Pop, Fizz, Crackle

The sound system began popping, fizzing, and reporting the dreaded F61 error and shutting itself off again this morning. Blasted intermittent error! It will probably clear itself again if I disconnect and reconnect the six pairs of speaker wires, but I don't want to have to keep doing this every few weeks. The cables are not exactly located in a convenient spot -- you have to remove the cable box and VCR and then pull the unit out far enough to get at all of those wires.
