A little background first:
Sounds used to play, but a little scratchy sometimes, before sitting in storage for a year.
MCR ribbon cables are new.
It has an MCR adapter for a switching PS
Voltages are fine, and the self test reveals no errors. The sound test seems to silently run through each sound, and the yellow led on the PCB does not flash or anything.
So, I'm thinking it's the MCR2 dual power amp board, but I don't really know how to verify this.
Any tips?
Thanks
