    I have the same problem, it overheated because my wife covered the vent holes. I had this problem once before when I first purchased the receiver and the fix was to reset the receiver. I had to call the location where I purchased to do this but now that location (tweeter center) has closed.

SOURCE: Powers turns on then off

See: http://www.denon.ca/hapdfs/avr2105mane.pdf, page 72. In my case, the problem was a connector between my receiver and television. I unplugged it from my receiver and it now works.

SOURCE: Denon AVR-1601

This is a very common problem with denon receivers of the 2001-2-3 vintage. On almost every one, there are 4 little "surge" resistors in the power supply. These werent quite robust enough from the factory and one day would just burn open for no reason. Well, actually there is a reason, the "surge" that happens every time you power the unit up eventually weakens the resistors and then they pop. You need to take this to a denon service shop as I GUARANTEE they have seen this before. They need to check resistors in the picture, locarde above the **** rectangular connector. Resistors numbers R141, 142, 148, 149: 75f69d7.jpg These resistors when measured, should be less than 10 ohms each. If they are more, then they are blown. If they are blown, then have the shop check the channels for blown output transistors. If the outputs are OK, then these resistors should be replaced with 1 ohm 1/2 watt metal -film flameproof resistors. You might need to be prepared for a large bill, because the entire unit must come apart to replace the resistors, however, just checking them takes only about 10 minutes... Good luck and don't try this at home. Rob

SOURCE: Denon avr-1804 its turns back after 5 sec

Disconnect all speaker wires on back and then turn on. If it happens again, it's most likely a power supply problem. If it doesn't happen again, it was probably crossed speaker wires.

AVR-1508 7.1 Channels Receiver: My Denon AVR-1508 won't stay on. Once I try to tak...


Not familiar with this model but seems like the protection circuit is kicking in, this could be caused by an imbalance of Ohms between channels or a short. remove & check all speakers and cables for continuity or shorts, does the unit power on without speakers or in a different mode (surround off).
always add speakers in pairs (L&R) before testing to prevent possible protection circuit, test main speaker pair first then add surrounds (all according to the allowable Ohms range for the amp of course)

After playing my AVR-2802 Denon a while approx 3-4 hrs the sound output juts turns off, after letting it cool down a while it will resume playing ok , then repeats the cycle of loss of audio output.


Seems to be a heat related issue, when it " cools down " awhile it resumes audio output? Be sure you are allowing air circulation around the receiver, I am note sure but I do not think Denons have inboard fans, you could try a ciculating air fan on the unit after playing it for a couple of hours if the receiver feels hot.

Denon avr-1404


Hello,
I got the same problem and on my AVR1404 it is the regulator
-15v (7915). You can control voltage on
R145 : +15v and
R146 : -15v.
The other side of these two resistances are joined together.
Good repair....
