Question about Denon AVR-2803 Receiver
After working great for 3 years when I tried to turn on Zone 2 (lately) the whole AVR unit shut off. I reinitialized the microprocessor (per the manual) and now I can select Zone 2 with the unit remaining on. However, I still can't get any sound from any of my Zone 2 speakers (Zone 2 volume is up enough) from any source. Thanks.

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.

You have to switch your remote into Zone 2 Mode. It will be an option on your remote. Once you put it in that mode, you can change the source just as you would Zone one.

SOURCE: i reset the microprocessor that
One or the output channels is probably bad you can check for a short on the output transistors using an ohm meter. Make sure that the receiver is un-pluged. The ouput transistors will be on a large heat sink.

Check your speaker wires on zone 2 and look inthe manual for speaker configurations with zone 2. you may have a speaker conflict. If you still have an issue, post a comment with your speaker setup and I'll help some more. Hope this helps
