Default Re: EXC3188-FG31 Touch Controller Eegalaxy

you always need to calibrate touchscreens.
on large screens you may have an eeprom on the cable itself,
but usually it's in the software - your problem is going to be finding out if the calibration software is hidden inside the unit or external.

also - clean all the flux off - specially under the chip between the balls.
