    I have the same problem, It turned off all of a sudden when I pulled a wire out from under one of the footings and it seemed to take some kind of jolt when it fell, The fall was no more than the thickness of the power cord, and shut off immediately. Ever since, it turns on and then in a about a 3-5 seconds it turns off. No sound is ever heard at any time.

Your receiver is going into protection mode.
Need to know what type of reciever. In the self diagnostic mode there are code that will tell you why it is cutting off. If it is as you say you, as for the fall, you may just be able to reset it in diagnostic mode and everything will be fine. You can search for the service manual online. It will explain the diagnostics and the protection mode in detail.

Protect appears when the receiver is cut on. what does that mean?


Hi,
I just wrote the reply below for someone who is having the same problem with their receiver than you are. So here it is. Enjoy. I hope it is a help to you.
Here is some theory as to why this is happening to your receiver. The "protect" mode is designed to respond to several related conditions:
The first reason is a wiring fault between the receiver and the speakers such as a strand of speaker wiring touching the opposite conductor so that there is a short circuit. If this happens the receiver will overheat and then shut down to protect itself. This is a good thing. otherwise you simply have a very expensive repair on your hands.
The second reason happens when the receiver is inside a closed cabinet and overheats because not enough air is going through it to keep it cool. So it shuts down in this circumstance.
The third reason happens when the receiver is playing loudly beyond the limit of it's design. In this case, it will overheat and thus shut down to protect itself.
Here is a diagnostic procedure for the first reason above:
What we are doing, in this case is looking for a shorted out speaker system, or wiring to speakers, or cables or components that are connected to the receiver that have a short circuit. This is what I would do if I were called to your house to debug your sound system.
1 Disconnect one set of speakers at the back of the receiver and turn the power button on again. See if it stays on.
2 If not, remove the next speaker and keep repeating the test.
3 If it still stays off, disconnect all of the equipment connected to the unit, one piece at at time.
Somewhere along the line, the receiver may not shut down. If that is the case
identify the the offending cable(or component)and replace or service it.

To correct the second reason simply leave the cabinet door open while the system is playing. The only problem with this solution is that if you don't have cabinet, it makes no sense.

To correct the third reason. Watch the volume level while using the system.

I hope this helps you.
If you have any questions at all, please contract me through this website.
Best Regards,

When i power on the device, it comes on but goes off about 5 seconds later.


Hi...

1st thing to check is for GOOD speaker connections at both ends
and not mixing A and B speaker wiring.

A Denon is usually a good brand. Might be worth servicing if need be.

Wont stay on.


The only way you can fix this is you have the proper tools and have very good soldering skills. If so, I will post more instructions on how to fix this.

It has a blown channel, it can not be fixed without some good troubleshooting skills. The protect mode is so you don't cause more damage to it. If you continue to turn it on, you may cause more damage.

Your best bet is to take it in to get repaired at a service center.

Let me know if you require more help,

Power comes on for only about 4.5 seconds, then shuts off.


1-speakers terminals are short circuit----turn it off and correct speakers terminals.
2-blocking of ventilation holes of the set -------turn it off and let it cool down and make a good ventilation around ventilation holes.
3-the unit is operated at continuous high power condition------turn it off and let it to cool down and then turn it on.
