The DENON 3805 is a wonderful old receiver, other than the fact that it's a nightmare.
This is now my father's receiver. He called earlier tonight and said the audio is gone again. Now, my dad is not able to multitask anymore and it is difficult for him to follow instructions.
He has sound from the DVD/BD player but NOT from the Cable box. Every once in a while they press a button on the remote or front of the unit and POOF! No more sound. There is some crazy complicated setting about this particular receiver where it disables incoming Digital signals or that function is turned off and no amount of button pressing brings it back.
Does ANYONE have ANY IDEA how to fix this?
Again, everything is fine when he switches it to DVD. Perfection.
I have worked with him on this before. It never seems to be a Zone or Speaker A, AB, B thing.
No matter where it is, there is no sound.
We've pressed I.MODE a hundred times. You name it, we have pressed it.
Going to auto it ends up in Analog because it is not detecting any digital sound. Right now the Cable box is Optical Out to the Denon and the Cable box is transmitting Dolby Digital.
Connections are all fine.
We've never been able to fix this properly (it happens every four or five months). It just fixes itself as he presses buttons over and over and then suddenly it comes back. But tonight I was on the phone with him for THREE HOURS! Nothing. We just don't know the right sequence of buttons to press and I have studied the damn manual the last hour.
I need a miracle because I won't be down to North Carolina for another seven weeks.
Attached image is from mom's iPhone. It's the best she can do and it is a miracle she was able to take one at all.
DIGITAL should be lit all the way on the left side. Not ANALOG. The Cable channel was on DEXTER and should be Dolby Digital, not DOLBY PLII cine. For whatever reason, the receiver is just not seeing the digital signal.
