after repair, display is not working anymore
Yesterday, I changed the display/digitizer unit because the original screen showed a grey vertical bar on the left display side. I worked accoring ifixit repair guide.
After reassembling, the display stays black, only the background lighting comes up. Beside this defect, the phone seems to work properly - it is recognized by itunes and i can flash/synchronize.
What I tried:
-I tried to reset (home+power) for several times
-I tried to reinstall firmware (6.2.1)
-I disconnected all non relevant connectors for testing basic function (i only left power button, display and battery)
-I reconnected the old display unit
But nothing helped.
Did I brick my iphone or does anyone have a hint, how to get the display working again? Many thanks in advance!
Is this a good question?
