About iPhone Repair

holding a repaired iPhone at TechKnow Space

At The TechKnow Space, we repair most iPhone problems in less than 1 hour.

The world was changed when the first iPhone was released on June 29th, 2007. Much more than just a mobile phone, it was the face of a new generation of personal computers and mobile assistants.

Since then, there have been newer iterations about every year, which were of themselves "revolutionary game-changers" for the mobile phone industry.

The ongoing success of the iPhone has helped Apple to become one of the highest valued traded company on the stock market.

New features, faster processing and improved visual graphics were introduced with each release of new iPhone models. 

Every model and component has a distinctive method and procedure for repair.


  • The iPhone 6 screen is mechanically sealed and has a long home button flex cable that needs to be transplanted when changing the screen.

  • The iPhone 7 screen is sealed with adhesive and has its home button flex cable integrated into the screen assembly.


As each iPhone is superseded by a newer version, challenges both arise and dissipate in the realm of iPhone repair.

Users of the new 2017/2018 iPhone models almost immediately began to realize just how fragile these new iPhones are.

One drop on the concrete and the glass touchscreen smashes, or - oops I left it on top of the car and it fell off now it won't even turn on!

From simple scratches to seemingly complete failure - we repair all iPhone models and all damages.

What can go wrong with an iPhone

Common problems an iPhone can have

The battery can die. 

An iPhone battery is good for about 500 to 1000 cycles. When it gets over 500 cycles your iPhone battery will not hold its full capacity.

The camera suddenly stops working

A drop or a knock - even if it's not serious enough to break the glass - can cause internal damage to the camera.

Touch ID stops working

The iPhone won't read your fingerprint to unlock

Touchscreen doesn't swipe or tap

A good knock can kill the digitizer evn of it doesn't beak the glass.  Screen replacement is usually the necessary evil/good ;)

Unable to update to the latest iOS

Software problems and damage or both could contribute to an iPhone being unabel to update its firmware and iOS versions.

WiFi drops connection or limited WiFI range

Physical damage is usually the culrpit whenyou experience WiFi woes.

iPhone got really slow and the battery doesn't last.

Some models of iPhone will slow down when the battery isn't so good to keep it running longer without shutting down.


Troubleshooting iPhone Problems

When an electronic device is damaged such as when dropped, there's usually a primary or visible physical effect, like a dent or broken glass. Typically we can identify (or you can even guess) the component that is damaged and replace it to fix the problem.

Fixing the obvious primary problem may not necessarily be  the only issue. Other components within the device could also have been damaged. This can only be discovered and identified upon complting a diagnostics by running an exhaustive set of tests that exercise all the functions and features of the device to uncover any secondary / additional issues and problems. This enables us to provide you with a complete assessment of your device condition and estimated time and cost to repair. The outcome of our efforts is thus a complete solution, not merely a repair of the visible problem.

Importantly, these secondary problems sometimes cannot be identified or uncovered unless the primary problems have been addressed.

For example:

An iPhone with a damaged touch screen can be fixed by replacing the screen. The device may however, have also suffered damage to the earpiece. This would only be discovered after the screen is replaced and additional testing is possible. Thus, in this example, the solution requires two components to be replaced.


Display & Touch

Screen damage is probably the most common reason phones and tablets are brought in for repair. 

Sometimes the event that precipitated the glass to break (or maybe the glass didn't break but the screen is black) caused unseen damage beyond the screen assembly itself affecting other functions or preventing a new screen from working.  In such cases the unseen damage will need to be repaired before a new screen replacement will revive your device.

Not Charging Properly

You plug in your device to charge - no beep, no charging indicator - you think: "oh no I need the charging port replaced".  

Often it is that simple, however the charging port is related to other functions and components like the battery and mainboard charging circuits.

We look at all possible scenarios when diagnosing a faulty port and provide the solution(s) that solve your charging problems!

Battery Problems

Battery problems come in different flavours.

Often it is easy to know when your battery needs replacing - most devices will give you a message leading up to it.  

When replacing the battery isn't a solution or only partially improves the functionality - we will need to to look deeper.

Sound Problems

Sound Problems - Earpiece Symptoms

Earpiece issues interfere with your ability to hear the other party when on a call - unless you switch to speakerphone.

Often a straightforward replacement of the earpiece speaker will solve this problem. 

Sometimes (and depending on the nature of the damage be in water or impact or ...) the problem could run deeper.

We have even seen (though rarely) software to be the culprit of earpiece problems - especially in the absence of an apparent damage.

Phone Repair FAQ

Screen Issues

There are very few phones being manufactured today with the glass touchscreen as a separate component. Therefore most phones require the replacement of the entire screen assembly as one part. See a list of all phone models with screen, glass & LCD replacement pricing.

When your phone seems to be working (i.e. it's ringing etc.) but the display stays off the most probable cause is LCD failure requiring screen or LCD replacement.  In some very rare cases the display controller circuits on the logic board could be damaged instead or even as well.

There are a few known cases of touch response issues due to motherboard failure however the vast majority of touchscreen problems require the screen to be replaced.

Your phone has a component behind the screen called a proximity sensor. This sensor detects when you hold the phone to your ear and turns off the display and touchscreen preventing functions from being activated by your cheek.

This sensor rarely fails on its own -- it can easily be damaged if the glass covering it is shattered.

If your device has sustained damage during drops and impact, sometimes the frame or housing of the device becomes warped or bent.

This can create a problem when installing a new screen - as the mounting points may not align, or the frame is bent inward impeding where the new screen needs to be.

Fortunately in most cases we are able to straighten and/or repair the frame and proceed to install your new screen.

Power & Charging

Panic! Your phone won't turn on. What now?

It's diagnostics time.  We will perform a thorough inspection and determine where the fault lies.  

No power problems could include the following possible causes:

Behaviours that may be related to a battery problem could include:

  • Phone turns off suddenly
  • Running slow
  • Laggy touch response
  • Won't fully charge
  • Battery swelling
  • Screen has broken (seemingly on its own) from internal pressure

If your charger won't plug in it's pretty obvious that there is physical damage and the port needs to be replaced. wink

... But damage to the charging is port is not always readily visible. 

Symptoms of charging port damage or failure may include:

  • Loose connecter - charger doesn't firmly plug in
  • Charging stops or is intermittent
  • Does not detect when a charger is plugged in
  • Does not detect on a computer

Camera Problems

Whats going on when lining up for a nice shot and the image is always blurry or the view is constantly shaking?

These are some possible causes

  • Scratches on the external camera lens
  • Scratches on the inside camera lens
  • Damaged or broken focus

Blurry or out of focus images can be a result of a dirty or scratched lens, either the external protective lens or the internal camera lens itself. If cleaning the lens doesn't resolve the issue then either the camera or the lens needs to be changed

If the image is shaky or appears to be vibrating then the focus mechanism within the camera is damaged and can be fixed by replacing the camera.

In some cases you might see dark spots in the image while trying to take a picture and also appear in the final image. These are likely caused by a scratch to the internal lens and can be fixed by replacing the camera component. 

Typically, this occurs when the external lens has become damaged, exposing the internal camera mechanism which has become scratched. Other times, this can happen from liquid or dust particles getting inside the camera.

Let us change your camera or lens so you can go back to taking awesome photos.

Audio Problems

Having already tried another pair of earphones wink you've still got no sound.

Here's what could be wrong:

  • Damaged connectors inside the audio jack
  • Damaged audio jack mainboard connector (especially if the phone has been opened)
  • Water or other liquid inside the jack

Most phone audio jacks (headphone jacks) are replaceable as a component and we stock jacks for most common phone models.


"Are you there?"

You answer your phone but it seems no one can hear what your saying.  

The microphone has failed. Most phone mics can be replaced within 1 hour.

When you answer the phone and it seems like there's no one there - you can't hear anything - you quickly switch to speakerphone and all's well you probably have an earpiece (receiver speaker) failure.

Most phone earpiece speakers can be replaced within 1 hour.

The speakerphone function usually relies on the loud-speaker to produce sound -- the same speaker that plays music, notification sounds and ringtones.

If the functions above aren't working you will need your loudspeaker replaced.

Signals and Antennas

Only after a thorough diagnostics will our technicians be able to determine if the antenna is a cause of your WiFi woes.

WiFi problems could be caused by software issues, a failed WiFi transceiver, the antenna, or even logic board damage.

Bluetooth connection issues could be a result of:

  • Impact - affecting the logic board
  • Heat problems
  • Antenna connections
  • Software

We will diagnose your bluetooth connectivity problems and advise accordingly. 

There are many possible casues of a loss of carrier signal - meaning no voice calls & no data connection.

Possible causes include:

Our technicians will perform diagnostics and determine the cause of the connection loss and advise the you of the necessary solution.

What does it mean when a phone is blacklisted?

A phone's IMEI may be blocked by the original issuing carrier for any number of reasons - for example having been reported stolen.

This means that your device will not be able to work with any North American carrier network.  

How to check if a phone is blacklisted.

Buttons & Housing

Sometimes the physical button itself has worn or broken and requires replacement. We stock buttons for most common models of phones. 

In other cases the switch underneath the button is the problem - which we also repair.

Housing replacement on many phones is intricate -- requiring complete dissassembly.

Back covers can be replaced on most phones within 30 minutes.

We stock housings, and back covers for most popular phones.

There's no plastic or amunimum goop that can fix a bent, cracked or warped phone housing. There's only one way to go:

Logic Board Repairs

Logic board replacement for phones can often be as expensive (or more) than replacing the entire device. 

We do however do logic board repairs.

A Motherboard or main-board or logic board is the Central Nervous System or the Brain of a devices.

All components on a device, be it the screen, charging port, microphone or any other component on the device has a corresponding software or functional counterpart on the logic board that communicates with the component.

When the function, say for the microphone, gets damaged on the logic board there is no way for a microphone to work unless the logic board is replaced, or the functional software capability for the microphone on the logic board is repaired.

Replacing a logic board is rarely cost-effective. New logic boards can only be sourced from the manufacturers who will not typically supply these to repair shops. Also, since your data and apps reside on the flash memory on the logic boards, all your data is lost when you replace the logic board.

Logic boards can however be more cost-effectively repaired. There is a 50% success  rate with repairing logic boards. This has the advantage of having all your data and apps available for you to use. smile

Damaged SIM trays can often be repaired. On some phones it is a separate component and can more cost-effectively be replaced on its own.  

More often than electronic failure - the connector pins which contact the SIM card get bent or broken off from inserting an object into the slot, or even inserting the SIM backward.

We repair and replace damaged SIM reader trays typically within 1 to 2 hours.

Saving Data

Depending on the nature and extent of the damage your data may be able to be saved.

For example your phone's LCD has failed but it's an old model and a screen replacement is more expensive than buying another phone. In ths case we can extract your phone's data to external storage media such as a flash drive or onto another phone.
