Xmon Off / Stuck in Mute
 

Hi Friends, any help with this would be appreciated.

After a power shortage our Xmon has been stuck in Mute and won't come off.
I also hear a soft ticking noise when speakers and Xmon are on. When turning the main pot on D-control ticking noise gets louder.

When i turn on the unit MIDI RX button lights up shortly and Mute enables.

D-control says Xmon off.
D-control doesn't show any Xmon firmware, can't update Xmon either. (error 1)

Tried to power cycle while pressing reset button, no luck.

Any suggestions? Not looking good. :-( Thank you!
