Hi everybody!

I got used Garmin nuvi 780 - previous owner said unit just was flashing logo. So I got it to play with (for $10)
After charging overnight I can boot it! Everything works - I updated system, maps. It locates me on the road. Shows my speed. Perfect except of touch... It doesn't respond AT ALL!!!

I booted unit in calibration mode - it didn't respond to my touch of the dot...

I took it apart, reseated cables - the same.


Now I ran out of ideas... Is it bad digitizer? Do they fail?

Thanks for any help!
