Hello, I have a Disgo 8000 and the touchscreen no longer works. It can't detect my finger or anything so I did the factory reset but now I can't get past the calibrate part - the crosshair (the little circle you need to press) just goes around the screen. I tried to touch the screen, getting the crosshair but to no luck. It just keeps jumping around. Is there anyway to fix this? Please and thank you if anyone replies!
