SOURCE: Yamaha RX-V596 Receive turns off after pressing Power

Sometimes the receivers turn off if the speakers are shorted in order to protect the AMP circuit. So try this - 1. Disconnect all cables (speakers), inputs from Tape Deck, VCR and other input devices), sub-woofers, rear speakers all. Except the AC power cord. Then turn it ON and see if it stays on. If it still has the same problem, then most probably your power circuit inside the receiver has a problem - like a shorted Capacitor or diode etc. Based on how technical you can be and what resources and time you want to spend, this is repairable. But based on the price of a receivers these days, it is not worth. Good Luck!

SOURCE: Won't stay powered on

There is a relay right next to the fuses on the inside dg1u it says on the top. I cleaned it and pressed down firmly on it and it seem to have fixed it. It fired up for the first time.. The relay might need to be replaced if this doesnt work for ya.

SOURCE: Yamaha RX-V1 Power

Got the same problem and did some searching.
Strange thing is that next day the amp works fine.
This is what I found on http://www.forums.hcsd.com.au/Blah.pl?m-1210733289/s-8/

SYMPTOM: The power cannot be turned on, or the protection circuit is activated to turn off the power.
CAUSE: Fluid leakage occurs from the backup capacitor C633 0.047F 5.5V (C662 in the case of RX-V3000/DSP-AX2) on the Function PCB and causes a short with the adjacent components and between patterns, resulting in operation of the protection circuit. Fluid leakage tends to occur with this capacitor particularly with high internal cabinet temperatures, with or without the power on. Often, the leakage is only visible with very careful inspection.

SOLUTION: Two types of backup capacitors are now available with a longer expected service life. When servicing, thoroughly clean the leaked fluid from the PCB and from under any nearby components before replacing the capacitor. There are models other than those mentioned above that use the subject backup capacitor. Check them for fluid leakage and replace the capacitor as needed.

Does the reciever have separate speaker switches?
Try turning off the speakers and turning on the amp.
If it doesnt have speaker switches , make sure ALL the speakers are connected at both ends and try turning on the amp again.

SOURCE: Yamaha Rx-v730 - only hear "click" when try to turn it on

That may due to a bad power transistor, huge current flows when it's powered up, protection circuit kicks in and switch off the unit. Get to repair shop for check up and replacement.

How do you reset a yamaha rx-v730 the protection switch on the relay keeps tripping


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 '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.

Check for loose speaker connections at the speaker as a root cause for ntermittent shutdown.

The REC OUT jacks on the back are usually the best as they are not affected by the system volume. You'll need an RCA L and R Male to Headphone (1/4" female) adapter (available at Radio Shack and online sellers).
