Denon AVR-X3300W behaving strangely.

Hello there. I've got a an issue with my Denon AVR that I was hoping someone here might be able to help with.
Every now and then the AVR will make a really loud popping sound but the sound goes through the speakers, it's not the physical AVR that makes the sound. This sound can be incredibly loud. The weird thing about it is that when it does make this noise it launches the Audyssey setup screen. I've tried running the Audyssey setup but this hasn't stopped the issue. I've tried new HDMI and speaker cable to see if this helped; it didn't.
I've tried with the sub on and off/disconnected, this made no difference. It doesn't matter what the source is, they all do it.
It's not an issue I can record to show you as I can go for hours of watching something with no problem but then it will do it over and over with no warning.
As far as I can tell it's not an over heating issue, the AVR is well ventilated on all sides and doesn't feel hot to the touch, plus I'm yet to see any kind of warning signal.

I'm a bit stumped, can anyone offer advice or a fix please?

Have you tried (1) Disconnecting from the network, e.g. could it be signal from a device on the network with Audyssey app on it?

(1) Have you tried switching off MultEQ completely in the AUDIO settings?

I would try a factory reset in the first instance. You can save your settings first.

Resetting factory settings​


Perform this procedure if the display is abnormal or if operations cannot be performed.
Various settings are reset to the factory default values. Make settings again.
Ope Resetting X2200

Turn off the power using
Power Button
.

Press
Power Button
while simultaneously pressing TUNER PRESET CH + and TUNER PRESET CH -.

Remove your fingers from the two buttons when “Initialized” appears on the display.


Before restoring the default setting, the “Save” function of the web control function can be used to store the various settings of the unit. link
However, account information for network content and information on registered favorites cannot be stored.

I've tried turning all settings relating to Audyssey off and on and I've tried disconnecting the ethernet cable from the AVR but nothing has helped so far. I did have a weird thing happen earlier today, the power light started flashing to indicate wrong phase on a speaker, I ran Audyssey again and it says all my speakers are in the correct phase so I'm not sure what's going on there, I haven't changed the speaker wire configuration at all, it's been the same (other than replacing the speaker wire recently but I did each wire one by one to avoid confusing myself which is too easily done for me hahaha) since I bought the AVR when it was released, what, two years ago or more? At one point I was pretty sure that the sub was the issue as when I disconnected the the sub cable from the AVR it seemed to fix the issue for a week but then it randomly started again, almost like a software cascade failure or something. I even tried blowing dust out of the unit with my airbrush set to a low P.S.I. to see if that was an issue but it made no difference. This has been a persistent issue since late December but it seems to be getting worse over time.
I had considered that maybe there is an intermittent fault with the 3.5mm plug that the Audyssey microphone plugs in to as I can't find any other information online regarding why Audyssey would cause this issue.
Another thing I've noticed: the problem seems a lot worse when I'm using a DTS setting, it's still present with Dolby (I use mostly Atmos or DTS:X, preferring DTS:X) but it seems to be roughly 50% less frequent on a Dolby profile.

Interesting. There could be a short inside one of the speakers. It's a long shot but it could be worth disconnecting some of the speakers and trying it.

E.g. watch a film in 2.1, if it still does it, try a different two speakers for the 2.1 and see it does it again.

Of course, as Gibbsy says, a full reset may do the trick, fingers crossed!

Did you have any luck solving this? I have started to have exactly the same issue with my Denon AVRX3600 and I am looking for solutions! Many Thanks.

I have just started having a very similar problem on my AVRX3300. Also interested in a solution !

Most instances have happened when running a BD or DVD, but this morning I had an occurrence while I was just looking through the menus - a loud crackle on the sound and it switched to the Audyssey setup menu.

Hi DickB,

No solution identified yet unfortunately. Can't find any rhyme or reason to it. It can go a few days without issue, then suddenly become problematic again. At the moment, it looks like I am going to have to use the Richer Sounds six year guarantee to solve the issue :(

Have you also had issues with the receiver occasionally going into protection mode when it is powered up? (power light blinking every half a second).

I will certainly let you know if I find any more information on a cause and/or a solution to this issue. Please do the same

Thanks Danny - yes, originally the problem was the receiver switching to Audyssey setup, but now it more frequently goes into protect mode exactly as you describe. I read somewhere that when this happens there are Denon error logs available, but I don't know how to access them.

I did a factory reset as described above and that didn't fix it. I get the problem even if there is no connected input device powered on. Yesterday it seemed like it was happening within 5-10 mins of power on. It feels like a hardware issue to me. Unfortunately I bought my unit second hand, and it is not in warranty :-(

Hi Dick,

Just to let you know, yesterday Richer Sounds picked my unit up for repair as I had done everything I could do to try and fix the issue at home. I will let you know what the outcome is.

Thanks Danny - and good luck !

A good friend of mine suggested it might be a overheating problem. Interestingly, I did reconfigure my AV stack not long ago, and in doing so I reduced the clearance above the receiver from 2-3 inches to less than an inch. It has run like that quite OK for some time, but then again it is the coolest room in the house, not usually open to the outside air - until the recent hot spell, which is when the problem started . . .

I'm not completely convinced, but I have adjusted the stack to restore the 2-3 inches clearance above the receiver. And so far it has been behaving itself. We will see !

Thank you.

I considered overheating, but I don't think it's the issue in my case. I have reasonable good ventilation around my receiver. It was picked up yesterday, but before that, it was behaving it's self in the brutal heat we had earlier in the week, a lot more than it has been over the last couple of weeks! Also, I always seem to get the issues at the time I turn the receiver on or shortly after, so it hasn't really had time to heat up.

Additionally, when my receiver goes into protection mode, the power light is flashing red every 0.5 seconds. See the extract from the manual for my receiver below. If it was overheating causing protection mode, I would have expected the power light to flash red every 2 seconds.

Power turns off and the power indicator flashes in red approx. every 2 seconds.​

The protection circuit has been activated due to a rise in temperature within this unit. Turn the power off, wait about an hour until this unit cools down sufficiently, and then turn the power on again. link
Please re-install this unit in a place having good ventilation.

Power turns off and the power indicator flashes in red approx. every 0.5 seconds.​

Check the speaker connections. The protection circuit may have been activated because speaker cable core wires came in contact with each other or a core wire was disconnected from the connector and came in contact with the rear panel of this unit. After unplugging the power cord, take corrective action such as firmly re-twisting the core wire or taking care of the connector, and then reconnect the wire. link
Turn down the volume and turn on the power again. link
This unit’s amplifier circuit has failed. Unplug the power cord and contact our customer service center.

Yes, my receiver exhibited exactly the same behaviour, which is why I too am somewhat sceptical about the problem being overheating. The mystery being why it doesn't occur more frequently, which I would expect if it were something like a bad speaker connection.

Interesting also that you say the problem occurred shortly after power on. Also exactly what I was seeing when it was really bad, One evening it failed 5-6 times, each time within 5 mins of power on, once with no connected input devices powered on.

I suspect I'm not out of the woods yet !

Denon recommended clearance’s are 5” above and 2” on both sides.

Just a quick update; my receiver has been with Richer Sounds for 3 weeks now. The only update I have had is that it is with the 'Denon Agent' and that they are hoping to have a further update for me this week.

I have to say, I am a little disappointed it is taking this long to sort out. TV speakers really are rubbish in comparison! :(

Thanks for the update Danny. Very frustrating. I guess they may be trying to recreate the problem without success.

I haven't seen the problem since I gave my X3300 more air space above. But I'm not confident it's actually gone.
