Question about Denon AVR-883 Receiver

1 Answer

Denon AVR 883 no sound from any source including zone 2 speakers

I have had a Denon AVR 883 for about 8 years, all of a sudden I intermittently get no sound from any source. Sometimes turning it off then back on brings it back.. Sometimes it will come back on by itself while the unit is on. power on cycle seems to be normal i am getting the power relay click and the speaker circuit click. Any one have any suggestions.

This sounds like a thermal issue, meaning after the receiver has been on for a while it gets to warm and then fails. I suspect after 8 years the unit may have accumulated some dust that is not allowing the heat sinks to dissipate heat adequately. I would use compressed air and blow the unit out. Some computer stores have blow stuff in a can that work well. If you have and air compressor, dial it back to 10 psi or so. You will be amazed at how much dust will come out of that unit so you may want to unhook the unit and take it outside. Also be careful not to stack anything on top of your receiver. Make sure there are lots of openings around the unit. High temperatures kill electronics.
Hope this helps.

TV's are not your best source of audio. Get the TV-related audio digitally from the source, NOT the TV.

No sound when on internet radio, playtime is running, volume is not muted, internet ok


It was solved by turning the receiver off with the power button (not stand-by). After turning on the netradio did have its sound back. Apparantly it must be running some sort of Windows os.

Sound cuts out


This sounds to me as an issue not with your AVR but with your cable unit. I have seen this where there is a sample rate issue with the cable boxes. I would try to get another cable box, and see if the issue persists.

Denon AVR 1705-no audio on TV


I have had the same problem and was told that it is a "board" inside. Essentially it has lost the surround sound ability and can only play things in Direct/Stereo. Mine is just over 2 years and I originally thought my kids had hit a button on the thing causing the issue...ended up paying $100 to trouble shoot it and confirm that it is internal and more expensive to fix than replace. Can't say that I will be buying a Denon again.

Denon AVR 883 Audio glitch


More than likely the protector circuit is getting activated... You can't go below 6 ohms on the surround back which means you need 12 ohm or higher speakers for outside (since the two outputs for surround back/zone2 are in parallel). As a simple diagnostic test, disconnect one speaker and see if the sound survives longer than 2 seconds.

Denon AVR-1803 shuts down


I am a Tech in Michigan and have worked on lots and Lots of Denon AV Receivers. These units have Protection circuits for Overcurrent, Dc Protect, 15v Regulator inbalance, Rail Voltage Inbalance, Low Ac Voltage, Low Standby Voltage and Thermal Protection just to name the ones I remember. My guess is you Probably have either Poor Intermittent solder connections or Amp is not Ventillating Properly. Make sure you leave room above Receiver to Vent and You are using no Less then 6 ohm speaker Impedance per ch. Refer to Speaker Impedance chart on back panel . [email protected]

Intermittent audio output


It's quite possible one of the relays is failing that is part of the switch between audio output choices.  Do you notice any output difference between a certain output (i.e. dvd, tape etc)or is that point arbitrary?
