Onkyo Home Theater Receiver No Sound Fix - DTS Chip Re-Flow

[@kFrederking]

Thank you very much! I'll try that on one I just bought at an "for parts" price. I'm aware that there is no guarantee that it will work on all "Onkyo malady" victims, but your brief, to-the-point, and easy-to-follow instructions give me a good shot at succeeding.

[@oliverjaksch4378]

I'm having a TX-NR414 with this "no sound" problem for many months. Haven't tried your solution for now (but will try) but I "fixed" it with another solution which is working as long as the problem exist: Power up receiver, TV and a video source, play a video (movies are a good source) and let that playing for at least 15 minutes to "heat up" the receiver. Stop the video, power off the receiver for >=10s and turn it on again (sometimes my receiver turns on by itself after a sec). Wait until (the relays?) are doing their "click" (sometimes "click---click") and voila, sound is available when starting a video again.

[@matteodorcier8184]

Thanks from Italy! This Sunday I repaired my Onkyo 818 from that issue, the temperature was raised to 260 C and it was enough to solve!

[@ginosr81]

Ciao Matteo, perdonami. Come hai risolto? Hai pulito i contatti della piedinatura del cip?

[@glittalogik]

THANK YOU. My SR-707 started needing a warm-up and power-cycle to get the speaker channels online. Only 5 minutes at first, but as time went on that grew to 10, then 20, then stopped working altogether. Invested in a flux pen and IR thermometer, blasted the DSP up to 200°C with a heat gun, left it alone to cool down below 40°C, plugged it back in and voila, good as new!

[@Upscaled_HT]

That’s awesome! Glad it worked out for you.

[@hamzamandviwala7062]

can u please guide me on how u used a flux pen, because u wouldnt have been able to drip the flux around the chip as done by "Upscaled" really nervous about doing this myself :p

[@glittalogik]

Funnily enough it started acting up again last week so I'll need to repeat the procedure, but if it doesn't work then I just have to buy a new amp, which is what I would have to do anyway.

[@glittalogik]

@@Upscaled_HT Just repeated the procedure successfully again, loving this trick 😁

[@jonliebsack9166]

Just did this to my 11 year old Onkyo tx NR 809. I used rosin flux for electronics as others mention in the comments. I also used a large heat gun took a few tries finally got it hot enough where smoke was coming out a little . It’s been working for a day. Time will tell but I’m glad to have my surround sound back.

[@Upscaled_HT]

I hope it keeps working. If it stops working, you can repeat the process and try going a little hotter for longer.

[@vortexor1]

Is it still working?

[@jonliebsack9166]

It stopped working after a month or so. I will try it again with a heat gun.

[@jonliebsack9166]

I applied solder with the heat gun for the second time. It’s working again. The circuit board it a little discolored from the heat. Didn’t use a thermometer just got it hot enough to start smoking. It’s been working after the second fix for about a week. Not sure if it’s a good idea to put a piece of aluminum on top of the chip to act as a heat shrink?

[@vortexor1]

I think its best to solder it with no clean flux and the apply a big copper heatsink and a fan which blows from top on the heatsink.... will try it in the next two weeks

[@freddis1]

I was fooled by someone from fb marketplace and bought a onkyo stereo. I did this heatgun fix and I got it working. Thank you for this video.

[@Upscaled_HT]

Glad it worked out for you!

[@freddis1]

Worked for a year. Now its dead as a Dodo.

[@Slapahojohnson1]

I just did it on the TX-NR609 and it worked! I held the heat gun above it about 3/4 of an inch for 30 seconds on about 400-500 degree setting.

[@natesdentrepair3716]

Any update so far?

[@An9eL_C]

So after 10 years of service my Onkyo TX-NR809 finally experienced the dreaded DTS chip solder symptom. Back in the day when I bought the receiver I heard about the issue and so I installed two 140mm fans on top of the receiver in a pull configuration from day one. After so many years I thought I escaped it by adding the fans but it finally gave in. The speaker icons stopped coming up and I would have to restart the unit in order to get sound. In a matter of a month it went from a restart to few minutes to about 15 mins in order to get sound. Performed this fix with flux with a paint heat gun right under 400 degrees Fahrenheit and also went overboard and added some passive aluminum coolers to every chip on the board. Turned fans around and now running in a push config. It's working like new but only time will tell (Fingers crossed). I lover this receiver to death and only wish Onkyo would have cooled the chips properly. Will keep you guys updated. Upscaled thank you so much for sharing this video it really helped...

[@Upscaled_HT]

I’m really happy it worked for you! Thank you for the thoughtful comment.

[@Fancy_PotHead]

Hey, i have the same receiver with the same issue. I'm waiting on the flux... Is it still working ?

[@An9eL_C]

@@Fancy_PotHead Funny you asked cause about a week ago it started with the no sound issue after 3 months. It needed to warm up for about 20-30 mins to get sound back. Got tired of waiting and bought a Tx-Nr 6050 for $329 open box on Ebay. Have to admit I really like it considering it's bang for the buck compared to likes of Denon and Marantz. Sucks it has no pre-outs but used a Russound ADP-1.2 line lever adapter to hook up the Crown XLI 1500 for the front towers and is working really well. Really crossing my fingers this one lasts as long or longer than then the previous one but Onkyo did add a nice cooler and fan to the chip and HDMI board. Only time will tell once again...

[@Fancy_PotHead]

@@An9eL_C damn, so it only lasted about 3 months...? I'm still gonna give it a try. Then i'll go back to a Yamaha, no way i'm buying another Onkyo 😅 This is the 2nd receiver to have the same issue. I had a Yamaha for 15 years, gave it away 10 years ago to my cousin. It's still working.

[@humblyright]

Thanks for the video. I’m gonna throw my 2 cents in because, reasons… The heat needs to be hot enough the solder begins to glimmer/shimmer at that point the solder is reflowing and you can kill the heat. Very important: do not touch, bump, or disturb the chip while the solder is reflowing/liquid. It’s nearly impossible to realign the chip pins by hand exactly to the correct pads on the board. I learned this the hard way…. I did this repair to my 609 about 2 years ago and has worked like a champ since. Until last week. Will try reflowing again. Cheers

[@Upscaled_HT]

Very good advice. Most of the time this is a long term but temporary fix. 2 years is really awesome!

I think I need to open my components now and then to clean them.. it was covered in dust inside. Anyways, I got it all cleaned up, even scrubbed the worst of it with a toothbrush & Iso 80%... but only when compressed air wasn't doing enough. I also installed the raspberry Pi heat sink you suggested, just in case. CHEERS!

I turn on the unit to do some online gaming, sometimes it works fine... and sometimes not.... the speakers array initializes and I see them on the led readout.... but I I don't hear anything from the speakers... when it's going to 'work'.. I'll hear a little tiny click or pop from the speakers. So, I can let it sit for a few minutes.. zippo.. no sound. I turn it off... turn it back on... and NOW the speaker array isn't lighting up in the display (and still no sound... durp) Buuut... if I leave it on for a few minutes.. (5-10 is good), THEN turn it off, then back on... the array comes on, I hear the tiny *pop* from my speakers, and everything works fine...

[@Upscaled_HT]

@@jamesrobinson2086 If you have nothing to lose, you can try the same procedure for more time and higher temperature. Other than that, you would probably have to take in for service but it would probably cost more to fix than what the receiver is worth, although it would be cheaper than a new 9 channel receiver. I haven't any 9 channel receivers for less than $900 these days.

[@donaldperry5863]

Make sure you use flux designed for electronic circuit boards and not the type for plumbing. The correct type has rosin in it and will gently remove oxidation on the metal pins. Plumbing flux has acid in it and will corrode the circuit board connectors and will eventually cause failure.

Is your receiver still working after your repair?

[@greenmarine5]

The problem with all newer electronics, newer meaning post 2002. There is a corporate mandate ordered by the Clinton Administration to stop using lead based solder. Companies of course had to use a different type of solder and over time it looses it's connection to the components. This was the issue with all PS3 and 4's and Xbox platforms. This is the reason why you got the red ring of death on the console. One can reheat the connection to get it to work again, but it will only last for a short time. The only way to fix the issue at the component level is to remove the solder and re apply lead based solder which some companies are using again to combat expensive recalls.

Or you could just go ahead and throw it in the trash if you want to save yourself the headache. I did try using a heat station three times and then I put it where it belongs, in the trash.I bought it for 45$ at a goodwill thinking I got a great deal because I plugged it in and everything worked great until I got home and then found out that it had no Sound. apparently, this was a common issue with many of the receivers onkyo manufacture during this time due to a DTS chip overheating .kinda sad that onkyo let quality slip away and know I wouldn’t trust buying any of their products . I did check the hours on the display and it registered it just a little over 8,000 hours. They could’ve had a recall on all of them and serviced them but like so many other manufacturers, they hide behind a limited warranty and stick the consumer faulty products.

Flussmittel ist ein chemisches Reinigungsmittel, das vor und während des Lötprozesses von elektronischen Bauteilen auf Leiterplatten verwendet wird. Flussmittel wird sowohl beim manuellen Handlöten als auch bei den verschiedenen automatisierten Prozessen verwendet, die von PCB-Auftragsherstellern verwendet werden. Der Hauptzweck des Flussmittels besteht darin, die Metalloberflächen durch Reinigen und Entfernen von Oxiden und Verunreinigungen für das Löten vorzubereiten. Oxide werden gebildet, wenn Metall der Luft ausgesetzt wird und können die Bildung guter Lötverbindungen verhindern. Das Flussmittel schützt auch die Metalloberflächen beim Löten vor Reoxidation und unterstützt den Lötprozess, indem es die Oberflächenspannung des geschmolzenen Lots verändert. www.tempoautomation.com/blog/understanding-soldering-part-4-how-to-use-flux-when-soldering-electronics/ www.amazon.com/Clean-Tacky-Soldering-Flux-Grams/dp/B07DCD9M3P/ref=sr_1_9?dchild=1&keywords=flux&qid=1627173532&sr=8-9

I just bought some flux and heatsinks and will be doing this on my unit. The thing is I don't have a heat gun and will be using an incandescent light bulb to heat up the chip instead (I've been heating the chip with this bulb to fix the unit but the issue keeps coming back if I leave it on for too long, this is why I'll be applying the flux and heatsink). How long do you think I should leave the bulb heat the chip after applying the flux around the chip? I've no expertise in soldering.

[@sachadhainaut7311]

Well, I'm about to do it now. Crossing fingers and hoping everything goes well.....

[@sachadhainaut7311]

UPDATE : I did it once using the incandescent bulb (the flat spotlight type) letting the chip and flux heat up for about 8 mins. Unfortunately that only fixed it temporarily. I cleaned the chip and surroundings and re-applied the flux around the chip and then let the lamp sit there for about 30 mins instead. I let it cool and even applied a bit of air to disperse the flux that was on top of the chip and when I saw the flux had cooled down, applied some Artic Silver Ceramique 2 thermal paste on top and applied an aluminum heatsink like the one on this video. So far it's been running great for 2 days in a row, I'll update if it stops working.

still working? Mine died yesterday.. I did the same process as you. but it lasted for about 2-3 hours... I will try with higher temperature... Mine didn't smoke. ;-)

[@Upscaled_HT]

Mine is still working. The way I saw it was I had nothing to lose and the receiver was too old to pay for a repair. The fact that it worked for a while is encouraging. I saw a video where someone went much hotter than I did so that may do it. Best of luck.

[@AndersBergh]

@@Upscaled_HT that's my thoughts as well. Used 175 Celsius for a minute.. Will up the temp and time tomorrow and see. Thanks

[@AndersBergh]

@@ramdass1989 had to increase to 260 degrees Celsius for about a minute. But the receiver is acting strange. Losses connection to PC. And when it does, I need to turn it of and on hoping for the best. Sometimes I need to pull the power cord for about 10 minutes to make it connect. If I was a hifi nerd and often listen to music or watching movies. I would buy a new one. But this reciver is used as computer /speaker amp during covid homeworking

I have same problem ONKYO TX-NR906. No sound.

[@markdol5141]

Hello everyone, I got myself an TX-NR515. It's second hand and it's been tempered with on the power supply board. Does anyone know why this is done? They took out the glass fuse, soldered a new component between the new power cable and board, and it looks like it has an IC replaced. I'm curious to why this modification is put there. I also got something strange going on, on the HDMI board. Fan is not connected and some electrical component is soldered from contact pin to the plug next to it. Also thanks for the tip, I also got no sound and I'm trying to fix it with a heat gun aswell. Found some loose solerings on the pre amp board, some transistors, so I'm gonna reflow that aswell.

What kind of flux did you use? I’m seeing many different types.

[@Upscaled_HT]

I used this one. amzn.to/3IyWmHC

[@donaldperry5863]

Make sure you use flux designed for electronic circuit boards and not the type for plumbing. The correct type has rosin in it and will gently remove oxidation on the metal pins. Plumbing flux has acid in it and will corrode the circuit board connectors and will eventually cause failure.

The temperature you are checking is in degrees Celsius or Fahrenheit?

Hi I have a TX-SR313 it has a really long delay when initially powered on. It can take up to 15-20 min before the sound kicks in. I have tried the reset and turning it on and off a few times while waiting for the sound to come on. Once it is on there are no problems works great. Could the dsp chip be the problem is this a sign of it failing ?

[@Upscaled_HT]

Just double checking but you mean 15-20 minutes not seconds right? If it’s minutes, there definitely a problem. It’s hard to say if that’s it. I did this to mine cause I had nothing to lose. The repair cost would have been way over the value of the unit so I just went for it. You could try heating a little and see if lowers the time to click on.

[@1090835tgfe45resxcvb]

@@Upscaled_HT yes 15 to 20 min

Did you fix the problem???? Did all the relays click as usual? I had the same problem and the time it took to start was getting longer and longer. It got to almost a couple of hours!! Then, one day I was watching Netflix, listening to dolby's full glory and suddenly....no more sound. Screen shows all the things it always showed. Relays are fine and switching properly at the start.

Hello! great video! Mine has a different problem (I suppose) because everything clicks and the screen shows everything it should show, but still no sound. What do you think the problem could be? Thanks!

[@Upscaled_HT]

Does your receiver have a speaker matrix on its lcd display. If it does, does it turn on? If it doesn’t have one, you may the same problem I experienced but you just can’t tell since there is no speaker matrix.

[@elblopex]

@@Upscaled_HT there's no matrix. It has 2 rectangles. One with an A and the other with a B. I tried connecting to the B output but it won't work either (I always used the A configuration because its the one with 5 channels. B config is just stereo)

[@elblopex]

How long did you hold heat gun for?

[@Upscaled_HT]

I filmed it in real time. Maybe less than a minute. I got to the temp I wanted and held it there maybe 15 seconds.

[@carnalito80]

I have Onkyo TX-NR616 and the sound is gone, so this might be the problem. Im a bit confused though, you are fixing it by heating it up? And then you add a heatsink so it make sure it doesnt overheat in the future?! So is the main problem that the chip has overheated, and the fix is to heat it up?

[@Upscaled_HT]

The problem mostly lies with heating and cooling cycles degrading the solder under the chip over time. This process reheats the solder to melting point again to make a solid connection.

[@carnalito80]

@@APPLEVALLEYTIM the chips are rare now, if you did manage to get a brand new one though, you would need to program it to your particular board if you look away from the chip up to the left there is a empty header which takes a ribbon cable, onkyo has a tool that connects to that for factory programming. The actual chips dosent really go bad. Best and permanent fix would to remove the chip and re ball it but that is a royal pain in the ar$e. Good luck!

These Onkyo A/V units are basic fire hazards. If they run so hot as to desolder connections they exceed 370 degrees f. Unplug the unit and recycle it. Buy a different brand. Mine delaminated. I didn’t trust it at that point. Give Onkyo a lesson in finance, buy a Yamaha or something else.

Its not that they get so hot so the solder melts, its the damn lead free solder that cracks after a random number of heat cycles.
