I have an Onkyo system. It has worked perfectly for over a year. I turned it on recently and a very loud hum was coming from the subwoofer and surround sound speakers. I unplugged the subwoofer and the hum diminished was still there.

I have not changed any of the settings or wiring configuration or how the various power cables are plugged in.

Please help!
