Broken/loose digitizer cable

After years of solid use, last night my Pandora started to act erratic to input. Touching the screen would make the arrow jump all over the place. I rebooted and had the same behavior. I calibrated the touchscreen and that makes the input not work at all when done. And sometimes, I cannot get out of the calibration tool because it's no longer registering inputs.

When I have a terminal open and I move the screen, I can see the xterm losing focus, so it thinks I touched the screen?

What can I do? It seems a hardware issue; can I fix it myself (I am handy with electronics but I guess I'm asking if I need a new flatcable or if it is easier than that)?

Also; how do I disable touch input? Everything works fine with the nubs but sometimes I get many ghost clicks which prevent me from doing work; I think if I disable touch, that will be solved.

A depressing day for my trusted Pandora :)
 
Sometimes the screen bezel pops out at some side and presses on the touch screen. In that case just reseating it should fix the problem.
 
Well; the bezel does not seem to be popped out and I resetted a 100 times (also because I cannot get out of the calibration tool if the input is not working; I tried pressing all buttons and I didn't have anything else that can do ssh at that moment).
[doublepost=1492421616,1492421120][/doublepost]It seems that when the digitizer does work, it only works in the middle of the screen and very erradic (like the mouse pointer I try to move at that time is 1+ cm removed from where I would expect it and it 'wobbles' aka it moves 5mm back and forth while moving it); when I 'have' the mouse pointer moving with the pen and I move it close to the edges of the screen, stuff will really mess up aka generating input clicks and movement randomly all over the screen. It takes a lot of randomly tapping and moving the arrow with the nubs to get it back to 'normal' after that.
 
And that happened all of a sudden? I will try that. Maybe you both are right... It just happened so suddenly while I was working on it and I definitely did not touch the lid, but maybe it slipped a nanometer.

Try loosening the Inner lid. I had the same a while ago. It happened because the inner lid was pushing against the digitizer on the sides of the screen.
