Hello all. I've had a month long problem with my iphone. It fell down the stairs a month ago and the screen went white with blue lines. I read online and found out the lcd screen was damaged and ordered a replacement. I read online and replaced the screen myself. Then a week ago my phone fell again. I opened it up and saw that one of the cables (the #1 tabbed cable) came out. I put it back in and the phone worked perfectly. Then 2 days ago my sister dropped it while playing a game. now the screen works perfectly, but when i go to use the phone and slide to unlock it, nothing happens. When I receive a phone call I can't slide to accept the call. When I hold the power button to turn the phone off, I can move the slide bar to turn it off but it doesn't turn off. I reopened my phone again, and all the cables seem to be in place. Anyone know what can be causing this? My digitizer screen and my LCD are perfectly OK, with no scratches, blemishes nor dead pixels. EDIT: I have tried multiple reboots and restores, to no avail.
