I was futzing around behind my Denon 3310CI when it was powered up last night and suddenly all the audio stopped. When I power it on, I hear a huge pop from the speakers immediately then it goes through the normal relay clicking and startup. All indication is that the receiver is fine, video is passed correctly, headphones work.

Other symptoms:
- the front panel only has FL and FR enabled, no matter what I set in speaker setup.
- in setup, the option for Channel Level has been removed from the menu (it was there prior to my futzing, because I was using it!)

Both of these say to me that it thinks it's locked in headphone mode. Others have suggested blowing in the headphone jack, which I've done, but I think it's a stuck relay. I have reset the firmware, but that didn't fix anything (just wiped all my settings).

Is there anything I can do other than take it in? Can I fix the stuck relay myself? Please help!

Did you use a can of compressed air or insert/remove a headphone plug a few times? Try resetting the microprocessor a few more times. Also as you're out of warranty you may want to consider replacing it with the newer successor model, X4000 which uses the much more advanced Audyssey MultEQ XT32 vice only MultEQ found only on the current lower level models.

Yeah, I'm looking at the Marantz 8801 to replace it, but $3500 for a $20 fuse/relay seems like such a waste.

I reset the microprocessor a few times, it's probably the relay. I didn't try compressed air (I did blow really hard), but i'm sure it's not dust in the headphone jack. It happened because of my own stupidity behind the panel while it was on.

If someone has a photo of what the relay/fuse looks like, I can probably figure out what to do, but I don't know what's what under the hood.
