No Schematic, does anybody know the number of the decoder ic or is it ttl and possibly a dry joint or cap causing the problem, i was about to cut the 2 caps off the volume pcb as a ceramic could cause this..any ideas?
Kind regards

I have the same problem. Does anyone know how to solve it? I'm not practical.

Rotel digital volume switch is not the same as generic 3 pin switch, + 0 -, strip, clean wipers and pads WD 40 not silicon Q20..i have heard the new Q20 is non silicon so it wont turn to gue, move the 3 wipers a mm outwards, assemble and 100%.
