Need help troubleshooting Auto-On circuitry for LF-10

My brother gave me a Klipsch LF-10 Subwoofer and it has a problem in the Auto-On circuit.

If I switch the unit to On, then to Auto, it stays on even if there is no signal present.

If I switch the unit to Off, then to Auto, it stays off even if there is a signal present.

The final twist: sometimes it works perfectly, but not often.

The switch itself feels a little sloppy, so I plan to open the unit up and check the switch operation with a multimeter.

Does anyone have any other suggestions? Are schematics available?

For now, I just leave the unit on at all times.

Thanks in advance,

Jeff
