  If your Denon Stereo Receiver's display is lit but no sound is produced, several factors could be at play. Check if the speaker cables are securely connected and ensure they are properly attached.

Why is the power indicator blinking red on my Denon DRA-37 Stereo Receiver?
- J
  Jeffery CollinsAug 25, 2025
  If the power has turned off and the power indicator is blinking red on your Denon Stereo Receiver, it could be due to a few reasons. The internal temperature might have risen, activating the protection circuit; in this case, place the receiver in a well-ventilated area. Alternatively, the speaker cables' core wires might be touching each other or the receiver's rear panel, also activating the protection circuit; check all speaker cable connections. You can also try turning off the power and waiting for the unit to cool down before turning it back on. If the issue persists, it is best to contact a DENON customer service center.
