Wacky touchscreen on Cassiopeia A-20

I have a Cassiopeia A-20 that I obtained relatively cheaply, but with one catch: the touch screen didn't work quite correctly. Even after calibrating it a few times, nearly all of the screen surface has ~5mm inaccuracy, and one area near top right corner has a few centimeters of inaccuracy! I could live with the former, but the latter is driving me nuts. I considered just buying something more modern (and working), but with the price tags involved, I was barely able to afford this A-20, not to mention anything better, even used.

So, the question is: how can this be fixed? Of course replacing the entire touchscreen assy is out of question (look above), but I know that there are programs to fix it. The only problem is, the only ones I found are all for Palm OS. Are there any such progs for WinCE2? I'd greatly appreciate any help.

Don't think you're going to find a software fix for that problem. Sounds like the digitizer is shot. So yeah, replacing the LCD/touchscreen assembly is what would be required.

i think no such programs are available for wince, especially not for CE 2.0, at least i never heard about them,
palms have an advantage here.

you could buy another CE 2 unit quite cheap, maybe even a colour one ...

Emm...does anyone know which dgitizer chip is used there??Soldering in a new one may be chaeper than all, I think.

Erm....chip? The glass top is probably scratched to the point that it doesn't read stylus pressure reliably. May not be visible damage, but more than likely this is the culprit - particularly since the problem is worse in one corner.
