Okay, I admit, we do have a lot hooked up to our system; but we do our best to keep the receiver well-ventilated.
It started every once in a while...just shutting off....especially when I'd turn the volume up.
Now, It shuts off almost immediately, even with the vol. all the way down!
HELP PLEASE! I can't afford a new system!

Re: Keeps shutting off
Are you able to check whether any of your speakers may have been blown? or have a direct short to ground ..this usually indicated by the amplifier protecting itself and shutting down,, try un plugging one speaker at a time and you may find that it is one of the speakers ....then get a replacement or get it repaired

My first thought would be that when you moved the receiver to connect another DVD, the problem quit since the speaker wires moved. The best way to test would be to re connect the original unit the same way as the new unit and test again. If it still cuts out, disconnect the speaker wires and re test. if it still cuts out, try the new player and test again. if it does not cut out, there may be a problem with the old units audio output. Generally if its a problem with the receiver it would not matter what source you are using, even the tuner on the receiver, if there was a short in the receiver it would cut out. Let me know what your results are and I will help more if needed. Best of luck!
If your reciever is in a tight enclosed space, than it will overheat and shut down to protect itself. Try to get some ventilation to it by either opening the cabinet door, adding a fan, or pulling it completely out of the enclosed space.
the best thing to do is turn off the speaker outputs, if you have the capability on the front panel, turn off the unit, disconnect all speakers. after that, turn it back on and see if it works ok. turn the speaker switch back on, do all the clicks from the relays sound normal? is it on now? if so, you have a bad speaker. connect them 1 at a time til you find the bad one. if not, then the unit is bad and needs repair. it would likely have been caused by a defective speaker or internal component of the speaker, or the speaker wiring. good luck
Aside from any intrinsic problem with your receiver, the usual suspects are;
1) Poor receiver ventilation.
2) Very high levels of bass.
3) Shorts in the speaker wiring.
4) A rubbing loudspeaker voice coil.
Try unplugging the entire unit and letting it sit for 5 minutes. See if this helps. If not, you need to do a complete reboot, which will cause you to lose your settings, but will probably solve your problem. To do a complete reboot, you will need to hold down two of the front bottons on the front panel. I'm not sure which, so either consult your manual or see other posts here which describe the reboot process for Denons. Hope this helps.
you may be using an equalizer? try to pop-up the volume with all tone controls in flat mode. see if it still cuts off. if this is the first time youencounter this then something must be wroing with either your speakers or your amp. unless your ventilation is not good enoughg, you can also try placing a blower on top of your unit to cool it down
I have the same receiver and the way to fix is simple. in the main board of this unit there are 5 connectors and they slide into other components like Lego. the issue is the king of material they are made of it's cheap. if you reseat the mainboard it will fix it for a day or two, them it will start again. the easyway is to re seat the board and put a fan inside of the receiver between the transformer and the inside of the amp pointing down about 20 degrees connect the fan to a ajustible voltage adapter and connect it to the outlet in the back of the unit. so it comes on when you turn it on. this voltage adapter is cheap. the adapters people buy for phones and or MP3's at Radio shack or Best buy it goes from 1.5v to 12 volts/ this way you can control how loud the fan is in side the receiver. i find 4.5V does the trick. The connectors on this board start to loose contact with some of the pins when heated. the fan keeps it cool enouth to fix the issue. I fixed manny these ONKYO 804's this will fix it. you just have to do it. the main board is inder the HDMI board in a Vertical position running from one side to almost the Power supply. it has 2 screws also holding it in the inside middle back of the amp. Becarefull with these amps 75 V at 23amp's DC is no joje leave it off for a couple of hours to satart working on it. Good luck.
