What should I do if my Denon AVR-987's subwoofer isn't producing sound?
If your subwoofer isn't producing sound, here are some things to check: * Make sure the subwoofer’s power is on. * Ensure the subwoofer’s initial setting is set to “YES.” * Verify the subwoofer’s output is properly connected. * Check that the subwoofer’s channel volume level is not set to “OFF.” If it is, turn the subwoofer’s channel volume level up.
Why is sound only coming from the center speaker on my Denon Receiver?
If sound is only being produced from the center speaker, you may be playing a monaural source (TV, AM radio broadcast, etc.) in the DOLBY/DTS SURROUND mode. When playing monaural sources, select a surround mode other than DOLBY/DTS SURROUND mode.
Why is there no sound coming from my Denon Receiver, even though the display is on?
There are several reasons why your Denon Receiver might not be producing sound: * The speaker cables may not be securely connected, so ensure they are properly connected. * The FUNCTION knob may be in the wrong position, so switch it to the correct one. * The volume control might be set to the minimum, so turn the volume up. * MUTING may be activated, so switch it off. * There might not be a digital signal being input, so properly select a digital signal input source.
What to do if no sound is coming from the surround speakers on my Denon AVR-987?
If you are not getting any sound from your surround speakers, check the following: * Ensure that the surround mode is set to a mode other than “STEREO.” * Make sure the AVR-987 is in a well-ventilated place. * If the power indicator is blinking red, the set’s internal temperature may have risen and the protection circuit has been activated. Turn off the power, then wait for the set to fully cool off before turning the power back on. * Check the connections of all the speaker cables in case the core wires are touching each other or the AVR-987’s rear panel, activating the protection circuit. * If the problem persists, the AVR-987 may be malfunctioning.
How to fix a Denon Receiver when the display is not lit and no sound is produced?
If the display is not lit and no sound is being produced when the power switch is on, the power supply cord may not be plugged in securely. Check the insertion of the power supply cord plug.
Why is nothing displayed on the monitor connected to my Denon AVR-987 Receiver?
If nothing is displayed on the monitor, consider these possibilities: * The AVR-987’s video output terminals and the monitor’s input terminals might not be properly connected. Check that the connections are correct. * The monitor’s input setting might be wrong. Set the monitor’s input selector to the terminals to which video signals are connected. * The PURE DIRECT mode might be set. Set a surround mode other than the PURE DIRECT mode. * If a player is connected with a component terminal and the TV is connected with a video terminal (yellow) or S-Video terminal, down-conversion is not possible for progressive video signals. Make the interlace settings on the player.
How do I troubleshoot no DTS sound on my Denon AVR-987 Receiver?
If no DTS sound is being produced, check the following: * Ensure the DVD player’s audio output setting is set to bit stream by making the DVD player’s default settings. * Confirm that the DVD player is DTS-compatible and use a DTS-compatible player if needed. * Verify that the AVR-987’s input setting is set to “AUTO” or “DTS.” If it is set to analog, change the setting.
What does “CHECK ANTENNA” mean on my Denon Receiver in XM mode?
