How to reset yamaha R-N402 power protection circuit
This is directly from the service manual for the R-N402: Hold the left preset button (<) and the bass (+) button and press the power button and then release. The receiver will disable the power protection and turn on in self-diagnostic mode. My device is working correctly now. :)
Power shut down due to protection circuit activated 3 times
I had the exact problem with the same model. The way to reset it to the factory default is quite easy (you will lose all previous settings). first , Make sure that it is plugged. Then press on the "info" and the "tone control" at the same time. Keep pressing for a few seconds. you will hear a "clicking" sound and the receiver will turn on.
Yamaha front panel display dim
Yamaha RX-V661 LCD / Front panel. Symptom: when you first turn iton, you can see a VERY little light but after 5 sec, you cannot see it anymoreor for most of us, we started using a flash light. Here is the summary of the solution and I know that it worksbecause I fixed it today 3/16/2011, 30 minutes ago. As many pointed out that there is a"light" 12v - 14v in the back but there is NONE. How do I know? I listened and searched andthere are NONE. The whole LCD in the front is air seal like a light bulb so itis a light bulb already. Also, you mightsee a little burn/gray smoke on the left hand side, don't worry about itbecause if the light comes on, it stills work but not enough power. If the LCDis broken, please don't try by the part and replace it because by the time youread this, the parts and labor cost as much as buying a new one (on eBay andnot Best Buy). Problem: in the middle of the unit near the back near the "surroundsound back", there are 3 capacitor rated at (2 units) 35v 220uf 85'C and(1 unit) 50v 220uf 85'C. What Yamaha did wrong, base on my guess is that theyput the 85'C too close to the heat sink. The heat causes the capacitor to slowly blown that is why you still getyour power to the LCD but not enough. Solution: remove the top, unscrew EVERYTHING in the back and there are about 20 ~ good luck. Forthose that don't have good memory, please take a picture. There are many plugs insidethat you need to unplug before you can remove 1st layer (audio/ video input)2nd player (HDMI and Optical input), the last layer you will see 3 capacitors thatare kind of "blown" up (google "bad capacitors" pictures orvideo). Remove them then replace them, which you can Google this on tube andthey should teach you how. It was very easy for me but then again, please don'ttry to do it if you cannot even change your car oil or build a computer becauseI believe that is the difficulty level. solder iron: $9-$20 get it on eBay or radioshack(2 units) 35v 220uf 105'C and (1unit) 50v 220uf 105'C or what I got was (3 units) 50v 220uf 105'CI keep the 220uf the same to besafe but increase the voltage and heat to increase the life of the capacitors.
Good luck everyone,

All of a sudden I have no sound at all regardless of what the input is. Any thoughts or has it just died. I've had this for many years.

Feb 13, 2015 - no sound on yamaha rx-530 stereo fm receiver nothing,just no soundcomming out of speakers ... Does your TV have any audio outputs such as RCA perhaps? .... Suddenly no sound is coming from my speakers except for my subwoofer. On certain settings some of the speakers work but not all of them.
Yamaha YST-MSW10 subwoofer quits after about 10 minutes
This problem can be solved by either of the following:
1/ Modify the PCBA to prevent the auto shut off feature from working. This is done by adding a 20k ohm resistor across pins 1 & 2 on the timer IC6. This resistor will prevent the timer from turning off the amp. To do this, unplug the amp. Remove the 8 screws on the perimeter of the rear of the amp. Carefully remove the rear plate. Disconnect the speaker wires at the speaker and the front panel connection on the main board. Locate IC6 on the bottom of the main board. Solder a 20k ohm resistor (1/4W) across pins 1 & 2. Pin 1 and Pin 8 are noted on the board. Be sure to insulate the leads of the resistor to prevent contact with the board. See picture. Re-assemble in reverse order.
2/ Some 5.1 channel amps allow independent control of the volume for the subwoofer in their setup. Check your amp to see if you can raise the signal level going to the subwoofer to prevent the amp from shutting off. You can then dial back the volume of the subwoofer using the volume control on the front.
It turns on and shuts off.
For my YAMAHA RX-V795a, Replaced the relay DG1U, which is controlled by the on/off button. Because the switching contacts in the relay were burned in. (Relay of which you hear the click when you switch on or off)
And everything works again. But replacing it is a bit of work...
You have to, after opening the case, among other things, loosen the screws of the main transformer and some more things, to be able to turn over the PCB on which the relay sits, to loosen the 4 solder points of the relay.
The relay is Type DG1U, 12VDC coil , switching contacts 8A 250V AC and is a Chinese brand DEC.
They are sold by Aliexpress, among others.
