Hi enrob, It was there a spamGPT answer that point to a faulty ribbon cable and warning you to be careful when opening the device to check this part. I mention this because this is not totally dumb. Nevertheless I believe those answer are as useful as a picture of the Pope in white puffy jacket running away from the police. You've already explore the old forums so you may already know most of what wiz know on this common issue, most digitizers ends up developing a touch fault. Sometimes its the ribbon cable but sometimes it's not. Think someone explored another track on this but I dont remember he found a solution. Good luck.
