My Denon AVR-790 spontaneously switches between Stereo DVD

Customer Question

My Denon AVR-790 spontaneously switches between Stereo DVD mode (with no audio) and 5-ch Stereo DVD mode (WITH audio). I hear physical clicks as it switches from one mode to the other even as I do nothing, while audio goes on or off with each click.
I have also learned that I can tap the front panel of the AVR to cause a switch between modes.
What is the issue, and how to get this fixed?

Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. In order to assist you, I need to ask for more info.

1) Does it do this on all source settings (Aux, DVD, Cbl/SAT, etc.)?

2) When did the issue occur?

3) Have you done a full reset of the processor yet?
