  If your Denon Receiver isn't responding to the remote, the batteries may be dead, or the remote might be too far from the unit. There could also be an obstacle blocking the signal, you might be pressing the wrong button, or the batteries might be inserted incorrectly. Try replacing the batteries with new ones, moving closer to the receiver, removing any obstacles, pressing the correct button, and ensuring the batteries are inserted with the correct polarity.

  If the display is lit but no sound is coming from your Denon Receiver, check the following: Ensure the speaker cords are securely connected, the audio function button is in the correct position, the volume is not set to minimum, MUTING is off, and digital signals are properly input if a digital input is selected. Adjust these settings as needed.

  If the display isn't lit and there's no sound from your Denon Receiver, the power cord might not be securely plugged in. Ensure the power cord is properly inserted. Also, after turning the POWER switch on, try turning the power on with the remote control.

  Ronald ThomasAug 17, 2025
  If the display is not lit and the power indicator is flashing rapidly on your Denon Receiver, it could be due to short-circuited speaker terminals, blocked ventilation holes, or the unit operating at continuous high power with inadequate ventilation. Turn the power off, properly connect the speakers, and then turn the power back on. Also, turn off the power and ensure the unit is well-ventilated to cool it down before turning it back on.
