Ok. First assumption has to be that the cable is ok ? Next two most likely
things are that something has happened to the amp's selection of digital in,
and a bad connector at the amp end - you tried a different source I think
you said. Some of these Denons select digital in automatically as a result
of sensing data on the digital input, but some have to be manually selected.
I'm not suggesting for one minute that you don't know how to use your
equipment, but I would say that it's very easy to get confused with amps
that have manual analogue / digital input switching, and to get the wrong
mode selected. I can sometimes sit puzzling over the right setting for 5
minutes or more - and I mend the things for a living ... !!
As far as bad connectors go, if they are not regularly disturbed, then it's
fairly unlikely, but still a possibility. Worth just pushing on the socket.
Beyond this, you're probably not going to get very far, without test
equipment. My next move would be to 'scope what's coming out of the coax,
then to follow it into the amp. Does your DVD have an optical out that you
could try ? I'm sure that the Denon will have an optical in. One final thing
that you might try, if you're OK going inside the amp. Many of these AV amps
are constructed using a mother board, and then plug-in daughter boards for
input processing, digital processing etc. I have on many occasions had the
connectors on these boards go a bit iffy. It would be worth just gently
pushing down on, and rocking any boards connected to one another in this
way. I have to say that 'genuine' digital processing faults of this nature,
are pretty rare.
I have service manuals for several common Denons on DVD, but unfortunately,
not that model, so I am not able to be more specific.
