I do get .5 sec red flashing, the heat sinks (2) get warm, but not hot. Could this be the power supply or the audio IC?
Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

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're drawing too much power from it. Sounds like maybe your sub is hooked up wrong, double check that.

If the RCA TV has HDMI input connect as follows:
1. Connect an HDMI cable from the Directv box to an HDMI input on the Denon.
2. Connect an HDMI cable from the HDMI out-put on the Denon to the RCA TV
3. Select input the DirecTV is connected to at the Denon, at TV select HDMI input Denon is connected to TV.
4. On front of denon press the input mode button to select auto
If the RCA TV has Component input (Green,Red,Blue) connect as follows:
5. Connect Component Video and Audio cables from the Directv box to a Component Video and Audio input on the Denon (TV, DBS,VCR).
6. Connect a Component Video cable from the Denon to the RCA TV Component Video input.
7. Select input the DirecTV is connected to at the Denon, at TV select component input Denon is connected to TV.
8. On front of denon press the input mode button to select aut
If the RCA TV has Composite input (Yellow) connect as follows:
9. Connect Composite Video and Audio cables from the Directv box to a Composite Video and Audio input on the Denon (TV, DBS,VCR).
10. Connect a Composite Video cable from the Denon to the RCA TV Compositet Video input.
11. Select input the DirecTV is connected to at the Denon, at TV select composite input Denon is connected to TV.
On front of denon press the input mode button to select auto

Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.
SOURCE: 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.
