1 Hour iPhone Repair




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 company on the stock market.

What kinds of problems can iPhone have?

What Can Go Wrong With an iPhone

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As each iPhone is superseded by a newer version, challenges both arise and dissipate in the realm of iPhone repair.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

iPhone Charging Port Replacement Toronto Mississauga

Logic Board Repair For All Deviceslogic-board


All models made before the iPhone 7 came with a standard headphone jack / audio port that wears and weakens over time and with use.

The headphone jack on any phone is a very small but important part of the phone’s function. The headphone jack is where you plug in a microphone headset or ear/headphones. The headphone jack is located on the bottom of the phone, next to the charging port.

 If your iPhone headphone jack it is acting up, stop by and we can fix it today.

Headphone jacks usually fail or break as a result of physical damage, overuse or simply wear out.  If your headphone jack issue seems sudden or not as a result of any force you could be looking at a mainboard issue.  A failure of the audio controllers can result in the need for a repair to the iPhone mainboard.


iPhone Camera Replacement

When other repair shops can't solve your iPhone camera problem we can guarantee an iPhone camera logic board repair 9 times out of 10. 

Logic Board Repair For All Deviceslogic-board


Most of us rely on our phone secondarily for its use as a camera or for taking videos - so when your iPhone camera fails or the image doesn't look quite right it is a significant problem. Any of these symptoms may indicate a camera failure.

Dark spots, or broken glass on the camera itself is an obvious sign that the camera needs to be replaced, but if after replacement there's more trouble - like the camera app won't open or crashes, or the camera app shows only a black screen - the mainboard may also have taken on some damage. In this less frquent situation the mainboard may need to be repaired.


iPhone Power Button Replacement

When other repair shops can't solve your iPhone power button problem we can guarantee an iPhone power button logic board repair 9 times out of 10. 

Logic Board Repair For All Deviceslogic-board


A seemingly simple part of your iPhone - the power button - you probably rarely think of relying on it until it has a problem, but when it doesn't work it's the most important!

Although much less frequent than having a broken power switch - damage or failure in the logic board itelf may be causing a power button not to operate in which case you may need a power circuit repair to the iPhone's mainboard.



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.


iPhone Loudspeaker Replacement

When other repair shops can't solve your iPhone loudspeaker problem we can guarantee an iPhone loud speaker logic board repair 9 times out of 10. 

Logic Board Repair For All Deviceslogic-board


Problems with your loud speaker? We can fix all the following loudspeaker failure within an hour. What good is your iPhone if you can't hear it or it can't hear you? 

Loudspeaker problems may not always be related to a failure of the speaker itself -- especially if you are experiencing additional audio-related issues. If changing the loudspeaker doesn't bring back your high-fidelity loud music or crystal clear speakerphone conversations we'll have to look at a mainboard repair.

The loudspeaker on an iPhone if damaged by liquid or through extensive use, once it’s damaged you may not be able to hear your phone ring, music, or the caller on speakerphone setting.


We can replace your iPhone loudspeaker in an hour, so stop by so you don’t have to worry about missing your calls.


iPhone Earpiece Replacement

Earpiece has been replaced on an iPhone 

When other repair shops can't solve your iPhone earpiece problem we can guarantee an iPhone earpiece logic board repair 9 times out of 10. 

Logic Board Repair For All Deviceslogic-board


The earpiece speaker 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. 

As with loudspeaker problems replacing the earpiece will usually bring back sound for regular phone conversations. But sometimes the failure is deeper and replacing the earpiece again and again will only result in the same cold silence. A mainboard repair may be the solution.


iPhone Microphone Replacement

Logic Board Repair For All Deviceslogic-board


Did you know that most iPhones have 3 separate microphones? One is typically used when shooting videos, the other when you talk on speakerphone, and the third one for regular phone call conversations. 

Microphone failures can be a result of dirt or liquid exposure, simply an electronic failure, or in rarer cases may be a result of another problem that has affected the main logic board.  if this is the situation our technicians will diagnose the problem and reccommend a logic board repair for the inoperable microphone function.


iPhone Housing Repair

Over time your iPhone housing will incur scuffs, dings - even dents - becoming unsightly. Instead of hiding it in a thick opaque case - a housing replacement will have your iPhone looking like new.

Home button damage i almost always obvious: to you - in the case a physical damage to the button itself, and to a technician in the case of internal damage to the cables and connections (especially in the case of screen breakage).  When the problem is not so obvious and the standard repairs don't restore thumb-command we'll likely need to repair the mainboard to make your home button work again.

iPhone Proximity Sensor Repair

When other repair shops can't solve your iPhone proximity sensor problem we can guarantee an iPhone proximity sensor logic board repair 9 times out of 10. 

Logic Board Repair For All Deviceslogic-board


The proximity sensor sends a signal to your display to turn it off when you hold the phone to your cheek while making a phone call. This component can be damaged along with glass breakage.

Rarely does a proximity sensor fail independantly.  When it does it usually because it has been smashed and needs to be replaced.  In very rare cases the logic-board mounted connectors become damaged or the on-board controllers have become overheated or shorted requiring a mainboard repair.

Not being able to adjust your iPhone’s sound level may seem like not a big deal at first, but you will soon run into situations when you really wished you could. Just drop by one of our stores and we crank up the volume on your malfunctioning volume button.

Volume woes can usually be resolved by replacing the buttons, straightening bent frames, or replacing cables. Sometimes even after all this the problem may persist - which indicates the mainboard has suffered trauma and need to be repaired to give you back control of your sound levels. 

The volume buttons are found on the left side of your iPhone - they control the sound output and ringer volumes for your phone.


If one of these keys becomes damaged, you may not be able to adjust the volume during calls.If you’re experiencing difficulty with your volume buttons, bring your iPhone in and we can repair it for you.

If your mute switch doesn’t work you could still turn the sound off through the settings in your iPhone, but you would get frustrated pretty quick. We can fix any issues with your mute switch within an hour.

Mute buttons rarely fail wihtout some kind of physical impact damaging the button, the frame around it, or the tiny switch and cables inside the phone.  Replacing the switch, button or cables usually will fix the problem but when it doesn't it means the damage is more extensive and likely in the mainboard itself.

iPhone SIM Tray - SIM Slot - SIM Reader Repair

Earpiece has been replaced on an iPhone 

When referring to an iPhone SIM tray in the context of repair - the iPhone SIM reader is likely where the problem is.


The SIM reader is the electronic component on the main logic board which allows the iPhone to communicate with the SIM card.


A SIM card (A) supplied by your carrier gives your iPhone access to their cellular network (for phone calls) and LTE network (for data). 

The SIM card is placed into the SIM tray (B) which acts a caddy that fits into the SIM Slot (C) on your iPhone.

Once inserted into the slot the contacts on the SIM card make a connection to the pins of the SIM Reader (D).

How a SIM card goes into an iPhoneHow a SIM card goes into an iPhone


When you see messages on your iPhone like:

  • 'SIM Not Detected'
  • 'Not Registered on Network'
  • 'Invalid SIM'
  • 'No SIM Card Installed'

it typically means we will need to do a repair on the SIM Card Reader located on the main logic board.
