Home Theater Questions? Ask a Technician for Answers ASAP
Hello and sorry you're having problems. Offhand this is typically caused by a processor failing within the receiver- and it can work with no rhyme or reason. However in order to determine that, I need to ask you for some more information.
1) How long have you owned the Denon for and when did the problem occur?
2) Does the issue occur when the volume is turned up, and is the top of the receiver noticeably hot?
3) Have you reset the processor yet?
4) Have you removed, re-stripped and reconnected all speaker wires yet?
These are all possible things that could cause this, but I would need to know what you've tried to determine this. It can be caused by a bare strand of speaker wire touching the chassis, the unit not having enough ventilation on the top (at least 2-3"), the speakers being too low of an impedance (in case the issue occurs when it's hot, or when the volume is turned up). It can sometimes be cured by resetting the processor (let me know if you've tried that), and beyond all of these things, it's a failure occurring within the receiver that will become worse until the unit no longer functions and requires service through Denon. Let me know what you've tried and we can proceed.

Thanks for the reply. Your speaker wires sound good- since binding posts are clean and would rule out the chances of any stray wires touching the chassis. Also, if heat is not an issue, then this would indicate the issue is either a hardware issue, or a processor glitch. You would want to first try the steps below to reset the unit to factory defaults (NOTE:The receiver will need to be setup as if it were new).
I am pulling up these instructions right now.
To do this, disconnect the receiver from power, then plug it back in.
While off, press and hold "Tuner Preset +" and "Tuner Preset -" on the front of the unit itself (not the remote), while pressing power once. The display will then start blinking and then release the Tuner Preset buttons. If the display does not start blinking, then shut off the receiver and start the steps from the beginning. Once the display flashes, and the Tuner buttons are released, the processor will be reset.
These are outlined on page 238 of the manual at the link below:
