4S no display after screen replacement. Old one works?
I have a very unique situation.
I have replaced my iPhone diplay assembly 3 times.
EVERY time, it won't power on or work.
EVERY time I plug the old display in, and it works fine.
I have bought 3 different displays from 2 different vendors.
Any clues?
I've done several iPhone 4 displays.
Am I missing something?
Is this a good question?
