Fix iPhone 6 Black Screen, Wont Turn On, Becomes Unresponsive

Problem 1: iPhone 6 becomes unresponsive, screen turns black and won’t turn on

Hi there. I have an iPhone 6, 64GB, and recently when I tried to turn it on the screen just displayed a blue-black screen with a stripe down the side of it. I thought this was strange, as the phone had been in a bag padded all around with clothes and no damage had been done to the bag. And so I tried to turn it off and turn it back on, which did not work. The screen remained completely black and unresponsive. I then tried the trick where I hold down the top button and the home button, which didn’t work. I even tried plugging it into the computer to wither restore the phone or figure out something else I could do, but as this is a relatively new phone and I hadn’t gotten the chance to sync it to my computer yet, iTunes told me that I would have to enter the passcode on my phone before it could access the phone’s data– however, my phone was still unresponsive.

All of this happened a couple of days after I updated the phone, and had been noticing a few quirks, like apps closing by themselves and the phone restarting. I might also add that shortly after the screen went black, I noticed that the top right-hand corner of the screen was really hot, and every time I plug my phone into an outlet to see if it will work again (it hasn’t), that part of the screen heats up again, which leads me to believe that the phone isn’t completely dead or broken. Any way you can help or advice you could give me would be greatly appreciated! — Rain Yeatts

Solution: Hi Rain. Your phone either suffers from a defective screen issue, or won’t turn on at all. To know if it’s the former, try to check if your phone does any of the following:

  • vibrates when restarting
  • makes sound for incoming messages and/or notifications
  • rings when you call your number
  • shows any light indicator
  • displays the Apple logo when connected to a charger

If the device shows any of the indicators above, the problem must be isolated to the screen only and thus, screen troubleshooting must be done accordingly. Below are some of the things that you must try:

  1. Make sure that your screen isn’t cracked, chipped, or damaged.
  2. If you have a case or screen protector, take it off.
  3. If you’re wearing gloves, take them off.
  4. If you’ve put any stickers over the screen or sensors, peel them off.
  5. Make sure that your screen is clean.

Sometimes, updating an iOS device via DFU Mode helps in fixing rare screen issues due to a software glitch. If you haven’t tried this yet, here are the steps:

  1. In your computer, close all active apps.
  2. Open iTunes.
  3. Turn off your iPhone. If you can’t turn it off normally, let the battery drain to 0% so the phone powers down on its own. Charge the phone for at least an hour without attempting to turn it on.
  4. Connect your iPhone to the computer via USB cable.
  5. Press and hold the Power button for at least 3 seconds.
  6. Press and hold the Volume Down button on the left side of the iPhone while continuing to hold the Power button. Be sure to hold both Power and Volume Down keys for 10 seconds. If Apple logo appears at this time, repeat steps 5 and 6. Apple logo should not show at all.
  7. Continue to hold Volume Down key for another 5 seconds. If the Plug into iTunes screen is displayed, repeat steps 5-7. Plug into iTunes screen should not show up.
  8. You’ll know that your phone is in DFU mode if the screen remains black. Your computer should then tell you that iTunes has detected an iPhone.
  9. Follow the on-screen steps in your computer to do a full recovery.

If the phone won’t turn off, won’t load DFU mode, or has become totally unresponsive and does not do any of the things above, there must be a hardware issue that causes it. It can be a defective battery, a malfunctioning power management IC, or some unknown hardware fault. You should contact Apple for support.

Problem 2: What to do if previously working iPhone 6 got dropped and stopped working normally

My iPhone 6 is not turning on after I dropped it, it was a very small height less than 0.5 meters. I try to turn it on and nothing happens but when I put on the Lighting cable it tries to turn on and the Apple logo shows up for 5 secs and turns off, and again it turns on until the Apple logo with black background shows up and again turns off, by itself without touching anything. (When it is not charging even the Apple logo doesn’t show up and doesn’t try to turn on). More info: Battery was at 90%, Also nothing happens when I try to charge it with the PC (USB cable) and it doesn’t show up in PC at USB connected Devices as it usually should. Thanks! — Altin Mullaidrizi

Solution: Hi Altin. If the symptoms you mention were not present before the phone got accidentally dropped and was working normally, your device must be damaged internally. This means that there’s an on-going hardware malfunction causing the issues reported here. Since we don’t support hardware troubleshooting and diagnostics, be sure to call Apple so their technicians can take a look at it. Misuse like accidentally dropping a device or water damage automatically voids any manufacturer warranty so any repair with Apple may not be free.

Problem 3: iPhone 6 won’t turn on after screen replacement

My fiance has this iPhone 6. The screen ended up cracking but could hold a charge perfectly fine. After a while the crack grew and and she couldn’t use the numbers on the lock screen to open the phone so we had a new phone screen put in and it worked great for about a week and no troubles then charged and all. the phone died in the living room and it will not turn on or respond at all even plugging it in. we’ve tried everything we could look up?? Also I went back to the store that replaced the screen and there was nothing they could do but send it to a guy to work on the motherboard. So that’s are issue thanks for the help! Also could they have damaged this? — Tony

Solution: Hi Tony. If initial hardware checks showed that a motherboard repair is necessary, as recommended by the shop, it means your phone cannot be fixed by doing software solutions in your end. If your point in contacting us is to see if there’s still anything that you can do other than go through motherboard repair, we say it depends on the problem. However, since a shop has already checked the phone physically and found out that there may be a motherboard problem, you should follow their advice. The most that you can do on your level is to perform limited software troubleshooting and nothing more. These software troubleshooting includes installing updates, restore, and update via DFU Mode. We don’t know the real score but there’s a chance the first repair to replace the screen did not address all issues. Remember, your phone was physically impacted which resulted to the screen cracking. It’s possible that the force of the impact may have affected other components inside so even if the screen has been replaced, the other damaged parts remained. This is not an isolated case for physically impacted devices so doing software troubleshooting is almost pointless to begin with. Obviously, you can’t fix a hardware issue by changing some software settings. Unless you are familiar with the inner workings of an iPhone 6 hardware, how to diagnose their issues and how to replace parts, do-it-yourself repair will most likely leave with a worse phone than with a working one. We say let a professional take a look at the hardware so they can tell you if the phone can still be fixed.
