Moblion 4600 - unresponsive screen

[TCinPDX]

Problem here:
Mobilon 4600 screen decided it won't respond to clicks. I've tried resetting, recalibrating touchscreen; removing batteries and even removing ROM upgrade. Nothing works. Screen makes "clicking" sound but otherwise does not respond.
Any ideas? Any good places for repairs? I don't want to lose my trusty 4600!
Thanks,
TCinPDX

Sounds like a bad cable from computer to touch screen.
I have used these guys. My cost to repair was 101.56 including shipping to Hawaii. If you are interested, I have some used 4600s that are good except for batteries. Let me know if you are interested.
