Hello I was changing the screen on an iPhone XS max. Like a dumb *** I forgot to unhook the batteries and now the phone will not turn on and it smells the burnt. I really want to fix this phone as I’m trying to do this to make extra money and this one belongs to someone else. I understand it may take some fine soldering and I’m prepared to do that. I just need help troubleshooting to find exactly what part to change. From what I figured out so far I’m thinking I fried the power ic. Am I even close? Can someone with some expertise in the field please help? I really appreciate any input Thanks and have a great day!
If you want the communities help diagnosing your phones problem, you will need the following equipment. · Schematics diagram for the phone. · Board view software. · Multimeter. · Microscope. These are only for diagnosing the problem. You will need more equipment for the repair. I recommend trying another screen first in case the damage was only applied to the screen.
Did you use an aftermarket LCD screen assembly instead of the original design OLED assembly? If so, then a crease in the screen will short main voltage to ground and burn up the display connector. I did a video on this a few months ago. https://www.youtube.com/watch?v=D_PnL0KK…
I believe you fried your motherboard. Hate to say it but there’s not much you can do.
