Hello Dave,
I had an AVP-S several years ago that had a similar problem. It was covered under warrantee so I sent it back to Harman in Massachusetts this was after Proceed closed its doors. There were some problems with power supply regulation and display ICs, which were replaced. This may rule out interference with another component as a cause.
The round trip took about 6 weeks; the only cost I incurred was for the shipping to Harman. Its best to contact Harman by phone because they seem not to read emails (assume thats how you contacted them.) I actually found them to be very helpful and responsive, and I believe they have worked through their issues associated with disbanding Madrigal and merging the service departments.
If you are beyond your warrantee period (5 years, I recall) they may be able to recommend a service technician local to your area.
