Hello all, So I received an iP 6plus the other day. Client brought it in for screen issues to another shop. It was powering on before he brough it to them, and after it was dead. I spotted long screw damage - Excavated a bit but all the traces where I was expecting a break look good. What do you all think from these picture?
Other than that - Looks like it had touch disease - Probably the screen issues he was having. Has a piece of rubber stuff stuck onto the chips to apply pressure and flux everywhere. I haven’t poked around there yet to see if anything is off. Looks like with my usb ampmeter - its pulling 0.9 then jumps between 0 and .9 over and over again during boot. No image on screen. What do you all think? Update - original photo
If a previous tech tried to repair Touch Disease and didn’t succeed, I would be concerned about excess heat spilling over to the CPU, bridges and shorts under and around the Touch IC’s etc. I would start at the beginning and check all the PMIC/BBPMU power rails to see if there are some obvious issues at the subsystem level. I would also check the RESET_1V8_L line to see if it is oscillating as well.
