Why does my Denon AVR-487 Receiver power off and the power indicator blink red?
- J
  John LoweryAug 17, 2025
  If the Denon Receiver's power indicator is blinking red and the power has turned off, it could be due to several reasons. The internal temperature of the unit may have risen, activating the protection circuit; in this case, place the receiver in a well-ventilated area. Alternatively, the core wires of the speaker cables might be touching each other or the receiver's rear panel, also activating the protection circuit; check all speaker cable connections. As a last resort, the receiver may be malfunctioning, in which case you should turn off the power and contact a DENON customer service center.

  If there is no sound coming from the subwoofer connected to your Denon Receiver, start by checking if the subwoofer's power is turned on. Then, verify that the subwoofer's initial setting is set to "YES". Ensure that the subwoofer’s output is properly connected. Finally, make sure that the subwoofer’s channel volume level is not set to "OFF", and if it is, increase the volume.

  If no sound is being produced from the surround speakers on your Denon Receiver, it could be because the surround mode is set to "STEREO". To fix this, set the receiver to a mode other than "STEREO".

  If your Denon Receiver's display is lit but no sound is produced, there are several possible causes. Ensure that the speaker cables are securely connected. Also, check that the INPUT SELECTOR knob is in the correct position. Verify that the volume control is not set to the minimum level and that MUTING is switched off.

  If you are only hearing sound from the center speaker on your Denon Receiver, it may be because you are playing a monaural source (like TV or AM radio) in the STANDARD (Dolby/DTS Surround) mode. When playing monaural sources, select a surround mode other than STANDARD (Dolby/DTS Surround) mode.
