After a reboot, my touchscreen suddently stop working.
This is how I solved it. Big thanks to Tablet_Collector and NicolasG for pointing out how to solve it.
I followed the GUIDE here:
1) first I measured the voltage on those pins. It was 18.36 V (far different from the 15V that it was supposed to be).
2) I soldered a DIODE ( Silicon Diode 1N4148 - 75V 150mA 4.0ns ) as shown in the picture above.
3) Checked again the voltage and it was 15V
4) Last I isolated the whole thing.
here a picture of the mod:
and after the isolation:
But this time I have to say it was not an easy mod! The pins on the board are really really small and it was not easy to solder the diode properly... Plus at first I put the diode the wrong way...
Anyway now I have the touchscreen back, full working.
