solution is the heat in the chip DSP.
Solution is to replace the DSP chip with newer revision chip.
Temporary workaround is to heat the chip. It will fail again. Quicker and quicker.

If I were you, I would look for a used model.

hello, I have had a yamaha rx-A1030 for 1 week and I am delighted, I have removed the rx-A730 and I notice quite a difference, the defective DSP chip is very difficult to change.
Would anyone have tried it with flux for tin welding?
Thank you. I love yamaha

Same problem with Yamaha RX-v679 decoder switching off and on. Unplugged all from HDMI input. Rerouted video inputs to just HDMI 4 and 5 (non HDCP 2.2) ports and everything is back to working with no decoder resets.

hi guys, i was having same issue, just got a second hand rx-v463, on acoustimass 10 series iv... I observed that this was only occuring through dvd channel (or hdmi ports) but not when the radio was on... i suspected poor hdmi cables.. also, i remembered that the hdmi1 port that i was using on my tv was 'shared' with rca inputs.. (no rca was plugged in though).. and as stupid as it might sound, i just went by trial and error and used hdmi port number 2 on tv instead, and voila, the issue was resolved.. now it could have been poor connection or what not, or the hdmi port sharing itself.. but this is working for me right now, until.. :D cheers. try changing ports and/ or cables and see, and share your results.. try other sources of input to confirm if issue is amp related, speakers or cable.. i hope this helps.

My Yamaha RX-V683BL purchased in 2018 just started this. I was watching a movie on Netflix and the audio just stopped. The speaker indicators blinked off. I "jumped back" the movie 10 seconds and the audio restarted. This happened intermittently throughout the movie. It had not happened before. Is this something that will get worse?

Hi,

I am hoping someone could help me with this issue. I have had my receiver for just over two years now. The problem started small, but has gradually gotten worse and worse.

Basically, the audio cuts out for a few seconds and then returns. Sometimes it does so every 10 minutes, sometimes every 30 seconds. When it does cut out, the speaker icons disappear from the display of the receiver, and then return again just before the audio plays.

I have tried using headphones, instead of speakers (speakers unplugged) - same problem.
I have tried playing music through Ethernet (HDMI unplugged) - same problem.
I have placed the unit in a different location - same problem.
I have power it from a different wall socket - same problem.
It worked perfectly for two years...

Rarely, there is a subtle noise, like someone crumpling a plastic shopping bag, or like firecrackers, coming from the speakers.

I have sent it in for repairs twice, but the Yamaha engineers say that the unit is working perfectly. The second time, the engineer said he tried it at his home for over a week, and he didn't have any issues.

After they returned it, each time it is fine for a day or two, and then the audio issues start again. Which leaves me to believe it must be something in my home.

Has anyone else had an issue like this, or know what else I could try to resolve it? Any forum searches I have done, refer to HDMI issue, which I bypassed, or TV Boxes, which I don't have connected at the moment.

The engineer said, he could replace the DSP board (I think that's what he means. I am in Taiwan, and the engineer only speaks Chinese) But he said that could be expensive.

Thanks in advance!
Same problem with the Yamaha SR- C20 FROM DAY ONE.

Mine is an RX-A840 with similar behavior. The only way for me to keep the audio flowing, is to have my source connected through analog ports and put it in Pure Direct mode. Any other combination ( SPDIF, HDMI with or without Pure Direct mode and analog without PD mode), brings the problem back (Audio & L R lights simultaneously switching off/on).

The only other difference I noticed is that it takes longer and shows less frequent with analog connections. Through digital, it shows almost immediately.

I have been able to reproduce it a couple of times with some slamming, which could mean that there is a bad connection somewhere.

I'm curious if others are able to reproduce and confirm this. And if so, is replacing the DSP chip the way to go.

Hope this helps to find the cause and solution.

Same problem with the tsr-7810 but the fix was easy after just poking around in the settings for a few. Go to settings then sound then scroll down to virtual surround back speaker and be sure its turned on. For me it was problem solved and the problem i was having is the same as what I've read here. Try it let us know how it worked out.

I'm not sure I understand what you mean by scrolling down through settings like that. No such option on my system afaik. Think yours is running different software. Wouldn't add up either or would not be the whole story since the problem in my case was sensitive to slamming the case. I have been able to reproduce it a couple of times this way till it stopped showing up and haven't been showing up ever since. This, and the sensitivity to heating up / cooling down, points to a bad contact somewhere. Maybe indeed one of the legs of the DSP chip itself.

I've seen some examples of people doing some refluxing on these kinds of chips and even the whole DSP board. I don't have the right equipment for that anymore, but it looks doable and should be easier than replacement. At the moment I can only enjoy a beautiful working and sounding AV system. As soon as the problem comes back I'll try to poke this DSP chip/board directly to find out if my guess is right.
