Hello,
I dont know if it is a good place to ask this but I am going to give it a shot.
There is a resistive screen for the HTC Tattoo. The owner removed the sensor plastic off the screen and accidentally wiped a substance off the screen (the part with the sensor plastic off). Now when the plastic is put back on, the screen does not respond to touch.
What was this substance?And can this be repaired without changing the digitizer?
