How do I reset the protection circuitry on Yamaha RX-A820?

press and hold the 'tone control' and 'info' buttons and press power. This will release the protect. The first thing that show on the display will be the protect code to tell you why it shut down. If it turns right back off, then you most likely have a short in the amp that will need to be repaired.

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. :)

How to hook up subwoofer for yamaha RX-496 2channels receiver

You need to connect the subwoofer to your receiver using the speaker wire connections on the rear of the receiver. Take the speaker input from the subwoofer to the A or B speaker terminals on the rear of the AV receiver. Then take the speaker outputs from the sub and connect to the main speaker terminals. Really you need to buy a receiver with a sub out to do it properly. Sell this one and buy another.

Yamaha S115V speakers making machine gun like sound when mic volume is turned up.

You need to check your specs on the amp and preamp. There is a mismatch with impedance or you are overdriving the amp input and internal feedback circuit is trying to clamp it and causes that sound. It is known as motorboating.

Rav285 receiver. When the tv and receiver are turned on, why is there no sound?

The audio outputs on the rear of the TV (if present) should be connected to the audio inputs on the rear of the receiver. From your description, it seems the present connection is incorrect.

Yamaha RX-V773 receiver takes long time to warm up before I get sound. The time has increased to over 10 minutes. Any ideas what could be wrong

Hi. I have rxv773 and it had the same problem. If u turn it on and after reley clicking 2 times fast and 1 time after about 8 seconds, look at the display if you see speaker ikons. If u don't see them and there is no sound. You wait those 10 minutes when sound comes back and look if the icons apear at the same time you got sound. If that is the case, you have bad DSP chip inside on the hdmi board. You could open the yamaha cover and see it right away on the top board at the right side. The chip is D80YK113CPTP4. That is the bad one. If you apply a heat for about 20 to 30 seconds with the heat gun at medium settings, you could fix the problem for a day or two or maybe a month. You need to replace the chip with newer one D80YK113DPTP4 . That dptp4 is updatet chip from cptp4. You can find those on aliexpress.

My HTR Yamaha 5860 shuts off as soon as I turn it on.

I have seen several things that can cause this. One is a capacitor that holds the memory in the cpu. Another is a voltage regulator and then there are failures in the final amplifier transistors
