How good are you with electronic repairs...? Do it if only you are confident...

The way you describe you problem it seems more like poor solder connections somewhere on the board. Usually these are at the voltage regulators where there can be some heat. Also, look for any connections that appear to be grasiny or have rings and resolder them too.

Alternatively, suggest that you take it to the Denon service center closest to you.

Best of Luck..

SOURCE: shuts off then red light indicator flashes, disconnected all speakers but still wont work

Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.

The receiver has an internal problem like bad power supply or burnt channel. You need to bring it to a local repair shop or mail it here.

Similar situation as previously described with the Denon AVR-1508, but mine will shut off after about 10-12 minutes the first time around and then ~2 minutes after it is turned off and then back on. Unit...


Most new receivers have a fan on the back, if you have one check to make sure it is working, most won't activate until the unit gets warm, other issues are bad solder connections on the audio outputs causing intermittent shutdown, as a final inspection check speaker connections to the receiver and speakers.

Denon AVR881 Turns on for few seconds then shuts OFF


(Probably too late to help you, but I'll post so others can see)
I had the same thing happen to my trust AVR-881 two weeks ago. Even re-initializing the processor was no help.
I took it to the repair shop. They replaced three transistors on the board, and charged about $175 for the job.

Shuts off after only a couple of sec.


Your reviever is "clipping". You need electronics service from a professional repair shop.

If you are savy in the world of electronics... Most likely you have a bad cap or preamp circuits that are overdriving the amp supply.

Denon AVR-4802R automatically shuts off in multi-zone mode


i had the volume of the multi-zone tuned too high and was attenuating it in an external control box. Once i took the multi-zone volume down to -25db, the problem went way. My main zone was operating around -35db so did not have the problem.

Denon AVR-3802 Problem


Check that your speaker cables are not touching each other at the amp end and also at the speakers as this will cause the amp to shut down.

hope this helps.

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 . kstahl65@att.net
