1. Networked Devices

You can connect your smartphones and other smart devices wirelessly with your Denon Receivers. The catch is, the receiver can detect the presence of your smart devices.

If any of your devices have Denon App running in the background or something similar, the receiver will most likely turn on. In such circumstances, you will have to eliminate the factors.


  • Locate the devices that have been connected to the receiver.
  • Make sure that the ‘Bluetooth’ is off in those devices if not necessary. 
  • Also, check if the Denon Connect App is running in the background. Close the app if necessary.

2. CEC Settings

CEC or Consumer Electronics Control allows you to control the receiver with one remote control. Any HDMI-connected device can control your Denon Receiver. 

Now, if your HDMI-connected device, for example, TV, PlayStations, Xbox, or other electronics is on standby, it can activate the receiver.

To solve this problem, you will have to manually shut down the CEC settings from your device.


  • Go to the settings of your TV or your device. And go to the ‘HDMI Settings’.
  • Search for CEC settings. Turn off the CEC if it is turned on.
  • Now, go to the settings of your Denon Receiver and turn off the CEC and ARC settings. 

3. Unwanted IR Signals

Your Denon Receiver can get triggered if you have accidentally used the remote. Now, in most cases, users have reported pets accidentally pressing the remote controls. 

In such cases, the Denon receiver turns on and off by itself. However, in another scenario, matching IR signals can also turn on the receiver by itself. 


  • Keep your remote controls in safe and isolated places when not in use.
  • Make sure that the window curtains are pulled before going to bed.
  • Do not keep other appliances with IR blasters in the same room.

4. Activation of Denon Protect Mode

Now, Denon Protect Mode is designed to be a safety feature for your receivers. It will turn on once the receiver senses any sort of malfunction in the thermal sensors.

In most cases, a dead sort in the speakers can trigger this safety feature. Once the feature is on, the display panel will start flashing ‘Protect’. 


  • Now, the remedy to this problem is to find the cause and eliminate the threat.
  • Closely monitor all your connections and speakers. Usually, when a speaker is dead, it will not work or will start buzzing. Fix that by taking it to a technician.
  • Even after fixing the problem, if your receiver malfunctions again, contact customer support for further help.
