Just checking...you are plugging into the right voltage (110 or 220V), right?

OK, it could be a short in the speaker wires. Try disconnecting the speaker wires at the back of the unit and try again.

Most likely: Others have found a defective 15V voltage regulator. If you know what you're doing, you can check these and other power supply components (rectifiers and filter capacitors, for example).

Another possibility is a short in the amplifier section.

I have an AVR 335 less than 3 years old no sound


Hello

Yes, there is something you can try, to know where to look for the problem if this happens again. If the receiver is still under warranty, just send it back, otherwise, open up the amp and trace the path back from the speaker channel to the capacitors on each channel, this is usually the problem(you should be able to see if it is blown, cheap to repair).

If all the channels went out at the same time, there is something wrong with the central unit, to repair that, if it is not the above problem, cost expensive.

Hope this can help you.

Kind regards
Andrea

Denon AVR-1604 too large front speakers blew the avr


Try disconnecting the speakers at the receiver. turn it on radio or any other source and turn up the volume. If the receiver still shuts of, there is an internal capacitor issue and needs serviced. More than likely though, it's a speaker problem. If the speakers were underpowered and at max volume, chances are the damage was to a voice coil in one of the speakers. If the receiver continues to stay on without being connected it's ok. check your speaker wires as well. Frequently loose braids on wires touch each other and create very little resistance until turned up, more volume, more resistance. Then the receiver puts itself into protection mode so no damage will occur. If you need further help, post a comment and I can help you troubleshoot further.

Denon AVR -1604 Powers off after 3 seconds


Check in the amp section for a short on the output transistors. It may need a resistor or two also. I doubt that it would be in the power supply.

B Speakers: Rear A Speakers and Sub stay on


First, check you wiring. Have you tried to turn off all speakers then turn on only the "B" set?

Might also be your "surround" settings. Try a "2" channel mode if available.
