Select an input that is not connected, for example select CD with no cables going to the CD input on the backside. Will you then hear equal humming on both channels? If so, the amp stage is ok,
and the problem lies in the signal level circuitry.
Open the cover and use a plastic (insulated) stick to touch suspectible cables and components. When the sound returns, you've found the cause. Resolder or reseat the component/cable/card.
Use the insulated stick, NOT your fingers!

I was able to fix this issue by opening up the receiver, removing the circuit board that the power button and speaker selector knob contact, and then reseating that board back onto the circuit board it was connected to (the one with the majority of the control buttons). This completely resolved the problem. The power button works again and the audio does not drop out anymore.

There are bad solder connections inside the receiver that are causing the protection circuit to kick in. This is a simple resoldering job and should only cost the labor rate at a local service shop.
