Hi, The first clue is did both channels stop working. If so the it is a piece of equipment that stopped working. If only one channel is not working then try swapping things from right to left and see if the problem moves to the alternate channel when something is swapped. Just do one pair at a time though. For example both input cables from a phono. Both speaker sets. etc If everything stopped working then it may be as simple as a power cord (if it uses detachable ones) being loose or has come off. Possibly a fuse. Also it could be a bad outlet. Try plugging everything into another outlet.
IMO cables seldom fail without giving warning and like I said only in one channel at a time.
