Why is the power indicator flashing rapidly and the display not lit on my Denon Stereo Receiver?
- S
  Sharon SuttonAug 20, 2025
  If the display is not lit and the power indicator is flashing rapidly on your Denon Stereo Receiver, it could be due to: * Short-circuited speaker terminals: Switch the power off, connect the speakers correctly, and then switch the power back on. * Blocked ventilation holes: Turn off the power, ventilate the unit to cool it down, and then turn the power back on once it's cooled. * Continuous high power operation and/or inadequate ventilation: Turn off the power, ventilate it well, and then turn it back on after it cools down.

  If your Denon Stereo Receiver produces a howling noise at high volumes, it could be because: * The turntable and speaker systems are too close together: Separate them as much as possible. * The floor is unstable and vibrates easily: Use cushions to absorb speaker vibrations transmitted through the floor. If your turntable lacks insulators, consider using audio insulators.
