AVR3803 reverting to 'standby' and will not play

My receiver is about 2 years old and has been used very little. I set it up at my new residence and was playing it rather loud (but not nearly as loud as I had in other demonstrations). The unit tripped what the manual describes as a "protector circuit", and now it will not play at all regardless of settings. When turned on, all the lights come on briefly, then the lights go off without making power. The manual says if I do everything it suggests (which I have) and nothing works, then send it to a Denon service center. Does anyone know how to reset or otherwise defeat this? There is no service center for 300 miles. HELP!!!

Re: AVR3803 reverting to 'standby' and will not play

A componet sounds like it has blown out or shorted in the output circuit. There are no user replaceable parts im sorry to say unless you know how to trouble shoot and repair solid state circuits. A protection circuit is there so you dont burn up the speakers, as if the speakers did not have a relay to take them out of the circuits, a shorted output device would fry the speakers.

My Denon AVR-75 seems to stay in standby (red standby light is on) and I don'd get surround sound through it. How do I get it out of standby?

if the receiver does not power on from standby there is a problem like bad power supply or even bad macroprocessor. You need to bring it to a service center for diagnosing. 10-years old receiver, maybe better to buy new one.

My reciever plays then cuts out

They don't overload from missing speakers. I'm curious, what buggered the one speaker?

Examine all of your speaker wires carefully to be sure no unintended contact is made between them and anything else.

Is "overload" being displayed?

“OVERLOAD” starts flashing on the display.

Speakers are overloaded because of high volume.

1. Press STANDBY/ON on the front panel to turn off the receiver.
2. Stop the playback source.
3. Turn on the receiver again, and adjust the volume.
Speakers are overloaded because of short circuit of speaker terminals.

Press STANDBY/ON on the front panel, then check the speaker wiring.

If “OVERLOAD” does not disappear after turning on the receiver again, unplug the AC power cord, then plug it back in again.
If speaker wiring is not short-circuited, contact your dealer.

Sherwood RX-4105 Receiver will not stay on

Sorry to be the bearer of bad news but your unit has either a bad power supply or bad transistors and need serviced. Under 200 for the repair however, I'm not sure what the unit sells for new but weight the costs vs replacement. Hope this helps

The receiver goes on standby mode when volume is high

Your receiver is basically going into protect mode.

The SR 605 contains a microcomputer for signal processing and control functions. In an unlikely event, it may cause it to lock up. Unplug the power cord from the wall outlet, wait for 10 to15 seconds and then plug it back again.

Please also check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Take out all the wire and put them back again if necessary..
Some times even a little tiny frayed wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit.
Just check your speaker as well....whether they play all right thru another receiver or amplifier. its posiible they might be shorting inside. A little frayed wire could also trigger the protect circuit in your receiver.
I hope this should solve your problem. If you still can’t resolve the issue yourself, try resetting
the AV receiver/AV amplifier before going on to opening the Receiver.
To reset the Receiver to its factory defaults, turn it on and, while holding the [VCR/DVR] button, press the [STANDBY/ON] button. "Clear" will appear on the display and the Receiver will enter Standby mode. (note that resetting your receiver will delete your custom settings as well as your radio presets).

If everything else seems all right and still your receiver shut down when you raise the volume then it possible that there are bad connections on the main board that are set in.

This would generally happen if the system is slighly old or have dry solder and when you raise up the volume. This should be a simple repair that will not require parts. If you can solder, you will be able to repair this yourself. If not, then a local service center will change the local labor rate.

Hope you can sort out your problem with the above trouble shooting. Let me know if I can guide you further.
Best of luck. Thanks for using FixYa!

DVD player and receiver will not play a dvd in surround sound ?

The dvd player is responsible for reading the surround sound track, and sending it to the receiver. First make sure you are playing the surround sound track on the dvd, many have a stereo track too. Next, try another dvd and see if you can play surround sound on that one. If you can't play surround on ANY dvd I would start looking at the audio connection from dvd to receiver. Are you using an optical cable? Red, white, and yellow RCA cables? Optical will transmit any sound over only one cable, RCA cables need one cable for each channel (LF, C, RF, LR, RR, sub.) If your connections are correct, is the receiver set to play a surround sound track? Is it set in 2 channel mode?

Stuck on standby

Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also.

try turning the unit off in standby mode then hold down the enter button and then the power button for about 10m seconds that should reset the unit depending on how new the unit is it sometimes has a digital saftey setting but i doubt that would cause it to do what you are saying
