Thread: help needed to diagnose touchscreen problem

OK, here's the deal. My 7" Lilli monitor works fine, but the touchscreen seems to have given up the ghost. Nothing is obviously broken, I've tried all the USB ports, uninstalled and reinstalled the touchscreen software, and checked and rechecked all the connections and ribbon cables inside. I've done the 5v fan mod and it was working after that. No wires seemed to be loose on either side of the USB controller, the 4-wire flat ribbon wire going to the touchscreen itself seems ok, and I've not done anything at all to the front end of the screen.

Is anyone willing, for a reasonable fee, to diagnose and/or fix it for me? I'm losing patience and want to give it one last shot before chucking it and buying a new one. I also have little time to give it and what I have hasn't seemed to help!

I'm willing to ship it and pay for your time/trouble/expertise.

I've just about wrapped up the carpc prior to installing, and this is the last glitch I needed.

Thanks to anyone who can help. PM, post here, or email me at donald.j.davis@gmail.com
