[NTLK] Touch screen stopped working, digitizer cable looks great. Ideas?

[Ian Finder]

As an update: I was able to get the touchscreen to respond last night with
the unit stripped down, no bezel, holding all the pieces together. I have
hope it will continue to work when reassembled.

I'm going to try and get it put back together this weekend, restored, and
back on the road to it's rightful owner- who has been very patient.

Thanks for the advice!
