Why is my Denon AVR-550SD Stereo Receiver display lit but no sound is produced?
- A
  Amy LoganAug 16, 2025
  If the display is lit but no sound comes from your Denon Stereo Receiver, there are several potential causes: * The speaker cords might not be securely connected; ensure they are. * The audio function button may be in the wrong position; adjust it accordingly. * The volume control could be set to the minimum; increase the volume. * MUTING might be activated; switch it off. * If you've selected a digital input, ensure digital signals are actually being input, or select the correct input jacks.

What to do if active subwoofer (DSW-3L) LED flashes and no sound is produced on Denon AVR-550SD?
- E
  Eric WardAug 19, 2025
  If your Denon Stereo Receiver isn't producing any sound and the LED on your active subwoofer (DSW-3L) is flashing, it indicates that the protective circuit has been activated due to excess input or a rise in temperature. Set the power switch to the “OFF” position, wait at least 1 minute, then set the power switch back to the “ON” position. If the problem persists, unplug the AC power cord from the AC power outlet and contact your store of purchase.

Why is the display not lit and power indicator flashing rapidly on my Denon AVR-550SD?
- A
  Alicia HarrisSep 2, 2025
  If the display of your Denon Stereo Receiver isn't lit and the power indicator is flashing rapidly, it could be due to a short-circuited speaker terminal or blocked ventilation holes, or the unit is operating at continuous high power conditions and/or inadequate ventilation. First, switch off the power and ensure the speakers are properly connected. Then, make sure the ventilation holes are not blocked and allow the unit to cool down before switching it back on.

Why is the sound distorted on my Denon Stereo Receiver's active subwoofer (DSW-3L)?
- H
  Hannah RhodesSep 4, 2025
  If you're hearing distorted sound from the active subwoofer (DSW-3L) connected to your Denon Stereo Receiver, it might be because the volume level is too high. Try turning the volume adjustment control counterclockwise to lower the volume. Also, check if the sound is being distorted on the connected amplifier; if so, avoid amplifying the bass sound on the amplifier by lowering the amplifier’s bass adjustment control or volume.
