I got a Denon AVR-1909 and it is turning off with a 0.5 seconds flashing red ring after playing 20 minutes of Music or watching a movie. So far i tried to disconnect all speakers, and the same thing happens. i did the same thing with opened cover, it runs for hours. I Positioned a fan to the hottest part of it (power supply) and closed the cover again, but it also turns off at about 20 minutes. How can i find the defective part?
Well on most models red ring singals :
1 ) speaker wires touching something they should not
2 ) internal overheating, shutting down to protect
3 ) something is wrong, bring in for service.
I'm guessing it's out of warranty?
Testimonial: "This is happening also without any speaker connected to it, so the first thing is probably reasoning, but not my problem. Internal overheating is very probable, but how can i check which part is overheating? i tried to measure, the hottest things are the contant voltage IC's of the epower supply, could the power supply be the problem? What does it cost to fix such a problem?"

We had the same problem, we unplugged and re-plugged in the Bose unit and the sound problem stopped!

Usually problems that start "out of the blue" after being powered-up for hours, caused by heat building up are due to things inside getting hotter and hotter until they fail. Unless something actually burns up, this is a reversible problem. Shut it down to allow it to cool off, and it works again. I own a SA-HT700. After 24 hours or so of being powered-on. it starts making a loud rumbling noise. Turning it off for 20 minutes fixes the problem. There's a fan on the back of the unit. It does not work. The heat sinks inside my unit are not covered with dust - suggesting the fan has never worked. I rigged an external DC supply to the 12V fan, so now the fan runs all the time. I am waiting to see if this fixes the problem.

The issue might be that you have to send the LHT854 Back to the manufacturers and have the playback feature replaced. The playback feature is controlled by a device that is internal and very important to the overall function of the unit.
