So here is my problem....
I have a Sony Jutebox CD payer hooked up to the Denon and I also have the DVD player hooked up to it to. I have the Denon hooked up to a speaker selector for the house. We have speakers in lots of rooms and you select Kitchen, Bathroom, Patio, etc.
Usually, I just select CD hit random play on the CD and select a few speakers around the house and it works (although I have had problems with the speaker selectors in the past, but I'll save that for another post). Anyway, now if I try to do this I get nothing from the speakers around the house. HOWEVER, if I can get the house speakers playing music, if I use the DVD player.....which is fine, except I can only play one at a time and that's a pain for parties and it should just work the way it used to, right?
Here's what I can tell you:
I have the CD hooked up via regular audio cables (you know the the kind with red and white end plugs). The DVD is connected via optical. When I look at the receiver it shows ANALOG for the CD player, but DIGITAL for the DVD player. Also with the DVD player the "lock" lights up, but it doesn't with the CD player.
Any help would be appreciated. I've poked around the settings to see if I could solve this riddle, but I give up.
Thanks,

Hello,
Its not that problem, however, a good technician always go back to the basic.
first is to check the all the connection.
second, project the error source.
third, test the socket connector maybe fault in it(grounded or if this not the error, maybe you have to split the cable connecting in parallel to the input speaker.
else, you have to check the circuit board . thats the worse problem and it need more highly qualified tech.

Hi,.
With the indulgence of the others...
If I understand your problem right:
1. CD works only in Speaker A (but not in Speaker B);
2. DVD works on either or both A/B;
3. CD will work if plug into to VCR input but selector must be of another source (not VCR).
A couple of suggestions:
a. pls try doing again the reset as ginko has suggested but make it a bit longer, i.e. unplug it from the mains for a couple of hours;
b. since you have remove most of the wiring, why dont you try switch A & B. make the family room speakers the B while the speaker selector the A;
c. hook the CD (only) using the RCA cables (red/white) nothing else;
d. play any CD music and go through the paces of selecting source, speakers, surround/hall/theater/etc as troylove11 has suggested.
This would be now a simple setup, 1 source (CD) to 1 output/speaker (the family room) via the Denon. Try different settings. If the CD plays normally then, without changing any setting nor powering it off (but with volume level all the way down), remove the family room speaker wiring and replace it with the wires to/from the speaker selector.
the idea is to determine which is the real issue, the Sony, the Denon settings/hardware or the speaker selector.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
have you tried my suggestions?
Hi again,
It would seem that you have tried most if not all of the possible actions. Here are a couple of more ideas and pls bear with me if it may try your patience:
1. based on your postings, it would appear that only the logic section of the Denon has an issue. Either that or you simply have a loose connection or a cold solder inside the Denon. This would be the result of when you tried and it worked but when you moved the units back into their position, things went haywire again;
2. on the logic section since you have tried the hard reset (unplug from the mains), have you tried the soft reset? This is better explained in page 39 of the user's manual that ginko has provided a link to;
3. notwithstanding the probable messy hookup, try the simplest connections on both the CD and DVD, both using RCA cables outside of the systems regular location (probably on the floor or on a spare table). connect your A speakers, however, for the B speaker, try installing a pair of spare of bookshelf speakers not your speaker switch. Try the system again. You can even try tapping on the Denon to determine if indeed there is a loose connection or a cold solder while playing a CD with the Denon switched to speaker B.

I think your set's components and cables must be checked one by one thoroughly.
Perhaps you may have someone with tech experience to assist in checking resistance and continuity of every cable used to interconnect speakers.
You must inspect everything with calm and better initialy setup your system.
Can you supply the model of the CD player in question. I read the post but do not believe I seen it mentioned.
Thankyou.
For a failure like this, with no settings changed prior to it happening. Then add in the inputs not working as they should and I would have to agree with some of the others and say your input board although not fried, certainly has issues.
Try this as a test...
Hook the CD player to the Amp using the other optical cable. Check the side of the cable carefully these are directional for best signal quality. Normally have an arrow pattern somewhere on them.
Connect it to OPT2 in and use the DIA to set it to CD Player
Plug in a set of headphones and check the signal is getting as far as the AMP. If not, check that the DIA for the CD player is running in 44.1khz mode (not 48khz)
After your last test run, I am more convinced then ever it's the input selector board causing the grief. The board uses a custom IC to allow all the inputs to be used then switches them internally within that IC when you make a selection on the front panel.
If that IC is failing, then it is quite possible for the signals to go awry.
It may not even be the IC failing (in a sense) but more the contats between the PCB and the IC are not in good contact. A dry joint so to speak. Problem is that custom IC will have around 100-200 pins (legs) on it. Even a small amount of corrosion will cause the solder to not have a good enough contact (same as the battery in your car) It's touching, but not enough for the signal to pass through.
Before it gets worse, or fails totally, my only suggestion is to get it to your local Hi-Fi repair centre and have them do a diagnostic on the board. In this case I do not mean your local TV repairman, but an authorised service agent who will have access to all the tools required to do the job properly. If the problem is caught now, the cost will be minimal compared to later.

Could possibly the mainboard broke. overload of speaker output without a reducer.
Sounds like a selector setting change. If you are 100% sure that when it was working correctly the setting that was use, you are using it now then I would suggest getting the manual and check all settings. Surround Sound and different kinds of hall, SS, theater, etc can change the sound and what speaker plays when.
Leave unplugged from power for a while and plug it back.
Do the unplugging to reset the receiver. check that is no muted and all the obvious things also replace rca cables, even if it is rather unlikely that both channels wires broke at same time. test the receiver on differnt cannels.
Your receiver should also have a funcion to direct audio , check that is set to rca cables output, refer to manual for this.
If the receiver is muted, and is not a matter of settings, then it is possile that the board or the pre-amp is gone in this case you may need a service
Here is the manual
AVR-3801_ENG
Some of the problem may be due to some misconnection, however it seems there are far too many issues to be just a matter of configuration settings and connections. If you never get sound on all output then it is likely an amp problem ( probably blown). If you have many weird behaviours, and you are sure they does not depend on your connection and settings, then it may be a firmware problem. The firmware image for Avr3801 is made available from Denon only to authorized service centers.
In this case you will probably need to have the device repaired from a reair center.

Question: if the RCA cables weren't working then I wouldn't get ANY audio at all right? But I do get audio in the family room, but not via the whole house speaker selector (and again, the speaker selector does output audio from the DVD player). I would think that means the audio cables are okay.
Nevertheless....I did the following:
Unplugged the Amp for about 1 hr, no change.
I then unplugged the audio cables from the CD player and found another optical cable and used that (and assigned it properly in the Digital In Assignment-DIA). I got no audio at all that time.
I thought maybe it was a bad optical cable, so I unplugged the CD and plugged in the DVD player. I left the DIA alone and got no audio at all from the DVD player. Then I changed the DIA to reflect the change and now I get audio again in the family room and again in through the speaker selector.
Any help would be appreciated.
Also, for output I setting I only see Coax and optical. I tried coax and
ALSO, as I remember now, the reason I didn't use the optical cable before when we set this all up was because I couln't get it to work right with the amp, which is why I went with regular audio cables.
That said, I WAS getting audio from the CD to the Amp and to the speaker selector, it wasn't until now that it stopped out putting the sound to the selector. I have the spaker selector being fed by surround speakers B. And I have the output selected to A + B and both A and B lights come on the display, but the selector doesn't seem to actually get the audio, while the other surround speakers do.
Again, why would it just stop working?
Thad smile!
So here is my problem....in a nutshell, my amp has stopped outputting the CD jutebox to surround speakers B, but it still outputs music from the CD to other surround speakers. When I play a DVD however surround speakers B does get audio. I have my whole-house speaker selector being fed by the output of surround Speakers B, so this is why this is a pain. Now I can?t get music in my dining room, patio, bathrooms, etc.
This was working properly then all of a sudden just stopped working. There were no changes made to anything, but it just went from working to not working. All else with the amp seems to be working fine. The speaker selector is outputting audio (again from the DVD), so I don?t believe it?s the speaker selector. Also, I am getting audio out of the CD in the family room and the amp seems to be working fine otherwise.
The CD was hooked up (it?s now totally unplugged due to all my testing [see below]) via regular audio cables (the ones with a red and white plug). I never was able to get the CD jutebox to output via the optical, not sure why, but can?t plug it in via that. It has no other outputs. The DVD is output to the receiver via optical cable.
In trying to fix the problem I have done the following tests:
Unplugged the Amp for about 1 hr to ?reset? it, no change.
I have the speaker selector being fed by surround speakers B. And I have the output selected to A + B and both A and B lights come on the display. I changed this to A only, to B only to A + B, I got nothing for each test.
I just messed around with it quite a bit just now and I am getting just lots of weird stuff. For example. I plugged the CD player in VCR1 and it plays the output of the CD when I select ANYTHING, except VCR. So if I select TV, tuner, VCR2, etc, it will play the CD, but if select VCR it will not. Now the DVD won?t play either! I just shut everything off and will test the DVD again later, but it seems that only one of them works at a time now.
Argh, I hate this!
Can someone help? Please only the most expert of experts!

I have been through the manual, a lot. The setting we use is 7 ch stereo and that's what I use when it is working and also what I am using now that it isn't working.
Also, like I said it was playing the CD via the VRC input when I selected anything BUT VCR. Does this mean the board is fried?

Also, I'm sorry, but telling me to check the manual and check my settings is not the type of expert help I thougt I was paying for.....
what does "project the error source" mean?
A. I will leave it unplugged all night as I'm worn out now.
I will run more test tomorrow. It freaked me out these eve when I plugged in the CD into VCR and it would output when I selected VCR2, TUNER, TV, etc. But, oddly, when I selected VCR is did not play at all. Funny thing too is that it would output all the way to the dining room, so go figure.
Then the DVD wouldn't play if the CD was plugged in. I'm really afraid the board is toast. I hope it's magically working tomorrow.
I'm afraid you might be right about the mainboard being broken. I plugged in the CD into VCR and it would output when I selected VCR2, TUNER, TV, etc. But, oddly, when I selected VCR is did not play at all.
What is a reducer / what problem does it seek to prevent/solve?
I think I have narrowed down the problem....here's what I did:
I unplugged all inputs 'cept for the DVD, used optical cable, checked the DIA and it was correct. Got no output at all. Tried every setting for surround mode, nothing on any setting.
Next I unplugged the DVD player and plugged in the CD player (with audio cables, not optical) into TV input. Got output from the CD player all the way to speakers B. It only output when TV was selected, it no longer plays the CD when Tuner is selected as it was last night.
I plugged the DVD into the amp with audio cables, not optical, just line out and now outputs all the way to speakers B. (I have now unplugged even the DVD video and having it go just directly to the TV.)
So, can you tell me where the problem lies? To me it seems it's an optical input issue. Would that require a whole new board? Or a smaller repair?
ALSO and further, Micromaster said I might have overloaded the speaker output because I don't have a reducer. Do you think, I need one? Ideally I want to set this up so I don?t fry the receiver, as we do have lots of speakers in the house. In actual fact, we never have plugged in all the speakers because or speaker selector is not big enough, only outputs to four rooms. I thought (originally) that since a room doesn?t have a left and a right speaker, that two rooms could share a selector (i.e., kitchen and dining room would go on one selector, one being the ?left? and one the ?right?, meaning both would be on as a pair, which was fine with me). But I have never been able to plug more than one speaker into each selector. I have even replaced the speaker selector recently and this one is doing the same thing. Your thoughts?
Anyway, thank you Benimur for doing the diagram and actually reading all my troubles, not just shooting off a quickie reply, much appreciated.
For Mark_Webber: My CD player is SONY CDP-CX250.
Oh boy, so I thought I was done and moved everything back to where it belongs (physically) and here's late breaking news:
The CD (I plugged it, with audio cables, not digital) back in the CD spot and it didn't output to surround speakers B. Then I unplugged from there and into VDP and it DID output to surround speakers B. Then I unplugged from VDP and back into CD did output to speakers B.
So whatever it is, it is not confined to the optical portion of the board.....great. Does this mean a whole new board?
