Why is there no sound coming from my Denon AVR-4800 even though the display is on?

  Lynn TurnerAug 12, 2025
  If your Denon Stereo Receiver's display is lit but no sound is coming out, there could be several reasons: * The speaker cords might not be securely connected, so ensure they are properly attached. * The audio function button might be in the wrong position; adjust it accordingly. * The volume control could be set to the minimum; increase the volume to a suitable level. * The muting function may be activated; switch it off. * Digital signals might not be input, so ensure digital signals are being input or that you've selected the correct input jacks.

What to do if the display is not lit and the power indicator is flashing rapidly on my Denon AVR-4800 Stereo Receiver?
- K
  Kenneth ThompsonAug 20, 2025
  If your Denon Stereo Receiver's display is not lit and the power indicator is flashing rapidly, 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. Alternatively, blocked ventilation holes might be causing the unit to overheat. In this case, turn off the power, ensure the unit is well-ventilated to cool it down, and then turn the power back on. Also, operating the unit at continuous high power with inadequate ventilation can cause the same issue; follow the same steps to cool it down.
