Why is there no sound coming from the speakers of my Denon AVR-2308CI Stereo Receiver?
- S
  Steve BranchAug 21, 2025
  If your Denon Stereo Receiver isn't producing sound from the speakers, start by checking all the connections to your input devices and speaker cables to ensure they are secure. Verify that the input source selected on the receiver matches the device you're trying to play. Make sure the master volume isn't set too low; adjust it to an audible level. Also, confirm that mute mode is not activated by canceling it. Disconnect any headphones that are plugged in. If you're using digital inputs, ensure that digital signals are being input and that the input source is correctly set for digital input. Finally, check that the connectors assigned to the digital inputs match the settable input modes and adjust the input mode accordingly.

What to do if my Denon AVR-2308CI does not work properly when using the remote control?
- E
  Eric FrancoSep 1, 2025
  If your Denon Stereo Receiver isn't working properly with the remote control, first replace the batteries with new ones. Ensure you are operating the remote within the specified range and that there are no obstacles between the remote and the main unit. Check that the batteries are inserted correctly, matching the polarity marks in the battery compartment. Strong light, such as direct sunlight or fluorescent bulbs, can interfere with the remote sensor; move the unit to a location where the sensor isn't exposed to such light. Lastly, verify that the remote ID of the main unit and the remote control match, setting the Remote ID for the main unit to “1” if necessary.

  If there is no picture appearing on your Denon Stereo Receiver, start by checking the connections between the receiver and the monitor to ensure they are secure. Make sure the monitor’s input setting is correctly set. If the PURE DIRECT mode is activated, cancel it. Also, high definition (1080i/720p) and progressive (480p/576p) video signals are not down-converted, so set the player to interlace (480i/576i) signals.
