The unit has an internal problem and is shutting down. This is also known as protect mode. Since there is nothing connected at all, the most common cause of this is shoerted output transistors. Expect a parts cost in the $40 range plus the local labor rate for the repair cost. Let me know if you want to attempt the repair.

My receiver just shut off while watching a movie and won't turn back on. I checked the only fuse i could find. Where to go from here.


Press and hold the "straight" and "Tone control" buttons and press power. This should release the protect lock that the receiver is in. If it shuts back off immediately, then you most likely have a blown amp that will need to be repaired.

I have a Yamaha rx-v3000 receiver that lately has begun shutting itself off and then I have to keep hitting the power button until it finally stays on again. This may take 20 times of pushing the power...


Maybe a cool-down is what really fixes it, huh?

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Cost is way out of scope for us to predict.

My amp cuts off every time I turn it on.. even with n without the wires connected!!!! N if I do cut it on the volume is on -7 n cuts off automatically n won't come back on unless I replug n plug it up...


Does the "protect" light turn's on when it shuts off? If it does then theres a problem with your wiring or worse this might be a Thermal Protect. The amp shuts off because its lacking of voltage from your battery & alternator. Post your system so i could help you further.

I have an Onkyo AV Receiver and every time I push a button(input selector, turn speakers on or off...anything) the whole system shuts off but i can turn it back on immediately and it's fine till I hit...


Onkyo & Harmon Kardon it a very nice unit and it built very professionaly and very sensitve unit. Its very important that you make sure the correct pole is connect correctly when it come to speakers. the unit come with resetable breakers inside the receiver (safety protection) so you wont blow or short the unit if not connected up correctly. when wiring speakers up from an to the receiver you have to make sure the poles are hook up correctly. positve speaker wire go straight to positive plug behind the receiver same as negative. the speaker wires should have some kind of making on it to mark as either positive or negative. try that and see if that help, if nedd more help.

Yamaha rx-v461 not working


you have a faulty circuit somewhere, whether its in speaker wiring, or power source, i dont know, but your reciever has an automatic circuit breaker in it for protection, and a faulty circuit will trip it, i would assume it is a power source problem since it wont turn back on, check wiring, plugs and look around, and smell for burnt, or hot components.

My Yamaha HTR-6050 shuts off at random times and says "Check SP Cable"


That is a check the speaker wire error, caused by a short or perceived short. If you look at the back of the receiver you may see 1 strand of the wire loose, they are very hard to see sometimes. You may use banana plugs as it is painful to get everything hooked up without a few loose strands.

If there is still the issue check your speaker connections for the same issue. If they are in ceiling/wall speakers disconnect them all then plug them in one at a time to narrow it down.

If the issue persists perhaps one of your speaker wires has a short somewhere, could be a misplaced drywall screw from hanging a picture, or a carpet tack strip, or a pet deciding it was a nice chew toy.

If you are completely sure it is none of those then I would say it is a bad speaker or receiver. Try changing in and out known good speakers/receivers if you have access to them to see which one it is.

Good luck

Immediate shut


Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck

Yahama receiver Rx-630 not working


The problem might be caused by two major circumstances. 1)Touching wires 2)Overheating. I suggest you unplug all wires connected to the amp then turn on the amp. If it gets turned on then we know that the problem is that you have touching wires. If there is a short circuit somewhere, get rid of it. The ventilation is another important issue that you have to pay attention. It simply causes overheating.
