Why no sound from surround speakers on Denon Stereo Receiver?
If you're not hearing sound from your surround speakers, the surround mode might be set to “STEREO” or “DIRECT”. Change the setting to a surround playback mode.
Why is there no sound from the surround back speaker on my Denon Stereo Receiver?
Several settings could be causing this. First, check if the surround back speaker’s power amplifier is assigned to the correct channel. Also, make sure the surround back speaker setting isn't set to “None”. Verify that the “Parameter” – “Surround Parameter” – “SB CH OUT” settings are not set to “OFF”. Finally, ensure that the surround mode is set to a mode for 6.1- or 7.1-channel playback. Check the setting and change it as necessary. Set to something other than “None”. Please set “Parameter” – “Surround Parameter” – “SB CH OUT” to settings other than “OFF”. Select a surround playback mode.
Why no sound from center speaker on Denon Stereo Receiver?
If you're not getting sound from the center speaker while playing a monaural source (like TV or AM radio) in “STANDARD” (Dolby/ DTS Surround) mode, change the mode to something other than “STANDARD” (Dolby/ DTS Surround).
What to do if no picture appears with HDMI connections on Denon Stereo Receiver?
If you're not getting a picture via HDMI, first, double-check all HDMI connections to ensure they are properly connected. Next, verify the HDMI input setting on your Denon Stereo Receiver. Finally, make sure the HDMI format settings on both your player and monitor are compatible.
Why does no picture appear on my Denon Stereo Receiver?
If you're not seeing a picture, it could be due to faulty connections between the Denon Stereo Receiver and your monitor. Also, the connection terminals on the Denon Stereo Receiver and the monitor might not be compatible. Check the connections and ensure that the monitor output terminal is the same type as the input terminal used.
What does 'Code? [ ]' mean on my Denon Stereo Receiver in SIRIUS mode?
If “Code? [ ]” is displayed in SIRIUS mode, it means the selected channels are locked. Please insert pass word (4 digits) into “[ ]”.
What does 'INVALID CHANNEL' mean on my Denon Stereo Receiver in SIRIUS mode?
If “INVALID CHANNEL” appears in SIRIUS mode, it means the channel is not present. Select another channel.
What does 'ANTENNA ERROR' mean on my Denon Stereo Receiver in SIRIUS mode?
If you see “ANTENNA ERROR” in SIRIUS mode, it means that the Sirius Tuner is not connected, it will be broken. Check that the connections are correct.
What does 'CHECK SR TUNER' mean on my Denon Stereo Receiver in SIRIUS mode?
If you see “CHECK SR TUNER” in SIRIUS mode, it means the Sirius Tuner unit isn't connected. Verify that the connections are correct.
