Re: avr 3806 power shuts off when volume turned up

Hello david 420

It looks like your receiver's high-speed protection circuit is being activated. It is definitively not a fuse. When a fuse pops, you have to physically replace it. When the protection circuit is activated, the speaker output is cut off and the power supply indicator flashes. There are a few reasons why this happens:

1.- Your speaker wire connections are loose. Whether they are banana plugs or bare wire ends, make sure the speaker terminals on the back of your receiver are tight using clockwise turning.
2.- Verify that your speakers have an impedance between 6 and 16 ohms. Your receiver was designed to work with that impedance range. Any impedance lower than 6 ohms will activate the protection circuitry.
3.- The receiver is used at high volume levels over a long period, which results in an
extreme temperature rise. Improving the ventilation conditions around the unit might help alleviate the problem.

If after complying with these suggestions, problem is still present, you might need to have the unit checked by a professional for possible circuit failure.
Hope this helps. Let me know.

Reciever shuts off

Most likely cause of a receiver shutting off when turned up is a bad speaker or speaker wire.
As far as having to turn it up almost all the way, that is the norm on most new receivers today. Most receivers no longer have a true preamp section, which means you have to run the main amp much harder in order to get a decent sound level.

Just fixed this myself - made my head hurt to figure out. 1. Switch to a setting (say DVD). 2. Watch the AVR screen as it switches. You'll see the audio and video settings. For example, Audio = DVD, Video = DVD (Mine showed Audio = DVD, Video = DBS even though is was set correctly using the SETUP for audio and video)3. Under the round control knob on the left, push the (tiny) Video Select button. 4. Turn control know to choose the correct video source
Your system should work right. Mine did.

I was watching a movie on my denon avr-3808ci and all of a sudden it made a loud sound and it shut off. The power button was flashing red and wne I tried to turn it on, the power button would turn green...

probably one of your speakers has blown.. disconnect them all. turn the reciever on.
if this works turn it off connect one speaker and turn it on.. keep going until it goes red...
when you find the speaker discennect all the other speakers keep this one connected and confirm that it is this speaker giving issues.

if the amp doesn't come on with all speakers disconnected, remove the visual outs and start it with nothing connected. isolate the issue if this works. otherwise it might be your amp.

When reciever is turned on it shut's right back off. It will not stay on. Also it would loose volume. Why is this and can it be repaired?

this is a main power issue and the only way to fix it is to replace the main board which is the heart of the reciever . costly exercise . sorry to hear that

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.

Avr Shuts down at high volume

It does that because there is a safety feature in all the newer devices. If your system is turned up to high you would blow your audio outputs or speakers. That's why it shuts off.

Volume Control

I had the same issue, there is a Late night mode on the remote that minimizes the volume of a loud scene so you don't have the constantly adjust the volume. Works great if you are trying to watch a movie while others are trying to sleep.
