Shuts off everytime i turn it up pass 4.

The Receiver shuts off everytime I turn the volume up to 4. The manual says the protection circuit has been activated because of a short circuit. It says I should put the unit in standby modeand then turn on to reset the protection circuit. What is standby mode? It just turn on/off I don't know what standby mode is.

Speaker wire contact with each other is the problem. Check the back of ALL SIX speakers including sub-woofer. You should find wires contacting each other. Fix that and your problem will be solved.

How do i check to see what is causing my receiver to shut off

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

The signal select is set to analog but it still turns off when the volume is slightly turned up, can you tell me why?

Sounds like the receiver is defaulting to "protect mode", this indicates that there is an electrical short present in the system, I have found that speakers or speaker wires tend to be the cause often.
Disconnect all speaker wires at the back of the receiver, turn receiver on and raise the volume control and see if the receiver still shuts down, if the receiver doesn't shut off, then one of the speakers or speaker wires are bad, reconnect one speaker at a time, raise volume and see if the speaker you connected causes the receiver to shut down, if not continue connecting the speakers one at a time, testing to see if the receiver shuts down after each speaker connected, when the receiver faults to "protect mode" again after you have connected a speaker then you know that the last speaker you connected is the "blown" or shorted speasker or wire.If the receiver still shuts off after disconnecting all speaker wires, then either one of your sources has a problem(DVD,CDplayer,cass deck,etc.) or the receiver has an internal short that will have to be repaired by a servicer.

Good Luck !

Pioneer VSX-D209 receiver shuts off when too loud

Dear Tabasco,

Your receiver is basically going into protect mode.

Just 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 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!

Onkyo TX-SR705 shuts down suddenly

Onkyo receivers have a safety circuit in them to protect the Amplifier from blowing up:

If you listen closely when it shuts down ( after a loud scene ) there is likely a loud 'Relay Click'..
If this is what is happening you might be able to verify it by turning the volume all the way 'off' and waiting for the circuit ro reset ( releasing the safety relays & returning power to the internal Amplifier ) : you should hear another click, yhen you can bring the volume back up carefully and there will be sound again.

This safety circuit trips when then Onkyo receiver detects an 'Over Current' condition on the
' Power Supply ' that feeds the internal 'Audio Amplifier'..

Generally caused by:

Improper load presented to the Amp outputs ( FL, LR, RL, RR, SUB, CENTER )
If you can ( one at a time ) turn off the SUB, Center, Fronts and Rears: trying to re-create the failure each time while you have one part of your system disabled or having their level turned way down..
You can isolate where the problem is coming from.

- any or all of these speakers being the wrong Impedence ( I.E. 4 Ohms instead of 8 Ohms )
Unless the receiver manual or the sticker near the 'speaker connetor' specifies a range or another value, you should assume 8 Ohms. Your speakers should say on the back of them.

- any of the speakers being connected in parallel ( 2 speakers to a single one speaker output ) .. Two 8 Ohm speakers connected in parallel make a 4 Ohm load to the amplifier.

- If the Suwoofer is Passive ( Not having its own power cord and amplifer ) it has a
Passive Crossover : this crossover can have its own power rating or limitation.. If it is constructed with capacitors that have too low of a working voltage, then they can saturate and the crossover itself can present a load to the amplifier that will case this 'Over Current Shut-Down'..

You user manual should detail this.

Receiver shuts off when volume raised above 10

A fuse breaker or resetting electronic componet device attaced to the audio receiver protects the amp & speakers for destruction! The quality of the amp ,spkers& spks. wires help on choosing for protection shut downs! Of course at 10 volume you risk all of the amp in the receiver , buy a higher quality brand reciever ,intergrated amp, single amp . BE CAREFUL AT THE HIGHER VOLUME RATINGS YOU RISK HEARING DAMAGE! FOR REAL!

The receiver sound shuts off

There is a problem with the receiver that is allowing DC voltage to get to the output amp section. This is detected and the protection circuit shuts down the receiver. Yamaha uses coupling capacitors between sections to prevent this. If one of these is defective, it would explain your symptom. This should be a relatively simple repair for a repair shop. Expect $10-$25 for parts plus the local labor rate.

Avr 3806 power shuts off when volume turned up

Hello david 420

It looks like your receiver's high-speed protection circuit is being activated. It is definitively not a fuse. When a fuse pops, you have to physically replace it. When the protection circuit is activated, the speaker output is cut off and the power supply indicator flashes. There are a few reasons why this happens:

1.- Your speaker wire connections are loose. Whether they are banana plugs or bare wire ends, make sure the speaker terminals on the back of your receiver are tight using clockwise turning.
2.- Verify that your speakers have an impedance between 6 and 16 ohms. Your receiver was designed to work with that impedance range. Any impedance lower than 6 ohms will activate the protection circuitry.
3.- The receiver is used at high volume levels over a long period, which results in an
extreme temperature rise. Improving the ventilation conditions around the unit might help alleviate the problem.

If after complying with these suggestions, problem is still present, you might need to have the unit checked by a professional for possible circuit failure.
Hope this helps. Let me know.

You may be using 4 ohm speakers on an 8 ohms rated amplifier, or you are trying to play the amp excessivly loud for its design apability, or the amp is not strong enough for the speakers, or there is a fault condition where the output stage is pulling too much power, and the protection circuit is kicking in, because of one of these faults. It is also possible that the protection circuit has a fault condition. A quick test,though. Disconnect ALL speaker wires from the receiver. Turn on the receiver - if the volume increase makes it cut off, the problem is definitely in the receiver. If so: You should give the amp to a qualified shop that has the proper test equipment to properly diagnose the amp for its power rating over the complete designed response, and do an evalution of its dynamic head room and dynamic range, to see if it meets specs. If something is out of specs, then it can be serviced.
