If your iPhone is not turning at all there could be number of problems associated with this behaviour (or lack thereof ;) - When your iPhone has no power it may be caused by one or more of the following issues:


When replacing parts does not provide a solution or resuscitate your device, the only explanation is a failure of the Main Board or the Logic Board.
When a device suffers damage, the obvious problem(s) appear to be a component, for example a screen or a charging port. These component failures are readily and immediately experienced by the user to be the proximate problem. Replacing the damaged or non-functional component would seem to be the obvious solution. Thus, a user comes to The TechKnow Space to have this problem remediated/repaired. Typically the doctor (our seasoned technicians) have no problem doing this.
Sometimes however, replacing/repairing components turns out to be an exercise in futility. Further diagnostics establishes the problem to be resident in the Main Logic Board. The replacement of these logic boards is prohibitive and best left alone. It’s time to move forward to a new device.
Bear in mind that these mainboard failures are a result of the initial damage to the device that prompted a visit to the repair shop even though it is not intuitively obvious.

iPhone 7, 7 Plus No Power, Wont Turn On Repair

The best thing would be to drop off your phone at one of our locations in Mississauga and Toronto & our technicians will be happy to assist you.

We will accept your iPhone 7 for diagnostics and do some basic tests to figure out the problem (it may take anywhere from 2-6 hours to do the diagnostic) and once the diagnostic is completed the technician will give you a call and explain you the problem and provide an estimate for fixing the problem.


When your iPhone 6 or 6 Plus won't turn on - bring it to TechKnow Space in Toronto or Mississauga for the fastest repair solution.If you are worried your new iPhone 6 or 6 Plus 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 6 or iPhone 6 Plus 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 6 or iPhone 6 Plus 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 6 or iPhone 6 Plus 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.

When I brought my iPhone 6 to TechKnow Space, I thought it was damaged beyond repair. With a bend so bad that the phone resembled a boomerang more than a smartphone, I held out little hope for repair. Not only did they advise me on my options, they fixed the phone so that it looks like new. This phone literally should have been a doorstop, but somehow they were able to fix it. Thanks for the great service!



iPhone 5 won't turn on Mississauga Toronto.You picked up your iPhone 5, iPhone 5C or iPhone 5S just to find that it is showing no signs of life? With trembling hands you are trying to push all the buttons, to no avail? Don’t worry.

As simple as it sounds, first try to plug the phone into the charger. If the iphone was out in the cold it could run out of power a lot faster then it normally does, or you just forgot to charge it! If that doesn’t work – try to press and hold the home button and the power button for 10 seconds, then release the home button, but keep holding the power button. This will hard-reset your iPhone.

If you’ve tried the above, but your iPhone still won’t turn on – you’ll need to bring it in to any of our convenient locations in Toronto & Mississauga and our expert technicians will diagnose the problem and will call you with an estimate on the repair.

This is my first review ever on Google and it goes out to this great establishment. A brief history of my problem. My phone died and would not hold a charge. It was plagued with a month of ever decreasing battery life. It detected the cord without an issue but I tried a couple more just in case, cleaned my charge port and tried a hard reset without any resolution.

I brought it to the Apple Store who told me it was not salvageable and that I needed to replace it and offered me a discount on my iPhone 5. It was the logic board they said.

Ash (owner I believe) listened to the problem with my phone and really listened without any assumptions. I left my phone with them and in less than 20 mins I was called by Ash to tell me it was fixed and that it was my battery
