So 2.5 years later there’s still nothing on a fix for this? We’ve recently been experiencing the same issue and I can report the same general condition:
I’m already on latest firmware, nothing relevant on the diagnostic tool/logs. As well as it has (as of yet) only affected the GLD-80 input banks and seemingly randomly in groups of 4 (sometimes one group, sometimes all groups, etc.).
We have a few peripherals connected via DSnake but I don’t know those details offhand. One thought from a ‘consultant’ was a possibility that something nondeterministic in the startup sequence might somehow be throwing a wrench in things (which would account for the reboots BUT wouldn’t account for my last experience). The last major failing (2 days ago) I got it all showing correctly after a few reboots but then during use, all the screens eventually blanked out (ours have been going the no-text route as opposed to all-blocks). Nothing else seems to be impacted (all back-lighting colors, I/O control, faders, control screen, etc. works – I can also connect in via the iPad app (which was handy)). Examining the board briefly yesterday, everything was displaying normally (so I haven’t had a chance to try any of the reset tricks suggested earlier).
Any updates from the A&H team (or anyone else with input on what they’ve done with their problem units) would be appreciated!
