Hi folks
I switched on my big blue today and as I was playing through Xmen the left channel dropped out, tried wiggling wires around the amp and nothing, put in another a board and the sound is fine so amp and speakers are fine, decided to hook the bad A board up to another cab and still have no left channel, i looked over the A board and can't see any broken traces or cold solder joints, now the strange part is when i put it all back together both channels worked, i thought great fixed, i switch the other cab on just to test again a few hours later and the left channel is gone again, any ideas?

The A board has a digital volume circuit that for whatever reason needs a reset from time to time. Boot the board while holding down the volume-down button.
