Question about Harman Kardon AVR 300 Receiver
Getting intermittent breakdown in connection in all surround sound modes. Both DVD and satelite TV decoder audio connection is through coaxial. There are times that it works perfectly for days. On Dolby it start sounding like the voices are brubling, and on the digital to analogue modes, it gives a sort of a bgggggggg sound. Switching the amp off and on again, its perfect again. I checked all connections. Thought it may be a loose connection inside the amp?
Befor you go for bench time I would resolder all the board conectors for the ss prosesor board and preamp to amp board.

This is most likely a problem with the processing chip/system. It could be as simple as a bad connection at the chips or the chips are having problems internally. This is not a problem that is likely to be fixed without bench time and test equipment. You're going to need to get this unit to a service shop for proper diagnosis.
