Unfortunately it is not quite that simple. There are a number of reasons for a protection shutdown. See the link below for the generic explanation of what is happening. Post any additional questions here. In the meantime, I'll try to locate the schematic so I can post the most common failure parts.

When playing DVD, it's sometimes display 'PROTECT' and stop playing.


Check if you receive the error when playing any DVD in particular.

What happens when you take out the DVD and try playing it again? Does it play

This protector error denotes several possible problems. Heat, volume level and incorrect DVD settings may be the cause of the problem. The following steps will help you correct your problem and rid your amp of its "Protector" error.

  • Examine your volume setting to be certain that your volume knob is not at maximum. Having your volume cranked too high can cause the capacitors to overheat, shutting down the receiver.
  • Unplug your receiver and disconnect your speakers from the terminals on the back. This will allow you to determine if the error is internal. Plug your receiver back in and look for the same error message. If you continue to get the protector error without having your speakers connected, you may have an internal electrical problem. In this case, contact Sony about finding a repair center.
  • Reconnect your speakers one at a time. The order of connection doesn't matter. When reconnecting, be sure that you do not have your positive and negative speaker wires crossed in any way. After each connection, test your amp by running it with a source. Give each speaker a few minutes of power before connecting the next one. This will help you isolate which speaker terminal is causing the error. When the protector error returns, take note of which speaker connection caused it. Check this speaker wire for shorts or torn shielding.
  • Examine your ohm rating of your speakers if you have no shorts or wiring issues. Sony receivers are not compatible with speakers lower than 4 ohms. Connecting a lower ohm-rated speaker will cause an error.
  • Turn off the surround sound option if you have both your A and B position speakers in use.
  • Keep your receiver well ventilated. Overheating due to poor ventilation can also cause Protector errors.
  • Examine the sampling frequency of your connected DVD player. If the error only occurs when you watch a DVD, the sampling frequency of the DVD player may be set too high. Check the sampling rating in your receiver's manual and in the DVD player

Just bought yamaha rx-v467 reciever, it worked for 2 mins then it trips out, wired all surround sound correctly. now unit only turns on for 2 secs then turns off. it does it 3 times and then you have to...


This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic. 1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

It keeps blinking protetor


The protector circuit protects your amplifier from shorted speakers . One of your speakers , or more speakers are shorted out . To figure it out easily follow these instructions . Turn the unit off . Now unplug all of the speaker wire connections from the back of the unit . Turn the unit on . Make sure the volume is turned all the way down . The protector light should not light up . If it does , the problem is inside the unit itself and we'll have to be repaired at the shop . If the protector light is off than continue on as follows . Connect the speakers one at a time to the unit . Each time you connect a speaker , turn the volume control up and back down making sure the protector light does not come on . When you connect the bad speaker , the protection light should come on . Whichever speaker makes the lights come on when connected is the bad speaker and should be replaced .

I have a yamaha R-V703 receiver and it has worked well until today. It was turned up loud and all of a sudden kicked off. Now every time it is turned on and the volume knob is turned it turns the unit off....


Make sure the speakers are connected correctly. Something inside overloaded and could have blew a fuse or is in protection mode. Before taking the unit in for servicing or attempting to opening it, I suggest checking that the speaker wires are connected correctly to your receiver in the back. Even one loose strand of speaker wire touching the steel panel will shut your receiver off when the volume is turned up. If that isn't the problem, then try to unplug all the speakers and test it again to confirm that the speakers are not preventing the receiver from functioning properly. Lastly, if no success, wait a while until the unit cools then try again without speakers connected.

When the protect lite comes on and the sound cuts out , what is it protecting ? the speakers or itself? thank you.


"Protect" is saving both really - but primarily the amplifier. The protector guards against shorted speaker wires, damaged and mismatched speakers, etc. If the amp is allowed to operate for a long enough time in this condition, permanent damage may result.

Usually, the lower the volume the amp is operated at will allow it to be played longer before the protect indicator comes on again. If played at a high level of volume, the protector will likely activate very quickly. Sometimes, damage to one or more output transistors seems to prevent the balance control from working correctly. You may find that you can only play the right channel at normal volume and the left is significantly softer - or not audible at all. This can be a fairly expensive repair - depending on the number of transistors to be replaced. Some factory service centers offer a flat rate repairs for this indication. Shipping these devices can be fairly costly however.

I hope this helps.

Yamaha RX-V1400 receiver powers off, in case it becomes louder


Hey, yeah that can be frustrating.

When you turn it up do you hear the relay or a clicking sound, then you turn it on and it comes back below the +2db?

Try unplugging All the speaker wires from the unit. Turn on the unit and listen for the click.
after the click, turn it up past the 2+ db mark and see if you hear it click or shut down. If it did not click off, then suspect a shorted crossover on one of your speakers.
2nd test is to plug in One speaker, and test it at high volume, it will not harm it. If it shuts off disconnect that speaker and try another. Only one at a time.
If it works at high volume, you need to isolate one of your speakers and i bet it has a shorted crossover that has been cooked. P.S. If one is bad, suspect they will fail at a later date.
If they all fail, use a friends speaker and try it before sending it to a repair shop.

P.S. i found one on ebay i think you can get for under $100 bucks in the box.

Yamaha rx-v661 unsolved speaker wiring error


1. Try running the auto setup without the sub. ( is it a powered sub {the sub has its own amp on the back} or is a NON powered sub that is driven off the speaker jacks of the Yamaha receiver. )

If the sub is powered, and connected to the Amp via the RCA cable from the " sub out " jack, chances are you either have a defective sub or a gound loop.


Good luck...Rob
