iPhone 5 Black screen after screen replacement
I replaced a iPhone 5 screen for a customer the other day. It worked fine when it was picked up, but a day later they returned it with a black screen. The phone seems to start up when plugged in to charge and vibrates when muted/unmuted, but the screen stays black. Whats puzzling is that it doesn't seems to start when I only use the power button. I can turn it off by holding power button and slide the bar, so the touch seems to work.
Heres what I've tried so far...
Replaced it with the original broken screen.
Replaced it with several new screens.
Disassemble and assemble the phone.
Replaced the power button flex.
Put the motherboard in a new iPhone 5.
Nothing helps. Hopefully someone can enlighten me. :)
