  If the display of your Denon Receiver isn't showing anything and the power indicator is flashing rapidly, this could indicate a few issues: * The speaker terminals may be short-circuited. Turn off the power, ensure the speakers are correctly connected, and then turn the power back on. * The ventilation holes might be blocked. Turn off the power, allow the unit to ventilate and cool down, then turn it back on. * The unit may be operating at continuous high power with inadequate ventilation. Turn it off, ventilate to cool it down, and then turn it back on.

  Ryan LeeSep 5, 2025
  If the display isn't showing and the “ON/STANDBY” LED is flashing rapidly, it could be due to short-circuited speaker terminals, blocked ventilation, or the unit overheating from continuous high power usage with poor ventilation. To resolve this: * Turn off the power. * Ensure speakers are correctly connected. * Switch the power back on. If that doesn't work, turn off the receiver, ensure it has adequate ventilation to cool down, and then turn it back on.
