Question about Denon AVR-4806 Receiver
The most likely cause of this is a failing transistor or two in the pre-amp section. There should be a pair of transistors in what is caled a dif-amp setup. These are the most likely candidates for replacement. They may be in a single 5 pin package. If you can, try hitting some of the transistors with freeze spray when the problem occurs. If the problem goes away, the last part hit with the spray is the likely faulty component.
