I was programming my GLD80 in my home pre-gig and had the touch screen become absolutely unresponsive. Even the buttons to the right of the screen had no effect. I did not wait more than 30 seconds then I simply cut the power. It rebooted, recovered where I was in my programming and worked the rest of the evening.
Hi John S.
This is the same problem I had with my previous GLD. Sent it to repair, got it back, and the same happened again. No rescue for the mixer both times (showstopper). Then i got a new board from the dealer, which is the one I have trouble with right now…
Best of luck to you 
Personally I am looking towards the Roland M-480… Sick and tired of all the trouble with my GLD, and i use it just by myself, this is not even a rental-mixer… The new one has been out on three gigs so far… But i have to say: the mixer performed on this weekends gig, in spite of the error message. So i was home free, though with an elevated heart-rate
