    my denon AVR 1905 also when powering on says AV surround reciever then powers down with the power button flashing red.Ive checked all terminals,none are touching and i,ve even unplugged everything and its still the same.I,ve used this amp practically every day for 3years or so with no probs.The only thing i do differently over the last few months is switch it off from standby on the main plug

    I also have a denon AVR-1905 with the same problem. All the lights come on it clicks two times then it shuts down. I have tried everything I even took it to local shop and they said the power board would have to be replaced but said it would cost more for the board then for a new receiver. Before leaving the tech wispered that they really didn't know what was wrong thats just the answer they give when they have no answer.

My friend kept turning it up and i kept turning it back down then it just said poweroff


Sounds like your "friend" has cooked something. It could be one of your speakers (do they all sound ok for the 5 seconds it runs?), or it could be the receiver....
I would try disconnecting all the speakers and see if it stays on. If so, it may be one of the speakers. Connect them one at a time, and see if you can tell.

How do i keep the power on when it goes out in five seconds?


You can't. It's the systems' internal safety circuit shutting it down friend

Not an expert on those machines but it sounds like the power output stage is faulty and overheating causing a shutdown.
Needs new output stage or repair ?

Why does my pioneer stereo say POWEROFF and not turn on


Most likely it is going into a safe mode as one of the speaker connections might be creating a short in the audio amplifier. Check speaker terminals connections. The model number of the unit would be helpful to know.

Yamaha RX-V690 powers up and turns right off??????


Hi...
All the speakers are connected at both ends?
If so, you have a power amp electrical break.
Not an easy fix.

POWER OFF/ SHUTDOWN


I found the solution for me! I had the problem where after 1-5 seconds, my receiver would simply shut down. Twice now I've solved it.

The problem is most likely that you have speaker wire that is touching the opposite terminal or coming close to doing so. Check all your speaker wire terminals and make sure that they are not touching at all or coming close.

Also, make sure that your speaker wires are truly in speakers. If you have speakers plugged into the back of your receiver and then sitting out on the other end, that could be the problem as well.

I hope that helps - it solved it for me!
