Hello everyone, I had a question and was unsure wether or not to open a new thread or append to a similar thread. Had repaired my iPhones like dozens of times in the past. My current iPhone6 Model A1586 had vertical stripes resembling white noise this morning; restarting didn’t help. I presumed a cable was loose, so I opened it up, unplugged and reattached all cables leading to the display. After that, I tried turning the thing back on and the stripes were still there. I repeated the process once (unplugging and replugging relevant display cables), but then the display stayed completely black. Since I did not order a replacement display yet, I first wanted to determine wether or not the display was broken or the phone itself. Several options: Some cable was about to give out, after opening up, the relevant cables power line broke completely.Something in the board broke, GPU or whatever.My attempt to fix it may have shorted something out on the board (either the display had a short circuit or the cables were inproperly reconnected.Something else. To determine wether the iPhone6 was still okay, I unplugged the Display completely and turned the phone on. I presume the iPhone should still start and vibrate once. The battery should still be about 86% full. What I then did was: I turned the iPhone off, unplugged the battery. Display was disconnected.Waited 30 seconds. Turned the side lever to ‘silent/vibrate’.reconnected the battery and tried turning it on.Plugged the power cord in. tried turning on again.Phone did not vibrate, while the side lever was on ‘silent’ Shouldn’t it at least vibrate with the display being disconnected? Am I correct to assume the board is fried? I would refrain from ordering a new display and buy an Android Phone instead, if the thing is no longer repairable. The phone was turned off during every step above, but I am not sure I may have forgotten to unplug the battery one time. What’s the worst that could happen unplugging and reconnecting cables while the battery is still connected (while the mobile is off)? Would it be possible to save the data somehow, if the GPU was fried or whatever? Thanks for any suggestions.
I finally managed to get it back working. Apparently the statement in another thread of the iPhone being able to start with just the mainboard and the battery was misleading. It stated the iPhone would still turn on, even if the display assembly was disconnected. Since the phone did not vibrate and not show any other signs when trying to turn it back on, I had assumed the mainboard got fried. After replacing the display, the phone seems to be able to boot without problems. Thanks again for your answers.
Hi It’s most likely the screen as the GPU failing is extremely rare But to confirm this I would try using it in a external display through airplay or a wired connection Some displays go bad on their own some need a drop overall they are extremely fragile Hopefully this helps Any questions please ask Thanks:-)
