Pioneer VSX D1S audio hum

[johnrich]

I have this older, but wonderful, reciever and playing stereo LPS through the beast with some good OLD JBL and ALTEC Voice of Theatre Systems! The unit rocks, even as old as it is! LOL! It has started a small annoying hum in the audio in both channels, with all inputs. I am assuming this be casused in the power supply circuit. Any help would GREATLY be appreciated in trouble shooting this annoying problem. In advance thanks!

Do you have cable TV? Unplug the cable from the cable box- it should go away. If it does, buy an isolation adapter from Parts Express. Better yet, call your cable company and tell them to ground their feed, like the National Electrical Code requires.
