Screen is on but black after assembly
i am really frustrated at the moment and i hope someone can help me in here.
I tried to change my girlfriends iPhone 4 Homebutton, everything went easy. I was really carefully to. After reassemblying the device, the screen now is on (i see a bit light(like an app with black background)). I tried to restart and reset the phone via itunes but did not help. Reassemblied a couple of times and worked very carefully. Stil no help. Screen goes out after a couple seconds. Pressing the powerbutton brings the "black lightet" screen back again.
What can i do? Please help me out.
Is this a good question?
