Sony TA-E77ESD Preamp Not Working

I set up my system after moving, but when I turned the preamp on it buzzes and the volume control returns to 0 after being advanced.  I've moved many times and never had this happen before.

Any ideas as to what is causing this?  If not self-fixable, any recommendations for audio service in Lake County, Florida?

Thanks for any help.

If it were me, I'd try operating all switches and controls a few time to see if it might be a poor switch contact. If that doesn't work, take the cover off and look for any connectors that may have come loose during the move. Sony typically uses a lot of connectors between circuit boards.
