Question about Denon AVR-1804 Receiver

1 Answer

No display; No power

I tried turning on the Denon AVR 1804 one day and I had no display and no power. I performed the microprocessor reset procedure with no luck. Then, I opened it up and found the fuse in the bottom was blown...so I replaced it, retried microprocessor reset and tried powering up again. Blew the fuse again. Any suggestions?

    Thanks Dan,
    I have a local "Denon certified" repair shop nearby. Would this be necessary? Or would any old shop do? It cost's 40 bucks for the certified shop to tell me what's wrong. If I chose for them to fix it, the 40 bucks goes to the repair.

Your unit has a hard short in it. This is usually a power supply problem. Most likely the rectifier has failed. This should be a relatively simple and inexpensive repair. Figure on $10 for parts plus the local labor rate.

    ANy shop should be able to repair this. I work on many brands without being a "certified" servicer. The certification becomes necessary when warranty work is required. Also, many shops that are authorized service centers must demonstrate ability and quality. I've been doing this too long to worry about certification. Check around. Reputation is worth more than certification.

Denon AVR 1804


You need to get the manual and do some reading first. I couldn't find the AVR-1804 but the AVR-1803 is avaiable. It should be close enough to get you through connection and setup.

How do I reset my Denon avr-589? I would like to reset my reciever back to original settings.


Press the power button, and speaker a and speaker b simultaneously and hold until the display begins to flash then release speaker A and speaker B buttons. That resets the microprocessor.

Denon avr-1804 its turns back after 5 sec


Disconnect all speaker wires on back and then turn on. If it happens again, it's most likely a power supply problem. If it doesn't happen again, it was probably crossed speaker wires.

My denon reciever display wont't work


I read something the other day in the user manual about re-setting the microprocessors if the display doesn't display properly. Turn the amp off.  Hold down the input mode & analog buttons while turning power on. The whole display should flash on & off at 1 sec intervals, then release the two buttons. This resets the microprocessors & supposedly fixes display problems.

My Denon AVR-887 Keeps turning itself off


I have one and the same thing happened. try resetting your microprocessor and if that does not work, then check the wiring of the speakers. if that is working fine and no wires are touching then I unplugged everything and was still having the issue. took it in for service and it was found that the transmitor was shorted as the speakers that I was using was too high in ohms. it is possible that it could be your caps also if resetting the microprocessor does not help. You can find out how to reset the microprocessor from your manual. If you have the Denon avr 887 with the system turned off hold the power on button and the speaker A and B at the same time for a few seconds. This is compatible to rebooting your computer. Hope this works for you as this was and is my husbands favorite past times.
