My 6 year old receiver had operated flawlessly, but last night while watching TV on my DirectTV satellite and my AVR-3806 receiver powers off and the red light starts blinking. Before powering down, the sound was not modulating properly. The voices were much lower than the background music and laugh track. I checked all of the wiring, and everything seemed to be in order. I changed the receiver input from TV to my Xbox, and everything works perfectly. Is this the satellite box causing the problem or receiver?

This is a very common problem with denon receivers of the 2001-2-3 vintage. On almost every one, there are 4 little "surge" resistors in the power supply. These werent quite robust enough from the factory and one day would just burn open for no reason. Well, actually there is a reason, the "surge" that happens every time you power the unit up eventually weakens the resistors and then they pop.
You need to take this to a denon service shop as I GUARANTEE they have seen this before. They need to check resistors in the picture, locarde above the **** rectangular connector. Resistors numbers R141, 142, 148, 149:
These resistors when measured, should be less than 10 ohms each. If they are more, then they are blown. If they are blown, then have the shop check the channels for blown output transistors. If the outputs are OK, then these resistors should be replaced with 1 ohm 1/2 watt metal -film flameproof resistors.
You might need to be prepared for a large bill, because the entire unit must come apart to replace the resistors, however, just checking them takes only about 10 minutes...
Good luck and don't try this at home.

It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.
When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.
If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.
If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.
On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".
If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.
I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.
If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.
If I can be of any further help, let me know.

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.
SOURCE: Voice volume is low compared to background music
Could be a number of things.
Most likely your surround sound mode. Some people dont like Dolby. Try to switch to 5 channel stereo.
Other option is to turn the center channel speaker channel volume up. Voices and dialog come from the center channel speaker in Dolby modes. Post back if you need instructions.
Please rate my solution.

I was able to get sound, but no video so far.
