Unresposive touch screen - screen problem ruled out

Hi there,

I have come across a strange thing with the phone of my boss.

He told me from one moment to another the touchscreen became unresponsive.

I took the phone, dissassembled it, tried with another screen only with cables connected, no shielding bracket, worked. Then a cleant the socket and the plug with isopropanol of the original screen and tested it, still without the shield, it surprisingly worked. I reassembled the phone with the shield, switched it on, no touch again. I tried with the other screen assembled, doesn’t work. My ideia is the touch ic, isopropanol might help but after evaporating, the problem comes back. I don’t think it can be anything with the screen.

Any thoughts from you?

Thanks.

Tamas

check the connection on the board, ensure none of the connections are bent. Works with EMI shield off then when placed no touch-try backing off the screws by a 1/4 turn.
