Top of Touchscreen not working

[Cartel]

The top of my touch screen became unresponsive.
I can do the touch calibration but after that the top part still wont work.
When I press the back button it does nothing and I cant slide the menu down to restart or dim backlight.

My unit worked great until yesterday.

Its the JY-UM135N2

Very weird. I can calibrate the screen and it see's my touch at the very top but once I leave that page the top 10% wont work.
It only works on the calibration page.
Why would that be?
