Lithoss

I'm having an odd problem with my lilliput 619GL-70NP that i havent been able to find any help on (yes i searched)

If i touch the left side of my screen its perfectly accurate, but as i touch farther to the right of the screen, and eventually the far right edge, the screen reacts farther and farther off on the x axis. so once i get to the right side, its off by a good 2 inches. but in the middle its off by say 0.5 inch. the y axis is fine.

what makes it worse is that it seems to go in and out of this problem. if i calibrate it while its operating 'correctly', the next time i turn on my car it will be off. or maybe just later in the same trip (10 minutes, 60 minutes etc). so i calibrate when its 'off' and it goes back again at some later time.

its not drivers because i just did a full rework of my carpc with different mobo and everything and it has the exact same problem.

my bezel seems to be fine. i havent touched it since i first installed it a few months ago and it worked fine for the longest time.

could my touchscreen be on its way out the door? anyone else had this specific problem?
