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 had this same experience and after hours of attepts to fix it (including the suggestions on this site) I found that the company that installed and set up my system literally disabled the "set up" on the remote so that it could not be changed. To fix this (and/or confirm that this may be your problem) reference page 39, "all reset functions" to reset your remote back to factory settings. As soon as I did this and hit "set-up" -- the set up menu popped up and worked appropriately. Hope this works for you!

SOURCE: connection problem with HDMI cables on Denon AVR-589

Hi dmsgolfer22,

If your Time Warner Cable box is old enough that it has a DVI output it may have HDCP (copy protection issues) with the receiver. If you are having to use a DVI to HDMI adapter to connect to your receiver (output from Cable Box to input on Receiver) then it's very likely your cable box may have may not output the signal because it detects the HDMI repeater in the receiver.

The two best options to correct this are:
1. Connect the DVI to HDMI cable directly to the input on the TV, you lose the convenience of the video switching in the TV, but it will solve the problem. Then connect the digital audio output from your cable box to the receiver, although you've probably already done this.

2. Contact your cable provider and check into the possibility of them swapping out your cable box for a newer model that would have an HDMI output. This would be the best option since the HDMI output on the cable box would give you both the Digital Audio and Video through a single HDMI cable.

Let me know how it works out for your, or if you have any questions.

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.
