Hi, I had my Ipad 1 for over a year and never had an issue until recently. The ipad wont let me swipe to unlock or to power down actually none of the touch function is working. I did the hard reset, i restored from backup and restored to original settings but still no go. It worked in the morning then my wife cleaned the screen with a solution she thought was windex but it was actually pinesol. Could that damage the touch sensitivity of the screen? I have screen protection on it but i removed it, not fixed. I dont know what else to do, right now im waiting for the charge to die out hoping that it will reset something within the system. Any suggestions, besides sending it in to get repaired?
