iphone 3gs, intermitant after replacing the glass and digitizer

[CrannyT]

Just bought the 3gs, broke glass and replaced with kit. All went according to plan, however once everything was replaced, the display powered on, phone works, can hear it ring, but I cant use the touch screen. Any ideas?

Cable between chip and glass was disconnected. open it and fix it.

There are 3 cables connected the screen assembly to the logic board.

1. Cable #1 is for LCD
2. Cable #2 is for the digitizer
3. Cable #3 is for ear piece and sensor proximility

I think your cable # 2 is somehow loose/disconnected when you put press the top in.

Just open it and be careful this time to make sure everything is tight before close it.
