What to do if the Denon DRA-395 Stereo Receiver display is not displayed and the “ON/STANDBY” LED flashes at a high rate?

  Katherine SmithAug 8, 2025
  If your Denon Stereo Receiver display is not showing and the ON/STANDBY LED is rapidly flashing, it could be due to a short circuit in the speaker terminals. To resolve this, switch off the power, properly connect the speakers, and then switch the power back on. Another potential cause is blocked ventilation holes or continuous high-power operation leading to overheating. In this case, turn off the receiver, ensure adequate ventilation to cool it down, and then turn it back on.

Finally, verify that the batteries are inserted properly, with the < and > ends in the correct orientation.
