Only backlight on the screen...
I have an iPhone 6 in for a screen replacement. I had two screen left, but i´ve had an issue with both.
First I tried the screens without reassembling the small parts (camera, LCD shield plate ect), and it worked fine.
When i reassembled the small parts it just have backlight. Works fine if I connect the old screen
Also: the phone will not turn on when the new screen connected. But if the phone is powered on and I connect it, I get the backlight..
This happend to both.. Can´t see any damage on the flex cables.
I´ve done alot of iPhone repairs, so I´m not a newbie :p
Hope someone can help me understand what happened/what went wrong :p
