Question about Denon AVR-987 Receiver

1 Answer

My Denon Receiver AVR-987 keeps turning itself off. I'm not sure what is happening. It has been hooked up the same for months now. I'm not sure if their is a surge causing it, the Sony TV is causing it or the Denon is messed up.

    It is rather hot. I moved it from where it was sitting and thought about running a fan on it. I'm having the apt complex check for power surges also. The unit is only a year and half old.

    The unit is and has always been plugged into a Power Surger. I had it plugged into a very expensive one that worked fine in my home, but when I moved to the Apt., it kept reading high and shutting off. I thought it was the unit and moved the Denon to another Monster Power Surge Protector. It seemed like it was working fine, but recently started shutting itself off. I have eliminated the TV and Cable as being the problem. I thought maybe it was a bad HDMI cord. They are all Monster and so I moved the most expensive one to the Denon, but that didn't make a difference. I now have the unit out of the Entertainment Center and a fan blowing on it. I'm thinking I have two problems. Power Surging in the Apt (I've reported to the Manager and they are going to look into it on Monday) and the unit is overheating where it was sitting (nothing on top of it, but may not be getting proper ventilation). I'll see how the fan works out. I left it unplugged for a couple of hours. How do you "reboot" the 987? I have no idea what I did with the manuals. In a box..??

That is a common problem for many receivers. Over heating, amplifier overload etc. Are you playing material through it at a very loud volume for an extended period, particularly with a lot of bass? If so try turning it down and/or defeating any equalization or turning the bass control back to zero. If you moved the unit make sure it is getting enough air flow and that there is no other heat sources near it or anything sitting on top of it.

    If you plug it into a surge protection unit like an inexpensive but effective, Tripplite Isobar it will offer protection from surging and extend it's life as well as block some interference. But the likelyhood that power surging is what's causing it to shut off is unlikely. When surging does happen it's usually during electrical storms or sun bursts and happens on a large scale, not just to a single isolated electrical appliance. There are other causes as well but it's just as rare.

    The problem I had with the unit was caused by lack of proper ventilation. Once I moved the unit to a sepate stand with lots of ventilation, the problem went away. It is and was hooked to a surge protector. I had been blaming it on the apartment I was living in, but it was most definitely a user error. :)

There's no user parameter for "no sound during Test Tones" so a reset would be futile.

Carefully examine the front panel for clues like a misplaced Mute, Tape control or Multichannel Analog (EXT) Input selected.

Are your DD TV and DBS referring to the same source device or are they separate, say, cable Box and Sat Box?

Start over with the digital audio assignments for wherever you plugged in the digital audio cable from (guessing) your Cable TV box (recommended as "TV" is not usually a great source for audio).

You might also want to define the specific cabling of things if more is required. Exact point-to-point paths and cable styles for audio and video.

Our denon receiver keeps going off-


replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

My Denon AVR 3806 keeps turning itself off, why?


Your receiver has short circuit somewhere. The protection circuit shut off the unit to prevent more damage. You can try to disconnect all speakers. If there is not improvement, you need to send your receiver to repair.

Connect all of your cables to your display and then connect another set of cables to your audio variable out from the television to the input you wish to get sound from on the receiver. Then make sure your tv is selected to the input you plugged the wii into, for example, Front video or Video 1 etc etc.

Avr-2802 constantly restarting itself and flickering on and off


check all speaker wires from the receiver end and the speaker ends. Just the smallest strand of copper could be touching something it should not be touching. Make sure all copper is in the speaker post and not hanging out. The receiver is getting a short and shutting off to protect it self. This could have happened since you were just plugging things in.
