Works fine until this morning. When power up the power blinks from green to red ant won't power up.
There was a power surge over night, End mess it up,That will cause it to do that.You are better off just to go out end buy a different one, The repair is verry expensive,If it can be repaired.

I have repaired many of these Denon receivers over the last few years.
Since the headphones work, that means if you dis-connect the speakers it will turn on and not go into protect (when power cuts off a few seconds after turning the unit on).
The most likely problem is a bad speaker. to find out which speaker is causing the problem, do this.
Start out with just one speaker connected and then turn on the unit. If it turns on and plays music, you know that speaker is good.
Now turn the unit off again and add another speaker and keep the first speaker connected. Once again, if the unit plays, that speaker is also good.
Keep doing this same procedure one speaker at a time. As soon as you connect a speaker and then try to turn on the unit and it goes into protect, the speaker you just connected is bad.
To confirm that this speaker is the bad speaker, dis-connect all speakers and only plug the suspected bad speaker into a speaker jack that worked with one of the other speakers.
If the unit still goes into protect you know then that you have found the bad speaker.
If the unit still goes into protect, that speaker is bad and you will need to take it in for repair or replace it.
make sure you use 8 ohm speakers. if i remember correctly these Denons can use 6 ohm speakers, but those are harder to find and most home speakers are 8 ohms.
If the unit does not go into protect and that suspected bad speaker plays in one of the other speaker jacks, what you really have is a bad channel in the amplifier, the channel that the suspected bad speaker was previously connected to.
If you find out you have a bad channel, you will need to take it in to an repair center. Preferably an authorized Denon service center. There are not very many of those around. I work at the only authorized Denon service center in the entire state of Michigan.
If I can be of more assistance, don't hesitate to ask. And a good rating is always appreciated. :)

speaker terminal are short circuit,switch power off connect speaker properly then switch power back.
-the ventilation holes of the set are blocked-turn power off and make good ventilation around leave the set to cool and turn power back.
-the unit is operating at continuous high power turn it of and allow for cool down and switch it back.

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.

I have the AVR588 7.1 Surround A few models down from the on mentioned here. Same problem, turn it on then after warm up of a minute or so it shuts down and the standby red light flashes. It has the same part failure. KIA7915PI. Ive ordered 4 so I have backups since this seams to be a high failure part. I tried crossing the part to a higher quality part like NTE but I cant find one. My searches on the net I did find many have the same problem but noting on resolving it. The way I found the problem is I associated it as a termal issue so I got a can of freeze it at an electronic supply store and cooled several components one at a time cooling it to see if I could keep the unit on longer. Low and behold as long as I kept the KIA7915PI froze it would stay on. Im still waiting for the parts but to get by I have removed the transistor and soldered three long wires to the pc board in place where the transistor was and the part soldered to the other end. This is to extend the part out so that I can keep it cool in a glass of Ice. I dont recommend anyone doing this if your not familiar with electronics. I was careful soldering the leads of the transistor to the wires not to cross them and make sure not to emerge the leads of the transistor into the water as the ice melts. Crazy but it works for now. As I wait for the part i can kick back and watch some movies with some rum on the rocks as my receiver enjoys its 15v regulator too "on the rocks". LOL
