Onkyo TX-NR Receiver DTS chip Reflow Procedure

This unit has more than one issue. The sound matrix from the amp is not working due to the DTS chip desoldering from the board. It causes cold solder joints and in some cases will come on if the chip is heated. The chip expands with heat so cooling it can also make them come on when they shrink. This one also has a low voltage power supply issue. 12v and 5v section issues. Being too high! I will go back to the drawing board to get that issue fixed, then the DTS chip should be okay. I can get the chip and can replace it, but I also don't want to do that until I'm absolutely sure that is the issue. The chip is bad from either taking a hit from heat or from me working on it. The main issues at this point are the low voltage supply problems.

[@Craven112]

Thank you so much for this! I was about to throw out my TX-NR616 but thanks to you I was able to fix it quite easily. I added a small Raspberry Pi heatsink to it, so hopefully it lasts.

[@john6pack]

To be clear, I used a flux pen around the edges of the DTS chip. I don't have a temp controlled heat gun so I just used the one I have and turned it on and off until I could see the flux starting to smoke. I used Isopropyl alcohol to clear the flux but I always buy 91% pure alcohol for electronics work (and all purposes) instead of the regular ~70%, that way it has less water in it and more quickly evaporates and cleans up faster. Anyway, otherwise followed Shane's instructions and it worked on the first try! Thanks Shane!

[@bassinbillRC5300]

SUCCESS!!!! From another youtube video I heated up the CPU chip labeled DTS Dolby digital to only 185 degrees F. No luck. I searched for another video if there was something I could do differently. I happened onto this gentleman's video and applied heat from my lowest speed of my heat gun and using my laser temp thermometer. I got the chip up to 480 degrees F. I allowed it to cool down to the same temp of other chips on the HDMI board. I turned on the unit after plugging it back into the wall. Two clicks upon pressing the power/standby button, then waited another 4 to 5 seconds to hear another double click and low and behold the speaker position diagram or display which NEVER came on before appeared. This part of the display was not lit in the photograph used by the seller of this unit on Facebook marketplace.

[@nagygabor7432]

Hi! I also have an Onkyo TX-NR414 amplifier. After switching on, there is no sound. My question would be, how long did you heat the chip? In addition to sound, there is no network and USB.

[@johneyre4703]

Thanks for video, saw a few of these. I had a 616 with no sound, donated to my MakerSpace. Tried the hair dryer option, worked for a few minutes, then made a card-cutout wrapped with foil and placed over the dts chip, so the chip was the only thing showing. Hit it with a workshop heat gun, didn't work first time, but removed the foil cover and tried again, not for a long time, but it worked. Still OK after three days. It is a great piece of A-V equipment. Cheers, John

[@ShaneCarles]

Awesome. I'm glad you got it running. It takes enough heat to melt the solder under the chip. The foil was blocking that heat from getting to the surface like it needed to.

[@donkunze3377]

Thanks dude. 10 minutes later and we're up and running.

[@AliBaba-ig3mz]

Bit sceptical on this..as tx-nr609 was also having issues reading usb drive...stuck on initializing. Also have no sound problem. Followed what you did...flux on the dts chip and heated with heat gun...IT WORKS!!! Will see how long this fix will last ....Thank you for posting video.

[@ninalli]

Hey Shane, I am really sorry to hear that you were effected by the floods. Its such a shame to hear that after a fantastic instructional video you have uploaded. Keep up the good work and I am looking forward to learning how to replace the caps on my TX-SR875 as now its failing. Cheers.

[@ShaneCarles]

Thank you for the kind words. It really means a lot to me. Replacing caps is really easy. I usually try to find the best brand cap and replace with the same values. These boards have SMD caps so if you can't find the right voltage they may not line up if you go up in voltage which is okay function wise, but since they are SMD the caps have to line up with the soldering pads.

Hi Matthew Lau!

[@nateh1399]

Great content . I used your method to fix two receivers. Onkyo 707 and Integra DTR 40.1. Thanks

[@billysgeo]

My Onkyo TX-515 is playing sound from radio, from network sources and form a USB dongle... but does not output sound from any of the analog RCA inputs... any ideas?

[@TheBecfoxy]

Yep, totally followed this video and fixed my Onkyo!!! Thanks heaps Shane, from 🇦🇺

[@ShaneCarles]

Very Awesome! Let's hope it holds up for a long time. Otherwise, the chip would need to be replaced with the new style package.

[@gabrielmiskowicz3845]

Thank you Shane. Good job. I reflowed dsp chip and tx-nr818 alived. I used soldering flux (polish - pasta lutownicza) and everything is fine.

[@ShaneCarles]

Welcome! Glad I could help

[@jeffbuggica1434]

Thank you for posting the video. This helped me to fix my in-laws Onkyo Ht-693. I heated up both of the DTS chips with flux and a heat gun that I bought at Home Depot following your direction. I cleaned it up with electronics contact cleaner and viola, it started right back up! My father in-law is going to be so impressed (probably not, but we can dream, can't we).

[@ShaneCarles]

You're welcome! Something weird is going on with KZbin right now. Your comment is the only one showing right now. This video has many comments on it since I posted it. I wonder where they went.

[@ShaneCarles]

Because we discuss many things in those comments about these receivers.

[@ShaneCarles]

Got'em. Took me refreshing Chrome a couple of times. I'm glad you got it working. It could fail again though. What I was doing to make them last longer, is to glue a heat sink onto the DTS chips. With the unit on and the top off (be careful not to touch any 110v wires that should be on the right side looking at the front) touch the DTS chips to see how hot they get. If they are too hot to touch or it is more than just warm, heat sink them. I used epoxy to glue them on with. A very thin dot in the center of the chip, then press the heat sink on to spread the glue thin.

[@FnTearable]

btw op says he uses jb weld and then says lets hope there isnt a fire.... use a small well finned heat sink and thermal paste infact i used one the size he holds up last is a bit big............. that i salvaged off a south-bridge... and 420c from a heat gun for about 15 to 30 sec is fine across the chip. then let it coooooooooooooool. seriously leave it . bam test it and if it works rejoice mofos!!!!!!!!!!!!!!

[@AAI30]

This is happening to my Yamaha RX-v677. when I heat the chip up, sound then comes. I will try and reflow it. Great video Shane!

[@MichaelD-dp2gp]

Well can't believe that worked! Thank you! Didn't use Flux. Used a heat gun and took me only a few minutes

[@ShaneCarles]

Freaking awesome! Let's hope it lasts.

[@robertmackiewicz6232]

This fix worked on my 2009 tx nr3007 no flux used. Heat gun on 800 for 10 seconds or so until I could smell solder

[@natasharamm6270]

Shane what would you charge to fix an hdmi board or do you have one i can buy for a onkyo tx-nr3010 have it where the speaker matrix doesn't always appear

[@idonegotold]

Mine loses sound after it's been turned off for awhile. It has to be on for 5-10 minutes, then switched off and back on before I get sound. Same issue? It's an Onkyo HT-R391

[@textor33]

When I play mine at low volume that that whole board gets warm , and the 2 fans dont seem to come on .Any advice?

i have a onkyo lap-301 that works puts sound out to the subwoofer but the speakers make a clicking sound come from it any help would be grateful

[@johnbigboote]

Excellent video and tutorial. I have a Denon AVR with similar no-audio issues, from either analog (tuner, RCA cables) or any digital sources. All other functions seem to work (OSD, display, etc. onboard diagnostics all seem fine except "AUDIO PACKET DOES NOT COME FROM SOURCE." So I assume it's a similar issue to the Onkyo. Is a DAC or DSP still part of the signal flow even with analog sources? I am preparing to attempt a reflow but I'm not sure which chip is the most likely culprit. Advice on a good way to diagnose? Turn it on and see what gets hottest and start there? From what I can figure from the service flowcharts, it's either the DAC, the DSP, the input selector chip, or the volume control chip. is the Onkyo DTS chip their DSP, or their DAC? Thanks for any advice!

[@younessBa]

Hi Shane and Thanks for the video. on my case when the sound stop to be heard. I also lost the icons of the 5 speakers in the display screen. so when I heat the chip with heatgun the 5 icons of my speaks comes back but with no sound.. do you think it the other CARD that needs to be heated ? ( the one with the speaker connectors ) ? any other recommandation please ? because by logic , If the speaker's icons comes back this means that I m supposed to have sound, but it s not the case . Please Help .

[@ktolon]

i have a tx nr3008 that has had the hdmi board replaced in the past but recently has developed random crackling hissing and poping on the front left channel using any input, ive checked wires ect. ,i believe its a cap or something in the amp .any ideas? eventually i was going to swap the channel boards around and see if the issue moves.

Nice video, I purchased my first Onkyo in January and come February I have sound problems, sometimes there is no sound other time there is sound, I still have the speaker matrix on the display, if I have 2 clicks after turning on there is sound, but one click no sound.

[@SOLITARYMAN474]

are there any Authorized Onkyo repair centers in South Florida to fix the sound on my TX-NR609?

Hi Shane, I am having Only I HT-R558 and recently due high power fluctuations hdmi out has burst and could see smoke stains around the board. When I took the unit to service centre they had told need to replace motherboard. Not sure why motherboard unit. Could you plz help me how to get the unit service and I I get spare from onkyo. I am from India and bangalore. Plz help

[@pyrom1454]

Hi, finally how did you end up doing to repair the amp? I have the same problem too, the chip that does not seem to heat up after trying to heat it to rebuild the solder. thank you in advance

[@soundshaper3]

My DTS chip has a sticker on it saying "new", so maybe it's been replaced before or is a new generation of chip? In any event, this trick worked for me and got my HT-R990 back up and running momentarily, just ordered some flux so I can see if I can make it a more permanent fix

[@StinkyDog1971]

I have a Onkyo TX-NR 717 that may have had this done on warranty a few years back. The issue now is no HDMI video out put. It's not a an issue with the cables as I am using a manual HDMI switch until I get this solved/fixed. Audio works fine and the matrix is displayed fine. It is also started nagging for firmware updates. I did via network, and USB and get an error every time, so I stop trying. I did hard reset until cleared and restarted no change to video or update. I opened it up and that DTS chip has a sticker that says "new". Ideas? I have a reflow gun, but don't want to hit the DTS chip and risk losing audio. I like the 3 zone on this unit and finding a new one with this is expensive. Great Video!

[@ShaneCarles]

Check the HDMI sockets for any that may have cracked the HDMI board or damaged the pins inside of the sockets.

[@MattiaRaggiDrum]

Good evening and congratulations for the video. I take this opportunity to ask you a question. I have an onkyo sv454 amplifier that has a problem. In FM radio the speakers sound good while if I put on video1,2,3 or CD and try to reproduce the audio coming from the various sources the left channel does not play, only the right works. If I put it on the radio it works perfectly. What should I check once opened? thanks and to the next video. ps: If I leave it unplugged for a few days and then mention it, both speakers work for a few minutes in every situation. What can it be? Sorry my english but i'm italian. thank you

[@MarcoS-xe7wd]

Are all TI DSP Chip the same/compatible? I have an old(10 +Yrs) Onkyo HT-RC270. I checked Ebay and they are selling these chips but the numbers are not the same as mine. The description/number on mine is D830K138ZKB83 YF-04A2C3W GI

[@kevinrhug]

Thanks for the video. I have a tx-NR 717. It jas not worked for a looong time. It shows that it is working properly BUT no audio. I could have sent it back and repaired under warranty had I known. I just ordered a heat gun. We'll see what happens.

[@AJ-uw9oe]

An electronic services guy checked it out and said the chip did not work any more and so I think it was already moved out of place. But I wanted to try the reflow and did it with a coin on top, and it did heat well but I accidentally touched the coin and the chip moved out and now i can't get it back in place unfortunately.

[@dixiedoctor2563]

A gentleman said he was able to repair his unit by changing all the diodes on the drive board, the problem with reflowing is that the procedure deteriorates the chip, if it is overheating it is probably because it is short-circuited, the diodes on the drive board cope directly with the electric current distribution in the analog phase of the circuit, these signals must go directly to the DTS chip which causes the overheating and the soldering problem, for this reason if you do the reflow procedure it will not solve, it will be just a palliative, check the drive board.

[@TweakedSystems]

I think I burned up my chip,now when I turn on the receiver it shows AMP Speaker first. then the display.

Why would my tx-nr 1010 be getting sound from FM radio and component in, but no hdmi image to my monitor? I have had it with Onkyo, having used this brand for 25+ years. This is the second HDMI board that has bit the dust for this receiver. The front panel LCD doesn't display either. Pfft!

[@NelsonBigGunP200Fan]

i've had a few 709's and 2 809's with this issue, and I am bidding on a 3009 on ebay wtih the same no sound issue. Onkyo fixed them all free even send me a box and packing materials, The repair center is only a state away. took less than a week.

[@railtonsilva2009]

Shane Carles, my AV is a TX-SR606 has sound in Zone 2, however in the main there is no sound, can be problems in the chipset too? Thank you.

[@ShaneCarles]

I doubt it's the chip set. Check if that system has separate outputs for Zone 1. You could have a bad output in Zone 1 if there are separate outputs for Zone 2.

[@TheOpenation]

Hi Shane, I have an onkyo tx-sr705 that is making weird sounds like bombs in my speakers do you have any idea what that might be. thank you so much.

[@ShaneCarles]

Can you make a audio recording with a cell phone and email that to me or link it with Google Drive? I need to hear it to be able to diagnose. But if I had to guess, anything from the high output caps to the output transistor finals or even the transformer which is very unlikely but could be with a big enough surge. my email address is [e-mail]

I fallowed your instructions, first time used a hairdryer and UE22 error went away, however, still not sound. Buy flux and a heat gun and tried again. No error, I can hear clicking every-time I change input but not sound coming out. Everything looks working properly. HDMI inputs and output are working. Do you think I have to replace the dts chip? Or is maybe something in the other board for sound? Thanks again! From The Dominican Republic!!! Nice place for vacation with all inclusive hotels!!

[@premiere3610]

thank you

[@ruifaias4058]

great video!!! just one thing, the over heat isn't caused by the chip itself but rather the power supply that sits under the hdmi board. i dont know why onkyo do not use some fan to cool it down. the power supply uses rectifiers and regulators that get really hot, and they literaly cook the hdmi board. my onkyo tx-sr 607 had similar issue because of it. the caps got dry really fast. my pioneer vsx 921-k have the same chip and no problems at all, just because the unit runs way cooler than the onkyo. either way i might buy some onkyo with this fault and repair it myself

[@ShaneCarles]

These receivers do have fans. This one has 2. A push and a pull fan. But to tell you the truth, I've NEVER heard them come on but that could be because the sound was so LOUD from these receivers, I probably couldn't hear the fan come on. I needed to test one of these with the top off and running at 75% volume on 7 Polk tower speakers. Then take a look at the heat situation while I jam.

[@ruifaias4058]

the problem is that the power supply gets hot even with no sound output, at least in my older onkyo. if it has a fan just for the power amplifier, then the hdmi will always get super hot. if it ouver heats even with fans, then onkyo have a really bad design on this units

[@danmorgan4934]

Actually, it's both. The DTS chip is being supplied too much voltage due to the design of the board, AND the heat from the PSU board underneath further accelerates the problem. My TX-NR515 lasted 6 years before giving up the ghost, others have had their amps last for as little as 2 years. I'm sending mine away to see if it can be repaired, if not, I'll try the method in the video, in addition to adding some heatsinks to the larger chips on the board. The comment in the video about the fan on the heatsink is total tosh though. The fan will help wick the heat out of the heatsink. Why do you think PC-CPU coolers have had fans for the last 30-odd years, if it doesn't work?

[@totalbliss1]

You sound like a mad genius. I thoroughly enjoyed watching this video and I'm sure I could learn a lot from you (subsribed). Please continue making these videos and hope you get back on your feet from the flood.

[@earlyculyer4103]

Why don't you use thermal grease underneath the heat sink like a CPU? That stuff is sticky enough where you don't need JB welding

[@Ben-rj7xs]

Hello, I just picked up a beautiful Onkyo TX-NR-616 the issue is it has no sound at all. Does this model have a DSP chip as well. If so would you know the location of the chip. I would like to try and reflow the solder using flux. I appreciate any advice you can offer me. Thank you. Ben

[@Craven112]

I just fixed my TX-NR616, so it's worth trying. The chip is located towards the back right. Just to the left of the right fan bracket arm. It's a square chip with no legs.

[@olafnewz]

Can I clarify whether the FM receiver does not go through this DTS chip? (seems reasonable) My TX-SR313 has audio when using the radio, but none of the HDMI channels, so I suspect the DTS chip. But just wanted to clarify before I start with the reflow tool. Thanks, Anton

[@ShaneCarles]

If the radio receiver is driving an analog signal than no, it doesn't run through the DTS chip for audio conversion. You may hear a relay click when switching to the radio in that case. I've never thought about that as a test but then again none of the other analog inputs or outputs would work when the DTS chips do this on other models. The key thing to look for is the speaker matrix. The left part of the display that shows what channels are active. If that's coming up, then the DTS chip may be okay. I would try just warming the chip up at first to see if you get a change before going ahead with the reflow.

[@olafnewz]

@@ShaneCarles Thank you. I don't believe me model has that individual speaker display but I will try some non-HDMI inputs and try gently heating the IC first.

[@variedades4848]

Most of these devices crash in the BGA DTS and make reflow work again, but after a while it goes back, I had not seen anyone changing components, I think that here in Brazil some technicians act in bad faith and do this or change the chip or even change, change the capacitors and charge the value of the chip.

[@TheOpenation]

I have an issue that It might not be heat related... What I am experiencing could be the old DTS HD-Master bomb issue. The DTS DSP decoder has some bugs in its programming. When playing back some movies I get a "chirp" or more catastrophic, a loud "pop", depending on what is sent to the decoder. Can you please let me know how to fix it please ? Thank you

[@ShaneCarles]

Have you tried doing a reset or updating the firmware for the Onkyo TX-SR705?

[@ShaneCarles]

I see it doesn't have networking. Does it have a USB port on it?

[@ShaneCarles]

Also, have you seen this thread? www.whathifi.com/forum/home-cinema/onkyo-tx-sr705-firmware-update-dts-bomb-fix

[@ShaneCarles]

Look here also. You would download a WAV file and play that sound wav with a SPDIF optical cable from a CD player with optical digital out to update the BOMB glitch issue. You could do that with a PC. - www.avforums.com/threads/onkyo-main-firmware-and-dsp-updates.739501/

[@ezeb]

Thanks for the video, I have a 606 who is experiencing the same issue. Just for my understanding, 600 degrees farenheit right?

[@ShaneCarles]

Yep, that should be fine.

[@ezeb]

Grat thanks, i will try to fix it myself. So process goes like follow right? 1)clean DTS chip with pencil 2) put flux and tilted for flux to go underneath 3)heat chip - ~600F until flux melts in waves of 10 second each 4)let it cool and try 6)apply thermal glue and place heatsink Thanks

[@ohger1]

10:50 LOL!

[@JoJoRockets52]

That explanation about gave me an aneurysm.

[@jbr84tx]

Why not put the heat sink on as soon as it cools down, if the speaker matrix is on and you're getting sound? Why wait? What if the chip overheats again before you put the heat sink on? I saw on another video someone using an infrared thermometer to measure temp, since they didn't have a temp controlled heat gun.

[@VINNY5674]

So it would be better to install these heat sinks when the receiver is brand new to avoid this issue..

[@steveweber7902]

i have a onkyo tx-nr717 no sound i tried the hair dryer method several times it didn't work for me.i will try a heat gun next maybe the chip isn't getting hot enough with the hair dryer.what temperature would you recommend to reflow the chip 300 to 600 degrees ?

[@ShaneCarles]

Try 500 degrees for 1min while evenly moving the heat around the chip. Also, use flux

[@steveweber7902]

shane thanks for the quick response. i am planning on getting a heat gun and some flux and trying your method. i will let you know how i make out.

[@ShaneCarles]

@@steveweber7902 - No problem. Let me know how it goes. Also, check the temp of the chip if you get it going after its been on for a while and see if its getting too hot. It should never get so hot you can leave a finger on it for more than a few seconds. This is the main reason why these chips fail

[@BoricuaIn1707]

Would this solve the issue I have that my 2 front main speakers are not working but my center and surround and sub do work? Could it be that eventually all speakers will lose sound as more contacts come loose from the chip? I have an onkyo tx-nr636

[@ShaneCarles]

If your getting speakers at all then its not the DTS chip. I would be looking at output transistors. Maybe smaller caps around the preamp section.

[@SweatedPear]

Did you ever figure out the problem? My Onkyo HT-R393 just lost the front Left and Right channels. I can get sound out of the Right speaker if I use direct mode.

[@ericjnorman]

Thank you, this worked for me (so far)! My heat gun went only up to 500° but it did the trick. I also added a heat sink based on advice I found elsewhere...I can’t remember if you recommended that. UPDATE: Repair failed after 4 days. Too bad, the unit's otherwise like new but the outlook from other reports isn't very hopeful.

[@kurtwedgwood1766]

Eric, what did you end up doing after the 4 days? I'm about to het mine up, My gun's top heat is 1200. I'm thinking 800 for 10 seconds like another post did. Any new learnings from your experience?

[@ericjnorman]

​@@kurtwedgwood1766 Thanks for asking. I gave up. I also tried a technique found elsewhere (I forgot where) of baking the whole board in the oven for a little bit to reset the connection and that also failed. My engineer friends tell me that microsolder failures are permanent. But it seems to work for some people so what have you got to lose? I wish you much luck.

[@Jayjayuk12345]

Been doing this for over 3 years on these receivers, some of these suffer from the solder issue you address here, however these chips still eventually fail regardless of heat or soldering, this is only a temporary fix i'm afraid may last 6 months or so depending on how much use it gets

[@ShaneCarles]

They usually last after doing this if the chip is heatsinked. I was going to do one on replacing the caps but I lost the shop and all of it's contents in the flood down here in Louisiana. We are rebuilding and I hope to be back at it by the end of the year. The only thing is I lost all of my equipment. I have to replace everything from the ground up.

[@FotomanDave]

Shane, I bought an Onkyo TX-NR555 supposedly refurbished. I got it home and plugged everything in. First thing I got was error "Check SP Mode" and it would shut back down. I took all the cables off and started it again and same thing. I reset it per Onkyo's site. Now it turns on but only in Zone2 mode. I still get no sound. Can you please advise? Thank you

[@ShaneCarles]

Do you get a speaker matrix on the display? The common issue with most of these are the DTS chip on the HDMI board. Check SP Mode means a short across the outputs somewhere. If no speakers are connected then you have an internal short. Could be a capacitor or transistor output shorted.

[@ShaneCarles]

Check SP Mode stands for Check Speaker wiring from what I can read. But if no speaker wiring is connected then that would be an internal short across the outputs somewhere.

[@ShaneCarles]

Check the speaker terminals closely and make sure there are no stray strands of wiring still under the banana screws. All it takes is one jumping across.

[@username_error6969]

what does this repair cost?

[@68pishta68]

Shane, My TX-NR609 has HDMI from front AUX (ROKU) visible on screen, has sound through HDMI to TV (no speaker matrix visible) and can output FM stereo via headphones in DIRECT mode only. Also the Network port will not show link on router AND the USB port does not pass power and does not see 3 firmware files on root of USB stick. Are all these problems related to silly DTS chip? Gonna cook it with a hot air station as soon as my thermocouple arrives. The chips seem to be available ~$20-25 new from China now. Gonna check those caps too. The amp just doesnt seem to kick on without that speaker matrix.

[@ShaneCarles]

Hmmm. Damn. That's some crazy different issues but with no speaker matrix, it sure sounds like the DTS chip. That's all analogue to digital issues from the sound of it

[@ShaneCarles]

But. The USB has me wondering. Take a USB cable you can cut so you can check the red and black wires for 5v there. Let's see if you lost power supply somewhere. Maybe capacitors.

[@ShaneCarles]

Could be 2 issues like I was seeing on this unit where it had 6v on the 5.2v rail. It should be a tad over 5v for voltage sag but not 6v. Capacitors were the issue on that.

[@robertelias8008]

When I TURN MINE ON EVERY DISPLAY COMES ON AND THEN UNIT SHUTS OFF ANY IDEAS?

[@ShaneCarles]

Shorted outputs or caps.

[@RenaissancManEng]

Shane, Thanks for the great video! I have TX-NR828 with the same DTS chip problem. I have the same heat gun as you. I placed the appx 3/8" snoot on the heat gun, and set the temp to 650F and the airflow at about 80%. I heated the chip for what seemed quite a while - I could see the flux pulsing in and out from under the chip. However, the reading I get on my laser thermometer is only about 300F at the chip. IS that hot enough? (seems like it should be). Anyway, I tried this about three times, and I still get no "light". I see the FM section "tuning" but get no output in my headphones. I tried all the THX/DTS settings etc... Any ideas? Thanks!

[@ShaneCarles]

I've had to replace every single one of the capacitors on these boards before to get them working again. If that doesn't fix it then the chip is bad.

[@RenaissancManEng]

Thanks again for the great info! I may just have my local EE friend take a look. I'm just a lowley CS Guy! :-) I'm really pissed at Onkyo right now! I'm considering a future replacement of almost any "non-Onkyo" (or Integra) brand! Maybe Marantz, Pioneer, Yamaha, etc. Do you have any favorites?

[@ShaneCarles]

Lance Bledsoe you are very welcome.

[@ShaneCarles]

I Like Marantz, Yamaha, Pioneer in that order. But there are other more expensive brands out there that are far better than any of those even.

[@tee-jaythestereo-bargainph2120]

I have a pioneer elite sx-n30 and it only works in analog input optical won't work and when I turn on it clicks four times , thanks for the video merry Xmas

[@tee-jaythestereo-bargainph2120]

fixed it ! Had a bad optical connector lol

[@thiagohenp]

Good morning my friend!! I have a HT- R390 with no sound, and when i go to check the firmware version, the display shows "DSP:???????" could give me some help?? thnkss

[@shaunbarnaby1834]

it means the chip is bad - try to reflow it, or you may have to replace it ... i dont know if onkyo still does repairs on them

[@AndreaGiacon]

I have the same model... How did you check the firmware version?

[@patrickschonenberger4216]

Maybe a dump question here, but are we talking about 650° fahrenheit or celsius?

[@ShaneCarles]

Fahrenheit

[@katzenmitgurkenerschrecken7621]

Well....ich have the same reciver and used a hot air station for that task. But it took me at least 5 minutes to get the heat into the chip to really melt the solder. For resolder ich will take out the mainboard und use a heatplate. ;)

[@nagrain]

Hello Shane, I was wondering if I could use a heat gun instead since I don't own a desoldering iron.

[@ShaneCarles]

I don't use an iron on these. I use a heat gun as explained and showed in the video.

[@ShaneCarles]

You can't desolder a matrix chip with a soldering iron anyways. All of the pins are under the chip and are not exposed around the chip.

[@nagrain]

I'm doing everything as shown and still cannot get the audio to come on. What else can it be? I can't get the temperature as high as 650, 400 was my max. Saw another video where the guy only got it into the 200s. Either I fried it or just can't get it hot enough. The hot air gun I bought is supposedly advertised at 650 degrees. Wagner HT400 gun MG Chemicals No clean flux paste

[@ShaneCarles]

Tomz Rain - I've seen the chips be damaged before. Also, the caps on the HDMI board have gone bad before. I just replace all of them to make sure.

[@nagrain]

Sounds like a job I'm not qualified for. I guess I'll have to get it recycled at Best Buy then.

[@nsync233]

what a next ur onkyo receiver? i have like same probelem i was may time reflow Dts chip but still have like same probelm.... plz answer me, what a next check to near Condenser(casipiter)?

[@ShaneCarles]

Or re-ball the DTS chip.

[@nsync233]

thx for ur answers:)

[@ShaneCarles]

No problem. If reflowing the chip doesn't fix the issue, either the chip is defective, you have a firmware issue, a bad FET output, or capacitors. Those are most of the things that would cause the speaker matrix to not show up.

[@adsaudioenthusiastic8704]

HI Sir. I have Onkyo TX-SR875 which have issue of popping and crackling sound from front and surround channels. Few weeks it gave popping sound from Front Left and Surround right speakers. And then the both channel doesnt output any sound, its not completely dead because sometime it give sound with popping noise. When I try to firmware update it stucks in Updating.... option. Please help me to repair my AVR.

[@ShaneCarles]

Popping in the speakers usually points to a bad output transistor but if yours is getting stuck writing firmware, it may have more than one problem. Did your receiver get surged? Sure sounds like it. It may not be worth repairing. But I would start by checking ALL of the output transistors and capacitors. Bad capacitors can also cause popping in the output.

[@adsaudioenthusiastic8704]

@@ShaneCarles Firmware stuck issue solved. But i still dont got sound from digital audio inputs. Avr gives sound only with cd, aux, tape stereo analog input only and give sound in direct or pure audio mode only. No output from other sources and no preamp out. Is it issue of CS3318 audio switch ic?

[@ShaneCarles]

@@adsaudioenthusiastic8704 - So it doesn't output digital audio and only analogue signals? Could be the DTS chip issue.

[@Ashley-kd1vt]

I have a problem with a Marantz sr5005av its sound like you know your stuff so I'm hoping you can help me the unit works an does not have any errors but I can not get any sound out of receiver, I have done factory reset but still no sound. I have tried head phones no sound from them. I don't see any burned place on boards. So I was just wondering what your thoughts would be? I do have schematic for this unit have you had any problems like this with a receiver? Just trying to find someone I can get some idea from. Scene onkyo the same company do you think it could be the same problem. I guess I will check some relays, caps, voltage regs.

[@ShaneCarles]

Is the unit going into protection mode? If not, it still can have an open output transistor that may not trigger the protection circuit. The correct thing to do is start removing the output transistors and checking them for shorts and open until you find the one or multiple bad ones.

[@Ashley-kd1vt]

@@ShaneCarles I get no errors so I will do the out put transistors an see what I get. Thanks for the info

[@Ashley-kd1vt]

Oh an no it is not going in to protection mode thats why I'm trying to just bounce some ideas off someone else. The unit works an does everything it should but just no sound out. So I will use your info an see what happens Thanks again

[@Ashley-kd1vt]

Also Great video 👍

[@pabloosvaldopenizzotto1098]

Did you make a second try to get this unit back to life? Did it work? It is really bad for onkyo brand to know about such a failure in these complex and expensive AVRs!! I would not spend my many in such a device even knowing that onkyo used to be good stuff.

[@sikz26300]

They did a recall, many of the models effected will be repaired for free or if no longer available they will offer a new model at a steep discount.

[@bigsteve20]

What brand flux did you use? Radio shacks are gone in my area. I need to be able to find it online.

[@ShaneCarles]

This is what I'm using. When Radio Shack went out of business I bought 5 containers of this so it would last. It works great and I like it because it's easier to clean off with alcohol. They are out of stock though. - www.radioshack.com/products/rosin-soldering-paste-flux

[@ShaneCarles]

Here's another place that sells it but out of stock also - www.4surpluscity.com/radioshack-6400022-rosin-soldering-flux-paste-non-spill-2-oz-jar.html

[@ShaneCarles]

I would try any Rosin flux and see which one works for you.

[@gatosalamanca]

All have the same problems with the mess...thanks

[@theinfamous4910]

what about an onkyo TX-RS805 that has no sound but the "speaker matrix" is visible?

[@ShaneCarles]

Have you cleared the firmware settings and then flashed with the newest firmware? Other than that bad outputs maybe?

[@theinfamous4910]

little too late...the unit flashed sparks on one of the boards and started smoking. Soooo, dead.

[@NelsonBigGunP200Fan]

ouch. Did one of the amp boards fry? Maybe shorted outputs?

[@davebarnett3795]

thanks for the informative video. looks like a bigger version of my shop. :-P

[@danielmihai300]

Hello, did You fix this receiver, i have a pioneer receiver with the same DTS chip with the same problem, no sound, tried reflow, didn't work, reballd the chip, still no sound, is it possible for the chip to go bad, and a replacement is required? All the voltages are where they should be, accordin to the service manual, don't know what else to do, please advice, thanks!

[@ShaneCarles]

Yes, it is very possible for the chip to go bad and need to be replaced. First thing to check is the 5v rail that supplies power to the DTS chip. It should be no higher than 5.2v DC. If it's at 6v or higher, that would be why it's overheating and burning up. Either fix the 5v regulation or put a heat sink on the chip after replacing it.

[@danielmihai300]

Thanks for the reply, i did check for the voltage supply and its stable at 5.2V, i also replaced all electrolytic cap's, so the only thing that can be bad is the DTS chip, i don't know if you ever tried to update a receiver like this with a bad DTS chip, but on mine when i try to update i get stuck at 20% and then i get "update error 1", tried with 7 or 8 usb memory, and with eachother for 4-5 times, could this chip be the coulprit for the update issue, or is possible to have other bad chips on Digital Main Assy?

[@ShaneCarles]

I would imagine the DTS chip alone would cause update errors if when the firmware tries to update the drivers for the DTS chip itself and if it can't see the chip it gets stuck. I would get a new DTS chip and reflow the new one and then try the updates again.

[@danielmihai300]

Hello again, the new chip arrived, but still no luck, am i doing something wrong, or the problem might be somewhere else, i get the same error when i try to update and no sound, any advice on this case?What else can i try, any ideeas? Thanks

[@walterbrob]

Good informative video. Maybe next time get your parts organized ahead of time.

[@ShaneCarles]

Thank you Walter. I've since completely rebuilt my shop and have things pretty opened up now. Happy New Year to you!

[@jonathanfarias4399]

Thank you for the information I have the same receiver with the same problem and I have the proper equipment cuz I do this type of work but not on a professional level what's the chances this will work for me

[@ShaneCarles]

The chances are good as long as the DTS chip isn't damaged internally.

[@jonathanfarias4399]

Thank you did you ever get the one working in this video

[@ShaneCarles]

Yes. But then I lost it in the flood of 2016.

[@jonathanfarias4399]

Shane Carles I'm sorry to hear that where was this flood sounds like it was bad

[@ShaneCarles]

I appreciate that a lot...Thanks. It was bad. We lost everything we owned, including our cars. Had to rebuild my house from the floor up to the ceiling. It was the flood of 2016 in Louisiana. It was a 1000 year flood. I had over 4ft of water that came into my house. A lot of people's homes were over the rooftops though.

[@dougdoug7657]

What kind of flux did he use?

[@ShaneCarles]

I use rosin flux I got from Radio Shack a while back. But a flux pen will work also

[@profewiase]

Hello, I have watch your video and follow it like you said, but while I was reflowing the chip, I heard a crack sound and later on, I found out that there are some bubbles coming out of a small place between the black insulator and chipset board. After viewing with magnifier, I saw a little crack between the insulator and the chipset board. That's if mean the dts chip is damaged? But the sound work when zone 2 or the Bd\Dvd + power feature is used to ignore the hdmi board. If the chipset is damaged, where can I get replacement part because am in Ghana/Africa and there is no onkyo service here, so I have to fix this myself. Thanks a lot

[@ShaneCarles]

You may have used too much heat for too long.

[@profewiase]

Shane Carles not that long, only for few seconds. So does it means the chipset is damaged?

[@ShaneCarles]

Probably so. If it cracked the lower layer of the matrix circuit, it could break the pin layer connections.

[@bassinbillRC5300]

My friend you need a brother P-touch model PT-1280 label maker. Made my life much easier identifying everything in my supply drawers and cupboards.

[@seanbittner7136]

Great video, I ordered a rework station and it's first job will be my TX-NR636. I'm going to follow exactly what you do. My unit has two of those infernal chips. Hmmmm..... The most aggravating issue it has is the video blinking out till the unit is off for 20 mins but sometimes the sound gives me grief till I do the same. Is there a chip for each?

[@ShaneCarles]

I don't think there is a DTS chip for the video side, it's just used for converting audio from analogue to digital and vise versa. It would be where the SPDIF goes and when it has an issue like overheating and desoldering from the board by cracking the solder joints when it flexes from the heat then cooling over & over, you lose the audio matrix grid on the display and the amplifier relay never clicks to fire up the amp. This is the most common issue that happens. Also HDMI doesn't switch in some cases.

[@ShaneCarles]

And thank you. The camera I was using is a great camera, but I was trying out settings on it when I made this video and I did finally get it smoothed out. The strange thing though, it plays and looks good when played local. KZbin did something to it when I uploaded it. I didn't use any modifications either.

[@ShaneCarles]

For sure on the rework station. That will let you upgrade this chip to one that doesn't have the issue. Look into the part numbers on your chip and see if there is a package update that matches the grid type of the original. They have updated these DTS chips for most of the HDMI boards.

[@seanbittner7136]

:-) After about a year the video would drop off after a while. Fast forward a year and now I get about 5 minutes of video. What's an SPDIF? I was messing with it a couple hours earlier and touched one of those chips to see how hot (it wasn't hot) and the video dropped. I don't know what to do, I don't want to buy another amp and should not have to and Onkyo is in denial. Any suggestions?

[@ShaneCarles]

SPDIF is the square ports on the back of your receiver. Those are for optical SPDIF digital audio and they also have the single orange RCA jack for coax SPDIF Digital Audio in. Lets say you have a desktop PC and it has SPDIF Optical out on the back panel. You would take a toslink optical cable and connect that optical out to one of the optical ins on the receiver. You go to the video input settings and change the audio to SPDIF Audio 1 (Most Onkyo receivers have 2 of these...1 & 2) or something like that. That would then give you the digital audio tracks of movies in DTS surround sound or whichever surround sound coding was used, it switches it for you and you hear a relay click when its working. The sound range is instantly changed to a much higher sound quality and the channel separation is unreal. I can do a video on a newer Onkyo Receiver I have here that's very much like the way its done on all of them and show you where those settings are. Any audio device that you aren't using HDMI for would use this since the video output may be something other than HDMI. HDMI passes digital audio over the cable but I think on a computer audio setup, even if the computer has HDMI, it sounds better with the SPDIF Optical doing audio because the chipset would be Realtek and the HDMI video out would be Intel, Nvidia or ATI...something like that. The audio drivers for those are simple & not very great in some cases.

[@eliglbe]

I love that mess

[@ShaneCarles]
