Lcd wont turn on after replacement
before to start I want to specify that i've been changing iPhone lcds, batteries and whatever broken part for 3 years, and I never seen anything like that.
A customer gave me an unopened iPhone 6 with a cracked but working lcd, so, as always, I bought a replacement and went to fix it.
I want to specify that I use gloves and plastic tools to remove any part of any device, mostly for hygiene and security reasons. Oh, i've also done all software thing (restore, hard reset, win/mac, etc.).
I tried to use 4, yes, 4 different lcds (including an original one from another working iphone 6) and it just does not turn on, but itunes detect it.
I also tried to use another battery, but nothing changes.
On the motherboard, the lcd and front camera connectors does not seems damaged.
Do you have any ideas, i'm literally going crazy! Do you think that Apple will repair it (no Apple Care) if i'll perfectly remount all pieces?
