No image on any screen after correctly replacing 5 SE LCD
Today I replaced a customer's LCD on their iPhone SE. After disconnecting the battery, the phone may have been on when the battery was disconnected, then removing the LCD (note, the LCD was not removed while the battery was connected), I have been unable to get any image whatsoever on the screen.
I've tested 5 total screens, original good LCD included, all of which display nothing after the phone was disassembled. The phone has been restored in DFU mode to no avail.
This does not seem to be a backlight issue as absolutely nothing is visible on the screen under any circumstance. Shining my iPhone 7+ flashlight at the screen from all angles results in nothing more than a black plane. I've tested every possible thing I can think of and am left with a brick of a customer's device.. Any clues on how I could proceed?
Es esta una buena pregunta?
