My Yamaha amp turns its self off despite being connected to power! Standby button will not turn it on!

Looking at the user guide it appears that the amp has a standby mode.

See not below on turning standby on. Question can you see the standby light flashing.

I would also suggest using function on the amp to remove any possible issues with the remote.

One would expect the system to return to normal operation by pressing the power button again. If not what do you see on the display.

Note:
Press 1 to turn on the receiver.You can also turn on the receiver using 1 on the remote control. When you turn off the receiver, press 1 again. "STANDBY" flashes on the display panel. Do not disconnect the AC power cord (mains lead) while "STANDBY" is flashing. This may cause a malfunction.

HI
i think the unit needs to be set back to factory defaults
procedure is
Initializing the HTR 6130

1. Connect the power cable of this unit to the AC outlet.
2. Press the "STANDBY/ON" key while simultaneously pressing the "STRAIGHT" and "AUDIO SELECT" keys.
The self-diagnostic function is activated.
3. Select the main menu "13. FACTORY PRESET".
4. Select the "PRESET RSRV".
Hope this helps
Kind regards.

use your remote control or unplug for a couple hours and push nutton before plugging in

Have you checked the internal fuses?

This will almost certainly be a problem with the power supply, a faulty part. Unless you have experience of repairs to power supplies, due to the high voltages, I suggest you take it to your local authorised Yamaha Repair Centre.

Generally speaking, an amp protects itself from heat, shorts and overloads. Check for loose speaker connections.

Overloads can be from excessive periods of high output 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 hands-on tech.

I suggest you run self diag.  press [FM/AM] key + [Input mode] key and press the [power/standby] switch.

ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink

you'll likely have to measure the resistances of the output FETs to find a short, 

Press the Standby/On button on the remote or on the receiver (right below the Yamaha logo) to stop the audio output and display. The RX-596 goes into a low power standby mode when not in use; this allows it to respond to the remote when you press the buttons. If you want the receiver's power use to go to zero, you need to unplug it from the outlet. (You could also use a switched surge protector and push the switch to off.)

See page 9 (page 11 in the PDF) in the manual for the details on the On/Standby switch. The manual is available here: http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000057561.pdf . The page is also available here: https://www.manualslib.com/manual/197512/Yamaha-Rx-596.html?page=11#manual .

I hope this helps.

This was happening to mine also, all of a sudden. This solution came from the owners manual. Sure enough, the impedance selector was stuck in the middle , between 4 and 8 ohms....I also, made sure the speaker wires were not touching each other at the splice. Problem fixed.

The unit fails to turn on when 
STANDBY/ON is pressed, or set in 
the standby mode suddenly soon 
after the power has been turned on. 
The power cord is not plugged in or the 
plug is not completely inserted. 
The IMPEDANCE SELECTOR switch 
on the rear panel is not fully set to the 
upper or lower end. 
Firmly plug in the power cord. 
Set the switch fully to the upper or 
lower end when the unit is in the 
standby mode. 

1. The power cord is not completely insered. 2. the impedance selector switch on the rear panel is not fully set to the upper or lower end - (set it when the unit is in the standby mode) other then that, you will have to call for a service.
