Why does only the original LCD work?
Help! I've repaired dozens of ipad's and mini's and never encountered this issue!
Customer broke ipad mini digitizer and cracked LCD. Only half of the original LCD works.
After opening the ipad, I always, always, always disconnect the power before replacing the digitizer and LCD. (So shouldn't be a problem with the fuse or diode.)
But I've tried 5 new LCD's and none work! I started to think I had a bad batch that missed quality, but all 5??
This is the kicker.... I plug the original LCD back in and get the half broken display again. I've done this many, many times switching out LCD'S and still, nothing works but the original.
I can't get any LCD to work except for the original!
I have a streroscope, and I'm a very experienced microsolderer (12 years working in the aerospace industry).
I don't see that there is any charring of parts, all solder looks good (no pinholes, cracks, etc) all connectors are 100% intact.
3 of my LCD'S are from etech parts, 2 from ifixit. These are quality companies, not ebay or Amazon parts.
What could be the issue? The filter capacitor and diode test fine (from reading other message boards). I need help please!!
Is this a good question?
