Touchscreen not working even after touch IC replacements
Received an iPad Air 2 with water damage which didn’t turn on. I checked everything and removed/replaced the burned capacitors etc and now it turns on. Touchscreen is not responsive, so I reballed all 3 touch IC and it still doesn’t work. Any advice what else could be the problem before I spend $30 for the 3 IC that may or may not help.
There are 2 resistors (R4012 and R4013) I haven’t replaced yet and 1 diode (NSR10F40NXT5G) and could those be the culprit.
