Hello All, I am having a issue with a iphone 5 screen replacement Im doing for a friend. She just bought a replacement screen and tried doing the repair herself. She has done them before and never had a issue but this time it didnt work. After she replaced the screen with the digitizer the phone turns on but the screen stays black. I have reseeded the lcd cables and still nothing tried power cycle and still nothing unless im doing something wrong I dont what else to do.

Detach your iphone battery, also, attach the battery and try to turn up the phone.
