Probably an output transistor issue, it will need to be serviced by a professional, especially if it turns off immediatly after you turn it on

The receiver after turning off will turn it self back on, repeatedly.


The unit is drawing too much power and is being protected by a current/temp sensitive device that shuts down to protect unit. When it cools, the power is restored until it heats up again, and the cycle continues.

Sounds like something in the power supply area is the cause of the anomaly.

How do i keep the power on when it goes out in five seconds?


You can't. It's the systems' internal safety circuit shutting it down friend

Not an expert on those machines but it sounds like the power output stage is faulty and overheating causing a shutdown.
Needs new output stage or repair ?

You turn the power on and it shuts its self back off. i need to know how to fix it.


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 '*****'. 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.

Receiver keep shutting off,power light goes off,tried rebooting but after about 20 seconds the power light goes out again


Try resolving the reason it's self-protecting.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. 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.

Yamaha HTR-6130 Receiver will not stay on! Shuts


One last try with everything disconnected!
Other than that I suspect internal surge damage.

Turns it self off with a sparking noise in the speakers


The unit has a built in protection mode if a fault occurs in the speaker wiring. If its in protection mode the power button light will flash and display goes blank. Try disconnecting all speakers and see if it stays on, if so it could be a shorted speaker wire or bad speaker.
