SQ-6 Processing butten does not respond any more

SQ SQ Troubleshooting
1

Since yesterday I have the problem, that on my SQ-6 the Processing button does not respond anymore.
I was preparing the scene for the concert of a Bluesband, and while doing the setup, I noticed,
that I had to press the Processing button increasingly more often, when I wanted to change back from Routing to Processing
At last the button was non-responsive. It does not feel like a mechanical problem, the ”press-feeling” is normal and not different to the other buttons.
After rebooting the mixer, the Processing screen is displayed and the green button LED is lit and as long as I do not press the Routing button, I can reach every processing screen.
I reinstalled Firmware SQ-6UPG_1_5_10r4132, but this didn’t change the behavior.

My questions now:
– do you think, this seems to be a hardware-problem ? (and who could fix it – the German distributor Audio-Technica Deutschland ?)
– should I try a real hardware-reset ?
– is there any possibility to program any other SoftKeyes to function as the Processing button ? (as a work-around)

Otherwise, I will probably have to protect the routing button against unintentional pressing (cover it).
I would then have to operate the routing function via the iPad if necessary.

Thanks a lot in advance

Good news about the SQ problem:
I had a concert with a cover band on 5 January and prepared the scene at home before, i.e. worked again with the SQ-6.
The behaviour of the processing button slowly improved again and finally became almost normal.
I.e. the button reacted more and more often to the pressure - possibly just a temporary contact problem due to a “speck of dust”…?
There were no more problems at the concert, of course I hope it stays that way now!
