  If the display is lit but no sound is coming from your Denon Stereo Receiver, there are several possible reasons: * Check that the speaker cables are securely connected. * Ensure the FUNCTION knob is set to a suitable position. * Verify that the volume control is not set to the minimum; turn it up to a suitable level. * Make sure MUTING is switched off. * Confirm that digital signals are being input, or select the correct input terminals for digital signals.

  If the display is not lit and no sound is produced when the power switch is on, it could be that the power supply cord is not securely plugged in. Check the power cord to ensure it's properly inserted. After turning the POWER switch on, try turning the power on with the remote control unit.

  If the display is not lit and no sound is produced when the power switch is on, it could be due to the power supply cord not being securely plugged in. Check the insertion of the power supply cord plug. Alternatively, try turning the power on with the remote control after turning the POWER switch on.

What to do if my Denon AVR-1906 Stereo Receiver display is not lit and the power indicator is flashing rapidly?
- D
  Debbie MartinezAug 27, 2025
  If the display of your Denon Stereo Receiver is not lit and the power indicator is flashing rapidly, it could be due to a short-circuit in the speaker terminals. Switch the power off, connect the speakers properly, and then switch the power back on. Another possibility is that the ventilation holes are blocked, or the unit is operating at continuous high power with inadequate ventilation. In this case, turn off the power, ventilate the unit well, allow it to cool down, and then turn the power back on.

Why are the positions of instruments reversed during stereo playback on my Denon Stereo Receiver?
- J
  James JarvisAug 30, 2025
  If the positions of instruments are reversed during stereo playback on your Denon Stereo Receiver, it's probably due to reversed connections of the left and right speakers or the left and right input/output cables. Check the left and right connections to ensure they are correct.

Why is there a howling noise produced when the volume is high on my Denon AVR-1906 Stereo Receiver?
- J
  Jacqueline PowersSep 2, 2025
  A howling noise when the volume is high on your Denon Stereo Receiver can be caused by speaker systems being too close together; separate them as much as possible. It can also occur if the floor is unstable and vibrates easily; use cushions to absorb speaker vibrations transmitted by the floor.

Why does my Denon AVR-1906 display not light up and the power indicator flashes rapidly?
- C
  Christopher WilliamsSep 7, 2025
  If the display is not lit and the power indicator is flashing rapidly, it could be due to: * Short-circuited speaker terminals: Switch the power off, connect the speakers properly, and then switch the power back on. * Blocked ventilation holes: Turn off the power, ventilate the unit well, and allow it to cool down before turning it back on. * Continuous high power operation with inadequate ventilation: Turn off the power, ventilate the unit well, and allow it to cool down before turning it back on.

  Holly GarciaSep 10, 2025
  If you're experiencing a howling noise when the volume is high on your Denon Stereo Receiver, it could be due to: * Speaker systems being too close together: Separate them as much as possible. * An unstable floor causing vibrations: Use cushions to absorb speaker vibrations transmitted by the floor. If your turntable lacks insulators, consider using audio insulators (sold separately).
