Fix the "no sound" issue of most Onkyo and Pioneer AV receivers

Can we get a circuit board like that?

Also helps when you turn the speaker switch on. Thanks for the tip.

Thanks man, I've just fixed the same problem on my tx 8050 with hair dryer.

Hey thank you so much this actually work and believe me I had my doubts

My onkyo HT-390 once worked with all the 5 attached boxes. But now only works with three of them. I'm not technical at all so have no clue what to change. Also, since using the sound system on my TV, steaming services like prime video and Netflix movies with dolby 5.1 don't work... So really no use of using the system. Which is just a waste... Can't find anywhere why this is an issue and if it can be resolved

Thanks for this video.
I have the same problem with my Onkyo TX-NR609. No sound and the speakers were not displayed on the front. I did the fix as you outlined and it started working again. I was very happy to not have to buy a new receiver.
However when I put the case back on and put the receiver back on the shelf the problem has reappeared. I tried the same fix again, this time making it a bit hotter and pushing down on the chip until it cooled. It did not work this time though.
The problem does seem to be the connectors on the DTS chip, as it worked initally, but maybe mine to too far gone.
Do you have any other suggestions?

To anyone who does this, take care of heating up the electrolytic caps nearby. They like to pop when they get too warm. Love seeing these simple fixes, have fixed loads of devices this way in the past. Good job!

Nice song at the end, what’s it called?

I have a denon avr-s910w that has no sound from zone 1 but zone 2 has sound ive been trying to figure this out all day any suggestions 🤔

Whats the point of hearing it if you want it to cool down.

I have an Onkyo 609 i used the hairdryer and my hair is dry but still no sound

How does he know its common? Didn't see him carrying out any tests with a suitable test equipments.

Thanks for this video😊 Now my TX-NR709 works again.😃👍

grazie funziona!!!!

Need to mark this video as unintentional ASMR. The way you talk is a trigger. Lmao 😂 probably get a lot more views

I have problems with my Onkyo tx-nr838 with no eARC sound. When I connect something on the receiver it works well. But when the sound needs to come back from the HDMI eARC that's no sound. Do you know how to fix it?

Thanks so much! This worked great for me!!

I have a Marantz SR7005 with no picture or sound and no speaker map, going to give this a try, I have nothing to loose

I have 3 onkyo.2 txnr646 and one tx nr 509. No sound with same issue.
Contacted onkyo for any kind of help ,and replied no more support for these defected units.For me when i will afford to buy a new receiver ,sure no onkyo or pioneer.

Awesome Video! Do you happen to have a way to troubleshoot a RCA RT2870r?

What if i use a hair dryer?

Wow, this actually worked…used a Dyson 😂😂

Thank you for this! It saved my amp. So glad to not have to be getting a new one and junking this one.

OI have a Onkyo TX NR757 and out of nowhere I get a blinking standby light and it wont turn on at all and sometimes it will just come on by itself and then go back to the blinking standby light

How do I get the best sound out of my subwoofer sometimes it works sometimes it doesn't

i have onkyo 309, since 7 years, , i open and have to wait , because it works 5minutes later, interestingly.

Thank you! 30 seconds with 300°C hot air helped my Onkyo NR609 to work again!!! Great diagnosis and manual! Awesome job, thank you! /Piotr from Poland

I have onkyo TX-NR609 all channel is working well but center channel noise and low sound, any advice

Interesting, is the heat application really responsible for the sound miraculously reappearing, or is it the power reset. After all the power is drained and then everything works. Other electronics do the same when a hard reset is implemented. Food for thought.

I can verify this works, and works repeatedly. I mention "repeatedly" because this solution is only temporarily. The unit will work for about a year after heating the chip. The first sign you'll have to repeat the procedure is you'll get no sound when you turn it on, but if you turn it off and then on again immediately it will work. As the problem gets worse, you'll have to leave the unit on for several minutes to warm up before restarting it works. Later it will take multiple restarts. Obviously it's a thermal problem related to that chip - the permanent solution would be to replace the chip or the entire HDMI board. That may not be possible or cost-effective now that this model is so old. And if you do replace the parts, how can you be sure you're getting a chip/board where the problem has been permanently resolved instead of someone just doing this temporary fix anyway? So this is a good way to get a few more years out of this unit.

Thank you for this!
So easy and it works perfectly again 🎉
Soo worth it buying a heatgun instead of turning it in for repairs.

Even a flood light works. Thanks for the tip.

So it worked on my Onkyo TX-NR808. I was pumped. I heated to 160F according to IR thermometer. The speakers showed up, it played for about 5 minutes but then music died. Speaker still show on display. I turn off and on and speakers don't show up.

I retried, speakers show up and play, and it seems to work until temperature comes down to 120. Speakers show available but no sound. Then off and on and speakers don't show up on display.

Any further tips?

This video helped me fix my Onkyo reviever!! Thank you so much!

Son of bitch, this worked! I was so frustrated and was already looking for replacements and like many others commenting, saved the money and am getting joy out of my system again. Many thanks!

Unfortunately his method didn't work for me, I just bought a defective unit to harvest parts from and try again

Will a small hairdryer do the job..? It gets very warm, but it didn't solve this issue..🥹

The main problem with these DTS chips is that lead free solder is used and the solder connections go dry jointed under the chip....these chips tend to run very hot with no heat sinking and the build up of dust over time makes them even hotter....i had a sound problem with my Onkyo tx nr 607 but mine was dry jointed solder on two of the power transistors.. By heating up the DTS chip with the hot gun i believe is a short term solution and will fail at some time....the best way is to resolder ball the DTS chip which i know will not be cheap and is very hard to do at home unless you know what your doing.

This worked perfect. I heated the chip up for 30-45 seconds with my heart gun set to 725 then used a carpenters pencil to lightly press down while it cooled off for roughly a minute and everything fired right up. This worked perfect, thank you!

Thank you so much! This fixed my Onkyo HT R290 receiver!

Beautiful dog.. What breed?

I have a pioneer receiver vsx524k. Rear left surround channel doesn't work anymore. What could be the problem?

I'm wondering if this chip gets hot and is a unknown problem, why isn't there a heat sink or a heat sink with a fan on top?

Fantastic. This does actually work! Would adding a passive heat-sink help?

The unintentional ASMR in this video was even more fun and tingly than watching the repair lol; Awesome!

Im having the same issue. But on the soeaker display it says M.Opt, nothing else. Would this be the same fix?

This trick usually works only temporarily and briefly, often only until you use the AV next time. If you are not getting any sound from the AV then even a quick blast with a heat gun on the DSP chip will make it work for a short period, but alas it is not a permanent fix.

So glad I found this, my 590 has been working for like 14 years, and this made it work, so excited!

Can anyone help me to reset my onkyo nr646 by remote
