replaced if you experience of the following:

  • Cannot see any image on the screen
  • The screen is displaying lines
  • The display is intermittent
  • The display has bleeding (the liquid in the Liquid Crystal Display is bleeding through the hairline cracks in the LCD glass.
  • The screen is dark/black 

For any of the above, your screen assembly needs to be replaced. Bring your iPhone to The TechKnow Space and let our expert technicians replace the screen within an hour.

Further Damage not Addressed by a Screen Replacement

Typically, your display or LCD gets damaged because of a hit, bang or a drop. When this happens, you are unable to use your iPhone since you cannot see what is displayed on the screen. It is possible that the bang or the ding has also damaged other components on your iPhone, like your headphone jack, loudspeaker, earpiece, wifi antenna, etc. We can often only discover these failures once we have replaced the screen, and can observe the behaviour of your iPhone functions on the display. Should we identify any additional repairs needing to be done to your iPhone, we will call you for confirmation before completing any repairs. 

In situations where your iPhone screen is not the only problem we may need to perform additional diagnostic work to determine the cause of the problem and the repair approach which can take more than an hour and sometimes up to a day.  (We will always keep you posted during the repair process!)

Frame Damage

Sometimes when the drop that damages your iPhone screen also causes damage to the frame as well. The iPhone’s case may become dented, bent and otherwise deformed, preventing the new replacement screen from being installed properly.

It is crucial to address the issue with the frame before installing the new screen, as doing the installation on an imperfect frame could cause stress on the glass, and make the screen crack with a minimal amount of force applied to it.

In the event if we find damage that requires some minor adjustment, we will perform the repair at no extra charge to you. If the frame is severely deformed (and sometimes that can only become evident after the cracked screen is removed) we will call you and inform you of an additional charge (typically less than $20) for realigning the frame and with the costs of replacing the housing entirely.

Again, when we discover any issues with your device beyond just a screen replacement, we will inform you and ask for your confirmation before we do any iPhone screen repairs.

A Review by Mike Wakunick

"This place offers exceptional service for an affordable price. I've been here twice over the last 3 years (iPhone 4 screen repair). They quoted me the standard 1 hour service for the repair to be completed, and it was finished within 20 minutes. As we all know, it's imperative to have our mobile devices working top notch, and we cannot be without them for a week while they are sent in to some unknown location to be repaired. TechKnow space is trustworthy, and you will get your device back the same morning or afternoon - 1 hr for phones and 2 hrs for tablets. They even have a customer lounge area with free wi-fi and a large screen TV for you to use while you wait for your repair to be done. Otherwise, you can leave and come back. Always have had great experiences with TechKnow Space, and will continue to be a customer here in the future! :)"

Breakdown Of The iPhone Screen By Layer and Repair Statistics

An iPhone screen needs to be replaced when either one of the two components has sustained damage:

  1. The outer screen: This is also referred to as the Touchscreen or Digitizer or the Glass.
  2. The inner screen: This is also referred to as the Display or the LCD.

The original first 2 iPhones came with two screen components installed separately.

All other iPhones come with the two screen components fused together as one complete assembly making them impossible to repair individually. Apple has decided to do this for several reasons:

  • With a fused touchscreen and LCD there is never an issue with dust getting in between the layers of the screen

  • The screen is thinner, as there is no air gap between the digitizer and the LCD. This allowed Apple to make iPhones a little thinner overall

  • The thin iPhone screen makes the colors of the LCD look more vibrant and the image clearer.

In our experience we have learned that the primary reason for iPhone Screen Repairs is broken glass, followed by LCD only broken, and in the fewest cases we have seen screen failure without any visible damage or breakage - see the breakdown by failure in the following chart:

iPhone Screen Repairs - Breakdown by Screen Layer

iPhone Screen Repairs vs All Other Component Repairs

Repairing The iPhone Glass & Touchscreen

For the top layer of any iPhone screen there’s a layer of Corning’s Gorilla Glass. It’s a specially treated toughened glass designed to withstand drops and dings in order to prevent the glass from getting cracked or scratched.

During its manufacture, the glass is toughened by ion exchange. The material is immersed in a molten alkaline potassium salt at a temperature of approximately 400 °C, wherein smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath. The larger ions occupy more volume and thereby create a surface layer of high residual compressive stress at the surface, giving the glass surface increased strength, ability to contain flaws, and overall crack-resistance, making it resistant to damage from everyday use.

Just keep in mind that as resistant as it can be, it is still glass.

The glass is a part of your iPhone’s screen not because smartphone manufacturers want to make phones particularly frail or weak, but because it is an important part of how the screen reacts to touch.

Touchscreens on all cell phones use a technology called “capacitive sensing”. This uses a layer of glass as an insulator (which means it does not transmit electricity), coated with a conductor (which can transmit electricity).

The conductive layer is usually a combination of metals called “indium tin oxide” (ITO). These metals are transparent, so you can see what is being shown on the display underneath.

Because the human body is also an electrical conductor, when your fingers make contact with the touchscreen, the conductive coating registers this as a change in the iPhone screen’s electric field. This is how your iPhone knows where you are tapping or dragging on the screen itself, even if you use multiple fingers at the same time.

Touchscreens use a series of steps to process the information entered by touching your iPhone’s screen:

  • Your iPhone registers touch by analyzing the area of the iPhone screen interrupted by electrical impulses (finger, stylus, etc.) for size and location.
  • iPhone software inputs the data taken from the touchscreen and calculates the features of the gesture.
  • The software combines the touch with the application in use and carries out the action and sends out additional information if necessary to other parts of your iPhone’s screen or extra hardware.
  • If the software completes the process and can’t match a gesture with an action, your iPhone will ignore the touch as an accidental input.

All of this happens almost instantly. In fact, you probably will never notice a delay between touching the screen and the action happening. Not only can your iPhone do all of that in a nanosecond, but it can also calculate multiple touches at once, like two finger gestures such as zooming in.

You might think that touchscreens having a “multi-touch” capability is new technology. And it is pretty new, relatively speaking. In 1982, a group from the University of Toronto created a screen made of a camera behind a pane of glass which could register any human input. This awkward and hard to use interface was improved by U of T in 1985 with the first version of the modern touchscreens we know and love today.

Apple claimed they invented the multi-touch technology in 2007 with the release of the first iPhone, but both the phrase “multi-touch” and the actual function itself existed well before the rise of the iPhone. However, they are not being completely dishonest, as Apple holds several patents for the mobile device version of the technology.

Apple prides itself on user friendliness, and the iPhone screen interfaces with users in a very natural and intuitive way. The iPhone touchscreen can register your finger or stylus regardless of pressure or surface area. That is to say, the iPhone’s screen is sensitive enough that pressing hard or with a wider stylus isn’t necessary for accuracy or effectiveness.

The gestures accepted by the iPhone touchscreen are also very natural-feeling. Using multi-touch gestures to do a variety of movements, such as scrolling the screen, or expanding or shrinking the screen’s contents are often naturally understood by the user.

Repairing The iPhone LCD & Back-light

Most smartphones use LCD technology for screens because it is thin and relatively cheap when compared to its lifespan.

The display of your iPhone is a high definition “liquid crystal display” or LCD for short. Liquid crystals might sound like something impossible, because how can something be both a liquid and a solid at the same time? But because these crystals can do both at the same time, the result is a screen which can display millions of different colours with no visible delay.

These liquid crystals are laid out in between two pieces of polarized glass, underneath the touchscreen. This layer is then powered by thin wires laid out in a grid underneath the crystals.

The crystals act like shutters, opening and closing above a colour filter composed of tiny red, green, and blue “sub-pixels.” These sub-pixels are invisible to the naked eye, and can be brightened or darkened in over 16 million combinations to create crisp, vibrant images and text.

The crystal component of the LCD is only half of the equation. The liquid crystal layer doesn’t project any light on its own, so your iPhone needs a layer of lighting (usually small, low-powered LEDS). This layer of lights is underneath the rest of the components and is referred to as backlight.

 Starting with the iPhone 4, Apple calls the new screen technology a “Retina HD” display:

“Rather than using traditional methods to create the higher-resolution Retina HD display, we developed an advanced process of photo alignment. This involves using UV light to precisely position the display’s liquid crystals so they lie exactly where they should. Better-aligned crystals deliver a superior viewing experience.”

Their new technology promises a few interesting perks, like increased visibility in direct sunlight or with sunglasses on. Another added functionality of the Retina HD display in the latest iPhones is a wider viewing angle. The “viewing angle” is the largest angle that the display can still be acceptably used at.

Apple says the screens can now be comfortably viewed from almost any angle. This is possible because of the screen’s higher contrast and extra pixels.

iPhone Touch ID Fingerprint Sensor Failure After Screen Replacement


Touch ID Fingerprint Sensor not working after screen replacement on an iPhone 6.


When does this happen?

It is a very rare occurrence -- about 1 out of 1000 screen replacements on average.


Are any iPhone models more susceptible to this failure?

The iPhone 6 Plus (as acknowledged by Apple), the iPhone 6 and 6S are more likely to exhibit this Touch ID issue than are other models.


Why does it happen?

There are a number of possible reasons why this particular issue may arise:

1.  Damaged Home Button Cable:

An easily diagnosed problem - damage to this cable can be seen with the naked eye. 
This damage is not repairable and can only be addressed by Apple (phone replacement for a fee).

2.  Damaged Home Button Extension Cable:

This cable runs from the bottom of the iPhone to the top between a heat-shield and the iPhone LCD.
The extension cable is not usually replaced with a screen (on iPhone 6) as damage to this cable infrequent.
The screen assembly frame must be disassembled to remove this cable and replacement usually solves the problem.
This problem is repairable.

3. Damaged Main-board Circuits:

After impact the behavior and reliability of electronics will ALWAYS be questionable.  
Apple has acknowledged main-board failure on some models under less severe circumstances than screen breakage.

Touch ID failure can happen after a screen replacement (even if it was working after the breakage) for the following reasons:

During screen replacement - the home button must be disconnected from the main-board.

After reconnecting - underlying main-board failure begins to exhibit the symptom of Touch ID not working.

Even after reconnecting the original screen the Touch ID failure can persist.
Disconnecting the battery and disconnecting the components necessary for the screen replacement can result in capacitors on the main-board which were previously constantly conducting electricity and maintaining a charge to drain their electricity and exhibit failure when the power is re-connected.

The only option is replace the phone.

4. Damaged Connectors:

This is most common after liquid damage exposure.
Liquid corrodes the conductive pins on the connector.
This is sometimes repairable.

iPhone Sim Tray Repair

If your sim card isn’t properly your iPhone will certainly let you know with alerts & notifications. Sim tray problems can happen over time, or through liquid damage.If your sim card is properly installed and placed properly in the sim tray and you’re still receiving notifications bring your phone in and we can repair or replace it for you.

When your iPhone is showing a “No SIM” message all of a sudden, even though you made sure that the SIM card is actually in the phone – there could be a problem with your SIM reader and/or tray. You can try removing or transferring your SIM card, insert the tray completely and in the same orientation that you removed it (it will fit only one way).

The SIM card is a small plastic and metal card your cell service provider gives you to put inside your phone so you can use the phone on your provider’s network. A functioning SIM card in your phone allows you to:

  • Make and receive phone calls,
  • Send and receive texts, and
  • Access your cell phone provider’s LTE or 3G network and use the Internet.

The SIM card tray is one of the parts inside your phone you definitely want to make sure is undamaged and functioning properly so that your phone is connecting to your cell service provider’s network, letting you use your phone for its intended purposes. Apple changed the size of the SIM card tray in the iPhone 5 and 5S to fit a “nano” SIM, which is thinner and smaller than the previous model, the “micro” SIM. This new SIM size carried over to the iPhone 6 and 6 Plus as well as all of the iPad Air and iPad Mini models. This change allowed Apple to make their devices, especially the iPhones, slimmer and lighter.

If your iPhone is showing an error message such as:

  • “No SIM detected”,
  • “Emergency calls only”, or
  • “No network found”,

You should remove and then reinsert the SIM card, found on the right side of the screen of the iPhone. If the error message is still there, try putting a different SIM in your phone (borrow one from a friend or family member) and if the message goes away, it is a problem with your SIM and you need to take it to your cell service provider and replace it. However, if it doesn’t, there could be something wrong with your SIM card tray. Issues with the tray can happen for reasons such as:

  • Ejecting or reinserting the tray incorrectly,
  • Liquid damage
  • Physical damage like dropping your phone or hitting it against something
  • Bent or broken connector pins
  • Electrical shorts caused by the metal of the SIM touching another part inside the phone
  • The tray won’t eject or stay inside the phone

The TechKnow Space can troubleshoot SIM tray issues quickly and we are prepared to fix or replace the parts that are malfunctioning, any day of the week.

Without a working SIM card reader in your phone, your phone is essentially a really nice looking brick. You will be unable to:

  • Update Facebook and Twitter without Wi-Fi (gasp!)
  • SnapChat or Instagram your exciting adventures (shock!)
  • Watch your friends’ Vines or check their Tumblr posts (fright!)
  • Or use your cell phone as, you know, an actual phone (horror!!!)

Don’t deprive yourself of the constant connection to social media, calls and texts your iPhone offers. You paid good money for that phone; you should make the most of it, instead of trying to create inefficient workarounds.

2. Losing one or more parts from the inside of the phone while you take it apart

3. Damaging other parts of the phone while removing or reinstalling them

4. Getting everything out of your phone and not being able to put it back in again

5. Managing to get everything back into your phone, but the problem still exists

Don’t risk the chance you might do everything right on the chance you won’t do anything wrong. Bring your iPhone to the Techknow Space for a risk-free repair experience.

Apple is pretty proud of their new design for the buttons on the iPhone 6 and 6 Plus, saying:

“We also thought about how you use your iPhone every day and redesigned the buttons to make it even easier to use. Elongated volume buttons are integrated into the thinner profile, outlined to make them effortless to find by touch.”

Some users have commented that the new design may contribute to what the Internet is referring to as “Bendgate”.

A few reports of frame bending in the middle near the volume buttons appeared online shortly after the phone hit the market. The problem may occur because the area of the frame around the switches has not been reinforced enough, so it can’t survive very long in your pocket without a case.

iPhone WiFi Repair

iPhone 6 WiFi Replacement Toronto Mississauga

iPhones can provide users with a full multimedia experience by allowing users to do things like:

  • stream movies,
  • download music, books and apps,
  • keep tabs on their personal health or home security,
  • use social media, or
  • surf the Internet.

To do any of these tasks, your iPhone needs to connect to the Internet, either by using a nearby Wi-Fi hotspot or connecting to the LTE or 3G network offered by your cell service provider. Using the Internet on your iPhone with a LTE or a 3G network for everything can mean a costly phone bill at the end of the month from your cell service provider.  In order to lessen the impact on your wallet every month, connecting to Wi-Fi with your iPhone is a big part of most users’ phone usage. When you can’t use the Wi-Fi on your cell phone, doing all the multimedia things you are used to doing on your phone becomes expensive and slow. 

Sometimes the Wi-Fi connection problems on your iPhone can be fixed with a factory reset of the phone, but that means if you don’t have the data such as photos and apps that are on your iPhone 6 or 6+ saved somewhere else as a backup, you will have a blank iPhone without any of those files after the reset, and it still might not solve the Wi-Fi connectivity problem. Instead of fussing with all of that, you should bring your iPhone to the TechKnow Space and let our expert in-house technicians fix your Wi-Fi connection problems.

Repairing the Wi-Fi connection will fix issues such as:

  • a “greyed out” Wi-Fi signal or connection,
  • a very weak Wi-Fi signal, or
  • not being able to connect to nearby Wi-Fi networks that appear in the network list on your phone.

Why live with the frustration of using a phone with no Wi-Fi connectivity? Bring your phone to the TechKnow Space any day of the week and get your phone back in tip-top shape! If you are facing issues being reported include not being able to connect to a Wi-Fi network, getting incorrect password prompt, Wi-Fi settings grayed out, dropping connection intermittently or speeds being extremely slow you can drop in at you can walk into one of our locations in Mississauga/Toronto & our technicians will be happy to assist you.

iPhone Wont Power On Diagnostics

iPhone 5 won't turn on Mississauga Toronto.If you are worried your new iPhone is destined to become a very expensive and fancy paperweight because it won’t turn on, don’t worry. There are a few things you can do to try to fix the problem, but if those don’t work, the in-house expert technicians at the Techknow Space can definitely help!

If your iPhone won’t turn on, try to restart it by holding down the power button on the side of your iPhone (referred to sometimes as the hold or lock button, and by Apple as the “sleep/wake” button.) until the screen lights up. If this doesn’t occur, try plugging your iPhone in and waiting about 15 to 20 minutes before trying again.

But if this doesn’t solve the problem, you can try doing a hard reset by holding down the power button and the home button (on the front of the screen) together. You will probably need to hold these down at the same time for at least 10 seconds. If the Apple logo appears on the screen, the reset worked. If nothing happens, plug your iPhone in and try again after charging it for a little while.

If your iPhone still has no smile, try plugging your iPhone in with a different charger, or if the charger and the cable are two separate pieces, try with a different cable as well. Sometimes the charger breaks without you realizing it and can fail to charge your iPhone.

Another possibility is performing a full system restore on your iPhone. This is a pretty drastic measure because a system restore will delete all your information such as photos, videos, and other similar data. If you are reluctant to take this step right away – don’t worry, we at The TechKnow Space can take a look at your phone and see if we can save your information while fixing your phone.

If there isn’t anything particularly valuable on your iPhone, you can perform a system restore:

  1. Plug the iPhone's USB cable into the dock connector, but not into your computer
  2. Hold down the iPhone's Home button
  3. Now plug the other end of the USB cable into your computer
  4. This will open iTunes, put the iPhone into recovery mode, and let you completely restore the iPhone.

If your iPhone won’t turn on because of an impact or a fall or liquid damage, then you will need to bring it  into the Techknow Space to let us open it up and repair or replace anything that might be keeping the phone from turning on.  Some of the other components that could be damaged because of the impact include:

  1. Charging Port – which blocks the charge from your charger to the phone. When this id damaged, it needs to be replaced.
  2. Main Logic Board or the Motherboard – this is the brain of all digital devices, and is typically too expensive to repair or replace

Liquid damage can usually be repaired, but it can have underlying issues that might prevent your iPhone from functioning normally. We have been saving liquid-damaged phones for 9+ years and our experience and advice is documented on our Liquid-Damage Information page: /information/liquid-damage/

If your iPhone still plays dead, bring it to one of our convenient TechKnow Space locations and let our experienced technicians do their magic for you, typically within a few hours.
