Today I noticed there is a 5-10mm wide multicolored spot on the touchscreen. If the spot is touched, it changes size, as if there is wet spot between some layer. Anyone know what it could be? I tried taking photo of it with the screen turned off. The spot is above and to right of the glare from the overhead light.
@George Olive
Please check if something is holding up behind and squeezing to the screen?
Can you send a video to the technician for confirmation?
@RasPad Support I didn't think anything was holding up behind the screen but I took the pad apart, moved wires, put it back together, and the spot was gone. My temp hdmi cable must have out of place. Thanks for your help!
