iPhone XR Screen Keeps Displaying Pink Pixels Randomly & Reboots.

So, pretty much as the title says. When I turn the phone on, it displays the apple logo, but sometimes it’ll turn pink, distort and it sometimes boots up to the start up menu… After a short while it might decide to become unresponsive and reboot the phone. It’s a constant loop.

Has anyone came across this before and if so, how do you go around diagnosing the problem? I get a feeling a simple DFU restore won’t fix it. It seems like it’s sustained impact damage and possibly ruptured something on the logic board. I can’t do soldering repairs yet, so chances are it’s a sell on item.

I’d like to know how to troubleshoot this issue though, cause you need to learn somehow.

Thanks,

Craig.

Edit: This is what it has looked like, it’s done this before and it has also pixelated and even moved the apple logo on the boot screen. Ironically the thing isn’t doing it now, but still crashes. This is clearly a board issue. Can you send me in the right direction as to how to diagnose the error or the failed chip etc. on the board? As I’m trying to learn this stuff for myself, thank you!

The above isn’t my image, but it’s looked exactly like that during bootup before. I’m also getting error 12 on the DFU restore on 3Utools.
