Hey guys,


So I am having an issue with my Denon AVR-3312Ci. It plays fine for a while then all of a sudden it starts "clicking" inside the amp and I lose the sound from the center channel. It will then "click" again and sound back and then back and forth.


The only thing I have changed is my TV stand and I added banana clips to all speaker wires. My new TV stand has about 4-5`` of clearance from the top of the receiver to the bottom of the next shelf and the sides and back are open. The only differance from the old one is the old one had likely about 8-10`` above the receiver.


Does anyone have any experience with this issue? I am thinking it might be overheating but that is just a guess. The receiver seems pretty warm.


Thanks for any help!

You mentioned adding banana clips for the speaker wires..

Check closely your connections, any little wire strand can cause a short, shutting off the audio..

Check both @ the AVR and loudspeaker..


Just my $0.05... 馃憤馃槈

Did some investigating tonight. When I wiggled the positive connection on the back of the receiver for the center channel it would click on and off. I redid the bananaclip connector but issue continued. I took the banana clip off and hooked it up without the clip and still get the clicking but have not lost center channel sound yet. It clicks off and on in a split second. Almost seems like a connection issue on that terminal in the receiver but not positive. I really hope I can fix this as there is literally nobody within a 12 hour drive that can fix this...

This is my guess as well. It seems when I lift up on the positive connector at the back for the center channel it clicks back on when off. Although, I have been using it the last 3 hours and no clicking at all, maybe a bad connection.


Hopefully issue resolved as I am not sure how I would get a loose connection inside fixed, I am a horrible solderer.

I am having what seems to be the exact same problem with my AVR-3312CI. I had to move my receiver slightly to check the position of a cable the other day and noticed a click. The center channel immediately stopped working. I wiggled the binding posts and the center channel started to work again. This has happened two or three times and now nothing will make the center channel work. I have removed and reset the cables, reset the microprocessor, swapped speakers and cables.



For whatever reason it seems that the magnetic contactor switch is not kicking in for the center channel. Does anyone have any idea on how to fix this? If not I will have to take the receiver to be serviced as it is now out of warranty (1 year refurbished warranty). I hate to hand it over and not have any control over how much this is going to cost to fix. Would be great to be more knowledgeable about this specific problem so as not to get hosed on the repair. Anyone else have any thoughts?

Bump, still have not figured this out. I have the receiver completely apart now and the connectors are soldered straight to the main board. Emailed Denon and can not buy entire board as one piece, have to have component that is broken fixed/replaced.

Anyone have any thoughts I could try to fix this before finding someone to send it away to?

same problem, same solution

My 3312 has been clicking for several months as well. (3-4 yr old, A4L, has worked fine so far). Then recently I noticed: no center and no rear right/left. No test tone out of these channels. Called support. Reset unsuccessful. Had also recently updated firmware and installed banana plugs, uncertain if connected or not. Then I read this thread, disconnected banana plugs for center channel, dropped the unit front slightly, and all channels are back. The clicking does sound like a magnetic trying to open or close a connection, maybe. No expert.
Summary: Drop it lightly, check again.
Thank you.

Same problem here. 3312 I bought open box from Best Buy two years ago (got the 4-year extended warranty, which I have a feeling I'll be cashing in on at some point). In the last couple months, the sound has started cutting out to the center and rear channels occasionally. I've noticed it accompanied by a clipping sound a few times. Haven't made any connection changes with the wiring. Use banana clips for the front speakers only; bare wire to center and rear channels. Anyway, lifted the front of the receiver and dropped it a few times. It's working again, for now... so another [temporary?] fix for the lift and drop solution. Thanks for the idea.

I had the same issue and took it to local service center. They said it's bad HDMI board. There was no part available to order or another 3312CI to replace so Denon sent 3313CI refurb under warranty. It's hardware issue, resetting microprocessor or reconnecting cable didn't help.

I am having the exact same issue. A rapid clicking noise and sound in center channel goes out. If I switch the receiver off, center starts working again for a moment and then right back out. If center channel does stay on for a bit, if I wiggle the receiver even slightly, it goes out again.

I can confirm that after turning the receiver off, lifting the front up half an inch and dropping it back down and then turning it back on, all of my channels have worked for the last six months straight.

I've had the same problem; pushing down on the top rear of avr near the HDMI output area fixes the problem for a while.

Hi,


Yesterday i got the same issue with my 3312, I lose the center and rear channels. The AVR starts clicking randomly and sounds goes off and on for those channels. Not it seems those channels dont come back on at all any more. (lifting the AVR a bit doesnt help for me either)


Since this thread started in 2013 I wonder if some of you know what is causing this? I contacted my local dealer and explaining the problem they think its a faulty processor unit (because the problem occurs with 3 speaker channels).


Now im not technician but when i hear that they might have to replace the processor I think of very high repair costs (if the replacement parts are still obtainable). So im hoping this is not the case.


So if any of you know what is causing this issue please let me (us) know.


thanks!!

I've recently started to have the same issue with my AVR-3312ci where the FR and Center channels cut out altogether. There isn't any clicking, and I've tested cables, connections, etc. but it seems to be something internal as when I semi-forcefully pickup and set the unit down, it resolves the issue for a few days until it starts again. If I just leave the unit on and don't change inputs, it keeps working fine, but if I power it off or change inputs, the channels have a high tendency to cut out, and has only gotten worse the last few weeks.

I just sent an email to Denon to see what they say but not very hopeful that they'll be willing to do anything as the unit was purchased in 2012 as a refurbished unit. Unfortunately, Washington state only has a single service center that only deals with products they've sold, and is 5 hours away anyway.

The Drop: A Fix for All Problems

Well Guys,

It is incredible that in this world of sophisticated electronics that picking up the AVR and dropping it will solve this problem. Incredible, but true.

After hours of going through the menus, resetting the microprocessor, reading the manual, doing a hard reset, etc., I read this forum and tried dropping my AVR-2312.

No ****. IT worked.

Thx AVSForum members.
