If your Denon CD Player isn't responding to the remote, the batteries may be dead. Try replacing them with new ones. Also, make sure you're not too far from the unit; try moving closer to the set.
What to do if my Denon CD Player displays “NO DISC” even though a disc is loaded?
If your Denon CD Player shows “NO DISC” when a disc is inside, it might not be loaded correctly. Try reloading the disc properly.
Why won't my Denon CD Player start playback?
If your Denon CD Player isn't starting playback, the disc might be dirty or scratched. Wipe the dirt off the disc or try replacing it with a new one.
What does “00 : 00” displayed on my Denon DCD-CX3 mean?
If your Denon CD Player displays “00 : 00” even with a disc loaded, it probably means you've loaded a disc other than a CD or Super Audio CD. Try loading a CD or Super Audio CD instead.
Why my Denon DCD-CX3 not outputting digital signals?
If your Denon CD Player is not outputting digital signals when playing Super Audio CDs, use the analog audio output signals instead. Also, ensure that the pure direct mode is turned off.
Why can't I play programmed playback on my Denon DCD-CX3?
If programmed playback isn't working on your Denon CD Player, it's likely the tracks haven't been programmed properly. Make sure to program them correctly.
