Chosen Solution
Hello everyone. A few days ago, my iPhone had an accident that caused the screen and most of the upper portion of the phone (i.e. the front facing camera and earpiece) to shatter. To be more detailed, the cause of the cracking was a result of one of my headphones being wedged up against my phone and pushing against the it until the regions described above cracked. As a result of this, the screen was left mostly black (i.e. no light/color) in the bottom left, right, and upper right portions of the screen. The upper left portion, along with some of the bottom left of the screen had been left with the “rainbow lines,” which I discovered through prior research to be a result of a broken digitizer or LCD (this is not the part I am concerned about; the “rainbow lines“ can also be seen through a former ifixit post such this My iPhone 6 has lines and black spots all over the screen). As of yesterday, my phone was fully able to be tracked via Find My iPhone, received notifications (as evident of the vibrating of my phone), and I could feel the haptic feedback as a result of the phone asking me for my password. This leads me to the current predicament I am in. To be brief, yesterday I was taking screenshots using the home + power buttons to see if the on-screen flash that normally appears would somehow show up in the damaged “rainbow line” portion of the screen (it did not). After doing this a few times, the phone suddenly shut off (in that the rainbow lines went away and the phone became untraceable, failed to receive notifications, etc). So my question is if my phone would be fixable? I have a lot of photos and contacts that I would like to back up (something that I have regrettably failed to do since this October past). I know I will need a screen repair and that that is not an issue, but I am more concerned on whether my phone can be fixed to turn back on and allow me to back up my data. I tried charging the phone earlier and felt the top portion of the phone grow warm (which is normal; it also was just faintly warm and not scalding hot), something that I hope is a good sign that it can be salvaged. My current hypothesis is that the phone somehow short circuited as a result of the screen crack but I am honestly not 100% certain. Thank you for any help you can provide!
Your broken screen likely caused a short. The most likely is a short on vcc_main. There are a lot of components that can short that receive power from vcc_main. You will likely need to find a repair shop that does micro-soldering to fix your phone. Given your description I would say its pretty unlikely you have done irreversible damage to your phone which is the good news. If you have a shorted component you will have to clear this short before your phone will power on. You also should not try to charge the phone until you resolve the issue so you do not cause any further damage to the phone.
No u most likely dont have a short or any other nonsense like that follow the guides and replace the screen and u should be fine… that would be the first thing for anyone to try as the first step. If that doesn’t work then report back here be careful about not causing additional problems though like long screw damage etc…
