Most common Denon receivers issues

If you can’t turn on your Denon receiver, disconnect the power and push + hold the “Direct” &”Stereo” keys while reconnecting the power chord. If you have issues with the audio, check that all chords are correctly inserted. For issues with controls, ensure the input setting on the Denon remote and TV match.


While most users have had a reliable and positive experience with the Denon receiver, a few individuals have faced issues with the receiver and required troubleshooting. In this post, we will be going through the issues Denon receiver users may face and the measures to troubleshoot them.

Problems When Turning On the Denon Receiver

When you turn on a Denon receiver, it has a microprocessor that sets up the audio and video settings for you. When the device is turned on, it may sometimes cut off because the microprocessor confuses the protective circuit, causing the Denon to shut down.

How to Fix the Problem

Disconnect the receiver from the power source, then simultaneously push and hold the “Direct” and “Stereo” keys on the front of the device while connecting the power chord back in. Wait for the front of the receiver’s screen to flash before releasing the buttons. This should reset and initialize the microprocessor, allowing the receiver to turn on without switching off.

Problems with the Audio

Denon receivers have a variety of hookups for connecting components, including iPod docking stations, RCA cable jacks, S-video inputs for linking an HDTV, and HDMI and USB ports. If a problem occurs, try to pinpoint the source of the problem.

If the receiver turns on and plays music from a connected iPod but you can’t get movies to play on the DVD player, the issue is most likely a faulty connection between the Denon and the DVD player.

How to Fix the Problem

Checking the chords connecting your audio-video devices to the Denon receiver takes just a few minutes. All chords should be securely inserted into their respective jacks. When using HDMI, USB, or S-video cables, check sure the plug is oriented correctly before inserting it into the port.

To troubleshoot speaker issues, use the remote control to switch the Denon to “Surround Sound” mode, then use the test function to listen to a white noise from each speaker attached to your system. If the sound skips a speaker, you’ve narrowed down the problem to that channel. Test the speaker cable between that channel and the Denon receiver.

Problems with Settings and Controls

Due to the receiver’s intricacy and variety of component links, all it takes is just one random touch of a remote control key to alter the receiver’s settings and perhaps prevent a component from working.

You may discover that the changer on your CD player is not controllable by the remote control of your receiver or that the DVD player shows no image on your TV if your children have been gaming and have forgotten to reset the input setting back to what it was before they used your device.

How to Fix the Problem

If you want to enjoy a movie with the DVD player, ensure the input setting on the Denon remote is switched to DVD. Likewise, if the TV input control is switched to a setting that isn’t directly connected to the Denon receiver, you won’t be able to see anything that is being played from any Denon-attached component. If the Denon receiver is linked to Input 1 on the TV, use the TV remote to return it to Input 1.
