im having a denon 2200 suddenly it swiched off with blinking
red light i turned it on then it worked normally
so then i changed the eco mode to off and change
ohms to 4ohms just in case
then i watched movie for 2.5hrs it was working normal
do i have to be worried? is my receiver starting to fail?
any precautious actions to be taken?
im already left with dead onkyo 646

I have never had a Denon before, so I'm not much of help here. It's getting hot, by any chance? Has enough room to "breath"(ventilation room)?
On my older Onkyos, I have used a laptop cooler, with an adjustable fan, to cool the receiver. I have adjusted the RPM, to a level, that it wasn't bothering me, but it was still decent cooling, for the receiver. I have plugged it in into the TV's USB port.
If it would be mine, I would take off the cover and I would re-tighten the final transistors on the heatsink. At least on the Onkyos, I have always found them, a bit to loose for my liking.

its a airconditioned room and its in open
the breathing room s plenty
im also planning to use laptop cooler should i blow the air inside the receiver or out of avr?
i dont understand re-tighten the final transistors on the heatsink?

The fan should suck out(pull out) the hot air. The final transistors are mounted to a big aluminum heatsink, and those screws get a bit loose.  Most likely, they will be at the bottom. I use one of these, to tighten those screws: www.harborfreight.com/8-piece-right-angle-screwdriver-92630.htmlIt could be something else, this is just an idea. |

What do you hear at 60-70 db?
The receiver gets hot as you use it?

Maybe you went overboard a bit.
Probably one big slow fan(140mm-200mm), would be better.
