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 love this receiver to death and only wish Onkyo would have cooled the chips properly. Will keep you guys updated. Catus Maximus thank you so much for sharing this video it really helped...
@@hannycurak3259 Unfortunately No, after about 3 months it started acting up again. 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...
@@gorpri1 Yes I did the same on my new Nr 6050. I migrated the two 140mm fans in a pull configuration. I have them outside right over the HDMI board and hoping for the best.
The connector that you mentioned having trouble with is a compression connector. Push & hold down on the thicker side of the connector to remove and insert the wire ribbon easily.
Perfect. My personal experience is to heat the dsp chip for approximately 1:20 min at 260 degree Celsius. I used a reflow station for approx 40 Euros. Worked fine for me and I did repair two receivers successfully. Afterwards I put a passively aluminum cooler on to the chip!
Thanks for posting this. My Tx-nr809 lost audio a few weeks ago suddenly. I found your video and used a heat gun to apply some heat, let it cool and turned it on. Boom.. The speaker relay kicked on! I haven't hooked it back up yet and I'm know this I'd probably just a temporary fix but maybe it will give me a little more service before it totally dies. Fwiw my unit said it had just over 17k hours of use.
UPDATE *** Worked only for 2 weeks, tried to repair again but issue keeps coming back. Giving up, and getting another receiver, this time NOT Onkyo*** great video, used a heat gun with nozzle to heat the dsp chip for 1 ½ min. and now sound is working, also the Network actually also work it was not responding before repair. Have added a small heat sink on top of dsp to improve, but thank you very much.
Mine just went out this month (Jan 2021), and I managed to reflow the DTS and get it working. Video Out just stopped working. I'll try one more thing but I think it's time for an upgrade. Fortunately it's lasted this long from what I'm reading.
What if the board that the chip is on is installed vertically? I won’t/can’t take out the entire board in case this fix doesn’t work for me, too much trouble. Is it still worth blowing hot air on the chip even though it would hitting it from the side in addition to other components?
Hi. I have a question. Firstly thanks for the videos. I know this is an old one but I have a problem with my much loved, 20 year old Onkyo TX-NR905. I had audio but no video which seemed like an HDMI board fault. I replaced the HDMI board but now have no video or audio. Wondering if you have any ideas?
Very instructive, very useful learning!... I know this receiver IS old and entry level, but i have two identical VSX-522 units here at home (probably the canadian version of vsx-521) , one upstairs and one downstairs. The one in the living room stopped working this week (all seems ok with controls and functions, but NO audio at all coming from any speaker outputs, or headphone jack)) i tried everything to give it a factory reset (power/standby + "BAND" button), and it does not work at all. The video monitor out is working so i was able to go in MCACC mode, to be able to manually generate the calibrating tones for the individual amped channels, nothing outputs to the speaker when i push it. Only sound that comes out of there, is a thump from the SUB on power-up, which makes sense since it has it's own amp. (and maybe a grin or two coming from my mouth) I should mention, ALL HDMI inputs are functional and audio reaches the TV in HDMI=THRU mode. So i decided to bring the other unit to the bench ...: EXACT SAME RESULT So now i have TWO vsx-522 stacked, which for now , only LOOK good. Do you think these vsx units could have the same DTS dolby chip problem? Thanks for doing what you do !
The problem is, with all this "repair", you just temporary fix the problem. From my understanding, most often not the solder balls on the bottom of the chip are the problem, but the stuff contacting actually the die with this green substrate plate, which is *inside* the chip. Louis Rossmann did a good video about this I would recommend to understand the real problem. With heating it up to some amount, things might get a little bit realigned inside the chip - but only temporary. So the only real permanent fix would be to get a replacement chip (but they are not available for that "old" receivers). The root cause of the problem is the thermal stress applied to the chip because of insufficient / no cooling (not even a heatsink). Same happened to graphic chips (most often nVidia) in notebooks due to same reason. Broken by design.
I think you're right. even a small amount of heat will allow mine to function again but as soon as it is switched off and cools again, it doesn't function when switched on again
yeah the root-cause is definitely a thermal stress. I don't understand why are almost all receivers passively cooled. I just added a really thin and quiet active usb cooling fan to the bottom of my yamaha. The heat cumulates over time so even a little breeze can keep it running superbly for years as there is never enough stress on the transistors etc. Before when used at near max volume it would turn off almost instantly, now it can run minutes before turning off at max volume (of course that's too much it can almost destroy your hearing and damage speakers). Before it was under normal operation running very hot (like 70°C), now it's warm (I'd say max 45°C). Btw I don't have it in an enclosure just sitting on top of my desk. So yeah definitely put some passive radiators on those chips or maybe even active cooling.
So heating and putting a heatsink on top should fix it for a few years? I have a high end version (got it for free) and everything works except for the issue in this video....
Yep. MANY laptop graphics cards have died the same death, and heating the chip only ever works temporarily. Eventually, the time it will work between needing to be reheated again gets smaller and smaller til the point where heating just doesn't work at all anymore.
I have an ONKYO TX NR626, that one day it start to send to the LEFT Speaker , what I believe "bad current" and start clipping, so I disconnected it. At the present time I Had Only connected Left, Right, and Center speakers. So now, I am only using Right and Center. Any suggestions what to look for? What seems to be the fault? Thank you in advance.
I have 2 NR 609’s that have each been repaired by only for this problem. After getting them back they worked for about a year. Neither one plays audio again. I took them apart and heated them both up to attempt resolder and then installed heat sinks. They both worked for about a week. One has 9000 hrs and the other 10k. It’s crazy when I have a 30 year old Denon that still pounds after years of abuse.
It's the shitty BGA designed chips that have this issue. It's a crap design to have solder balls UNDER the chip. The boards warp/cup under those chips from heat, and it pulls on and makes the solder joints go cold under there.
Thx for this Video. I just used my hairdryer on high temperature und low speed for about one minute on the Chip and after this, the Reciver works like before.
Thanx for the video but my issue is different. Speakers icons are on but no sound. Sometimes I have to leave the receiver on and after a while the sound will kick in. Recently it has gone gone without a sound even if i leave it on for hours. What could be the problem?
Hi my onkyo receiver started to have a delay issue with sound kicking after about 30 seconds or more when the receiver and my tv is on. And is dependent how long the receiver stayed off. Do you think it could be related to that chip? Thanks
Im have the same problem aswell the amp turn on fine hdmi display the blue screen when and there is no sound on speakers planning to heat the chip like you did. Did you manage to put the heat sink. My board numbers is BCHDM-0471 if someone has a working one please hit me up
bonjour j ai le même diagnostic de la par d'un réparateur carte mère hs à cause de la puce dts non réparable en plus sur un TX NR 5007 j'essaierai bien cette méthode ?est ce sans danger pour les composant autour merci d avance
Another thing to try is to look for any 100uf 4V metal can caps and change those, ideally for a higher voltage rating and possibly even with a slightly higher value since the higher the voltage of the caps the more the internal series resistance is but the higher the value of the cap the lower the internal series resistance is so if your upping the voltage rating it might be an idea to up the value a bit to compensate for any lowered esr from higer value voltage. This advice is not set in stone but i did see somewhere that someone replaced the 100uf metal can caps with a much higher value and it still worked.
I have a huge problem on my onkyo receiver. I am using the aux input with my phone and whenever I turn on the receiver, there's only one click and theres no sound coming out of the speaker. It could be an easy fix but I haven't found anything in the internet yet. please help.
I have a model 707 that has the same issue. I used a heat gun and heated the chip up 5 times but I had no luck getting the speaker grid to come back on and audio back to working. The funny thing is I hear 3 relays click on as soon as I press the power button but no click from a delay relay like a normal receiver. All the audio driver transistors are getting hot but the final transistors that are mounted to the heatsink are not. Any suggestions on what else could be wrong with this receiver will be greatly appreciated. Thank You!
How long did Onkyo have this problem? What years, what models? I do have a TX SR 707 it is in my garage and last summer it would cut out until I put a heat sink on that dts chip, how ever since it is winter it will not start until I let it warm up for ten minutes or so. My older Onkyo 901 amps have been with me for 30 years no problem. I think that I do still like Onkyo but If I buy another one which ones and what years were bad? Or should I just go old school. Peavey is me ve... theater or rock and roll amps?.. do not need all of the bells and whistles. How ever since my computer or my TV is normally my source signal HDMI would be nice. Right now I am splitting my 1/8" jack from my sound card to the 707and two Onkyo 901's and three DefTech 15" powered subs I have 12 speakers and I can make it Thump, having lived and worked for a sound company in Nashville for years I do like to feel the base now and then. My long throw 12" boxes that I built are 4 ohm loads and my sony 901"s are on top so get a nice and full sound. I just find that when the 707 is maxed out it is only about a third of what every thing else will do and I really like to keep unity gain on all units or else there is no gas peddle if you want to push it. Do you have any recommendations for the future of my home entertainment system? Peace, Jim
Cool project. I found thick chunks of aluminum on the chips in my defunct flat screen tv when i took it apart that would make good heatsinks. I have a 1st gen digital Realistic reciever (1984!) that has small issues. I may open it up and look for the obvious. I couldn't guess how many hours it was played.
Any updates? Did you install heatsinks? I need to repair HDMI Main out. Im using big and heavy HDMI plugs so it has done something with the small pins. Cable and plug needs to be in a special way to get video output. Might need resolder. And a good old dust remove inside. Might also look at the fans. Havent heard them or the realy turning on lately
i tried the hair dryer method on the dts chip on my onkyo tx-nr717 that didn't work for me. i saw on other videos on you tube others used a hair dryer and after a few attempts the speaker matrix popped back up. i tried at least a dozen times did not work. i am thinking a heat gun may work or there is another issue. could be a power issue. any suggestions ?
I tried to do a reflow on my integra dtr 40.2, put some flux around the chip and heated it up with a heat gun. After a month i had to heat it again, i put a heatsink on the chip and it still failes periodically every month or so. For a year i've been heating the chip every time audio goes out, not exactly an elegant solution but it hasn't kicked the bucket yet. Also i had an issue with a back channel speaker that would only play static, out of pure curiosity, i put heatsinks on my entire hdmi board, and it fixed that problem
@@Truth-Machine5000 Haha, nope! I retired my amp, i couldn't get it to function anymore. I must have overheated the chip because i can't get any sound out of it.
Yes, almost certainly. But you'd have to remove the board from the receiver and squirt flux under the chip, heat it to reflow the solder, then clean with flux removal spray. If there are any high impedance pins, any remaining flux will create leakage paths. And in the industry, we use degrees Celcius, not fahrenheit. Lead free solder melts at 217C. Measuring the top of the package is fine, just know that the solder balls underneath will be at a lower temp, so heating the top to 260C is best. That's the max temp for virtually all chips when subjected to a solder reflow process. Without flux, heating it up is ok but I don't think it'll last long. If he had some cold spray, you'd likely see the problem return.
Wow Maximus! You know your stuff! I have an HT-R990. I plugged in a composite video jack into a normal video input and the unit went into protect mode. Got it to restart again but the speaker grid lights stay on and no second click of speaker relay. Did volume up down and factory reset. No sound. What do you think? I opened the unit. 2 fuses blown to the speaker relays. I replaced them. AVR goes on off. I shut it down. Ideas?
hi, I tried everything to reproduce Dolby 5.1 on my Onkyo TXSR494, nothing to do, I can reproduce DTS and DTS-HDMA perfectly but I can't hear anything in Dolby 5.1 or Dolby Atmos. Could it be this chip's fault or should both formats have problems? thanks good work
I have an Onkyo TX-NR609 that does not power on. I unplugged it for 20 minutes and when I plug it in again it just keeps clicking every 3 seconds or so. There are no lights coming on when it clicks. Any ideas on where I can start looking for a problem? I have already checked the fuses and the big transformer has primary and secondary voltage for a brief second between clicks.
That's more complicated it sounds like it's starting up and at some point it's determining there's some kind of issue and then shuts down and cycles. look online for the factory reset button combination and try that
As far as I know, silicon image had designed chips to process the hdmi signals. I have a denon and marantz receivers that use various versions. The denon receiver had an sil9185 chip that failed, shorted the supply. Just removed the chip and ordered another one from China. Fingers crossed. I don't think TI builds a direct replacement part for silicon image, at least not for receivers 8 yrs or older.
Iv got the speaker grid indication but no audio out the speaker or pre amp outs i didn't try this yet but what do you think it could be the issue? I wanna use it as a pre amp for my Emerald physics 100.2se amp
I have an Onkyo TX-SR313 which is doing the same thing, will try this for sure. I have an SMT reflow oven at work and my job was multi-layer PCB design, so I should be able to lick this. Loved the sound my amp had... don't want to go through a whole repurchasing thing...
If you not put an hetasink on the chip an maybe an cooler to this area like you said, the failure will come back soon, cause the area will be very hot if the Receiver is in use, and before heating the chip up use flux and cover the chips around with kapton or aluminium band, and circle around with the heat gun not pointed cause overheating a spot. ! Gratulation that you could give yor receiver a scond life !
I've got a txnr709 and the chip seem bad works when I heat it up to 350° but after it cools down and I turn it off it doesn't come back on. Do they sell new or refurbished boards ?
I have a receiver for this 875, silver. From time to time he has a radio-like hiss when he's tuning in to the station. It always occurs in the right front channel of the tower. This hiss does not last long, it stays for a while and then disappears. Sometimes it comes back. Could you give me a glimpse of the problem? I have already tried the ground loop, removing the ground plug from the outlet. Impedance has also been noted. I'm from Brazil, here nobody was able to help me. I thank you already friend.
It help a lot for us Sir. Sir, do you have spare Spare DSP board for Onkyo TX-SR501. Problem dont have output and i found out a open coil and short AK4586 Chip.. Can you pls help if you know where can i buy the board or supplier. Thanks alot
Thank you very much. I used some hint in the comments and applied 230C for approx. 1 minute. I bought this Receiver for 170€ (used condition) and the issue with the DTS chip just appeared after the warrenty of the reseller ran out. I just applied your fix and now I am running some tests (and if everything works, I will install some additional heatsinks later). I will keep you updated, if everything works out in the future.
Some of these comments, lol. This was a wide spread issue across many manufacturers during some specific production years due to them all using the same garbage TI DSP chip. So before you "stick with" your brand of choice, keep in mind that Onkyo, Denon, Yamaha, Pioneer, etc. were all effected. Just like how they were also all effected by the janky ass HDMI 2.1 ports on the 2020 models.
Onkyo doesn't sell parts for this anymore all they do now is allow you to register the serial number of a defunct receiver of the this era and they'll give you a 30% off a new unit
Hi, nice video, need help here, i have a onkyo TX NR 656 7.2 receiver , i have no display on the TV, both my main and Sub HDMI ports arent displaying picture , i have sound and the buttons work. Reset didnt work .pls help !!!
Hi Great vid, thanks I've tried this now a couple of times and last attempt I reached 330F. couple of questions - Is this know to be a proper fix, even for a year or two? I ask, as mine is still not working when it cools - What sort of temperature can we expect the chip to fail at? I’m using a paint stripping thermal gun…lol
I found that I just got lucky ( Issues have come back I now have to switch inputs around to get the speakers to work) sometimes you have to heat it up much hotter hot enough to get the soldier to melt, also Flux should be used. Also I have since learned that some of these issues are due to the microscopic wires inside the chip itself failing.
@@CatusMaximus Hi and thanks for the reply. I’m thinking the processor has had it, and on top of that I may now have blown part of the amplifier circuit, as it requires high volume now to get a decent sound level. Had a look online and cannot locate replacement board for this, so I fear it’s time for a replacement unit. Quite shocked and disappointed at just how bad this thing has lasted, and the level of support for it. I don’t think I’ll be buying Onkyo again, even though it appears the TI chip is the culprit
@@CatusMaximus Hi Just to let you know, I heated a couple more times using flux. Just ordinary flux from my soldering kit, using a brush to apply. I think temperature must have been approaching 400F easily, and am surprised the board didn’t fail. I also did a factory reset, as at one point the sound appeared muted. Seems to be working properly again now for the past week, so fingers crossed. Appreciate the help….you may well have saved me £600….cheers
I'm from Brazil and I have an Onkyo TX-NR 686 and the HDMI output (main) doesn't work anymore. The rest everything works. Can you tell me if Onkyo sells boards or do I have to have it repaired. I bought this receveir in the United States. Could you help me by sending me addresses.
sir, please help me, why is my amplifier like that, the brand is ONKYO, the AUX IN AND Fm radio don't work, it doesn't work, but when it's in the USB PORT, it's ok, it works, it's just that it doesn't take long to play the music, it dies a bit, it also dies when it takes too long Is it possible that my amplifier is an issue because the model is " ONKYO TX-SR313 ☹️☹️
Catus Maximus how long has it ran since you fixed it? Just got a Onkyo with the same DTS chip issue and I’m wondering if it’s worth the trouble to go through your process.I only spent $15 for it so it’s not a big deal but it is a really nice receiver
I think we are on the same boat. I have a DTR 6.8 with issues with anything Dolby digital i.e. Dolby 2.0 surround, DD 5.1, EX, TrueHD etc, I'm at wits end on what to do, but hopefully there's a solution out there.
During the very early days of Sirius Satellite Radio before they merged with XM they sold head units for around $300 that had a lifetime subscription that was tied to the specific serial number of the head unit. that ended after they merged with XM so it's only the really old units that even have the possibility so just hunt down old Sirius satellite radios. It was a consumer contract when they sold those lifetime subscriptions so that's why they were never canceled it is also my understanding that they are not valid for online stream. It's easy to know if you found one of those special units you just simply turn it on and let it do its Channel updates and you either have 150 channels or you have no Channels.
That's why I still keep my old Yamaha RX-V2400 & HTR-5890 THX 7.1 Receivers... They still work great and are nearly 20 years old. They don't have HDMI or support master audio but have better equalization from the microphone auto setup then this Onkyo.
Sir I see this video and I use Yamaha rxv665 avr and my avr display in suddenly decoder mode off but last time same issue display but automatically start speaker icon and on but today is a same problem see plz what is solution plz send me
Thanks for the tip, in case the thermal blower has to reach a temperature of 200 degrees? and for about 15 seconds on top of the chip? after that repair did you have a problem again?
@@achibbbb I cleaned the whole ONKYO with the Contact Cleaner spray thoroughly. Then placed a heat sink on the DTS Chip and it's been working perfectly since then.
Next time when you want to disconnect the black cable just push it down.. And you can easely disconnect the cable without ripping it to peaces.. Nice video tho.. Love to watch it..
Hi, Thank you for your Video! I just fixed my Integra pre-amp by doing exactly what you did here. I was going to try the "baking" method until I stumbled across your vid. I did use the infrared thermometer, and it took a while to get the chip to get to temp. My first try failed, and the speaker indicator lights did not appear. I don't think I got the chip over 300deg f because I was being cautious. I tried again, and this time I let the chip get to 306deg f. I kept it on that temp for about 10 seconds. This worked!! I know nothing about electronics, at ALL, but It didn't look hard, so I figured I have nothing to lose. That being said, can you do a follow up vid to show what other chips might need the heat sinks, before I close it up? I'M not sure which ones are chips and which ones aren't.. that's how little I know. Lol. I got a heat sink kit off Amazon, and it came with a bunch of them. Thanks again for your wonderful vid!! You just saved me a couple hundred dollars minimum!!!!!!!!!
Hi, I heated chip to 185 C and sound come back. Now I have mounted heatsink to help cooling. Soon I will post video with all details on my channel I have recorder all procedure. Thanks :).
I also bought two with the exact same problems. Why didn't you use any flux? Also, are you going to mount some radiators over the DSP chip? LE.: also, 115F (46C) isn't really too hot for that CPU especially since it's a fine pitch IC and not a BGA.
I need the update this video it turns out much of this issue has to do with the solder joints internal to the processor package and not the BGA grid to the motherboard. I've already switched back to my old reliable Yamaha because my imputs already started becoming intermittent and I have to switch between inputs before sound will come out
I can't thank you enough for the break down and info you shared in this video. I've never commented on any video before, but I truly am grateful. I have a onkyo txsr601 and it runs the music in my shop, hopefully you saved it from a load of buckshot. I'm gonna head to HF now and buy a pen heat gun, and try it. Can I take heat sinks out of other stuff, cut em down and use them, or do they need to be specific sizes?
Know anything will work as a heat sink just make sure it's not too big and won't touch the other circuits around the chip and find some way to attach it
Look at some of the other comments some people have mentioned that using electrical contact cleaner as help too. Also with the heat gun you can make sure this is the issue just by heating it up to around 150 degrees and see if it makes a difference
I didn't try the 150 deg. I got it to 300-330 deg. ....I could smell hot solder, so I stopped and let it go back down to about 80 or so. And still have no speaker display. That was a couple hours ago, I just added some petroleum based flux, and did the same thing, its cooling now, I'll clean it off and see what happens.
You may have to try again at 375 to 400 that's the temperature of the ovens run at when they make these boards so even 330 might not quite be enough to properly melt it even if you do smell some flux. The scale and breadth of this issue with Onkyo really has turn me off and the sad thing is is many Integra receivers also suffer from this issue. my fifteen-year-old Yamaha keeps Trucking along.
Hi to all. Did you ever replaced dsp chip? I have replaced it on my yamaha rxv773, and i bought updated version DPTP4. Inside was CPTP4. Now I have speaker icons, but no sound at all. Not even a test tone.
This is true. We need to consume more and more in order for these fat bastard companies to pay big dividends and huge bonuses. They know exactly how long something should last. Think about it. How come some old electronics seem like they are going to run forever? And in this day and age, they haven’t figured out to make solder as good at least as it was with lead?
just to provide a data point, my unit failed right around maybe 2000 hours. (i bought in 2012, and have it RAM in 2016, and today is 2020). i just check my total usage to this very day is just under 4000 hours, so it is very possible at the time of RMA it has less than 2000 hours. so i think this may be less depend on actual hours, and more on the age of the receiver. 4 or 5 years maybe a good time for the problem to surface. still quite impressed that Onkyo picked up the bill for it. the round trip shipping of a 50 lb receiver probably cost a small fortune.
I never had a model like the one in this vid tore apart yet... Are those yellow bias pots on the tops of the amplifier boards right by the heatsink there? How convienient if they are. Crank em up! 😬
Thanks for the video and tip! How many °C should it be heated to? How many minutes should it be at this temperature? It is necessary to heat shock several times in a row?
Awesome video, it helped me to understand issues that I may be able to fix on other types of electronics. Have to ask, did it work after you reheated it?
OK your 2nd attempt was closer. But 350F won't do it either. I'd love to know just what is so therapeutic about heating that chip well below the melting temp of the lead-free solder required when that unit was made in that 2009+ era. Also, a chip temp of 120-ish is not all that hot. Probably does not need a heatsink.

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 love this receiver to death and only wish Onkyo would have cooled the chips properly. Will keep you guys updated.
Catus Maximus thank you so much for sharing this video it really helped...
still working?
@@hannycurak3259 Unfortunately No, after about 3 months it started acting up again. 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...

Perfect. My personal experience is to heat the dsp chip for approximately 1:20 min at 260 degree Celsius. I used a reflow station for approx 40 Euros. Worked fine for me and I did repair two receivers successfully. Afterwards I put a passively aluminum cooler on to the chip!
Forza Guy i think for Onkyo stuff it is always good to put a aluminum cooler onto the dsp Chip. Then you probably will not run into problems!
is it still working please?

Thanks for posting this. My Tx-nr809 lost audio a few weeks ago suddenly. I found your video and used a heat gun to apply some heat, let it cool and turned it on. Boom.. The speaker relay kicked on! I haven't hooked it back up yet and I'm know this I'd probably just a temporary fix but maybe it will give me a little more service before it totally dies. Fwiw my unit said it had just over 17k hours of use.
Bro teac 8800 av receiver only front lift right chanels not sound bro centre back sorrounding is good work but problem??? Plzz reply
UPDATE *** Worked only for 2 weeks, tried to repair again but issue keeps coming back. Giving up, and getting another receiver, this time NOT Onkyo*** great video, used a heat gun with nozzle to heat the dsp chip for 1 ½ min. and now sound is working, also the Network actually also work it was not responding before repair. Have added a small heat sink on top of dsp to improve, but thank you very much.
Having the same issue so I'll work on the fix but before I do I'll need to get some parts like a hearsink. What size heatsink did you use? Thank you.
Thank you so much for your help. This corrected my issue and I couldn’t be happier!! You are my hero 🤘🏻
Glad I could help!
Mine just went out this month (Jan 2021), and I managed to reflow the DTS and get it working. Video Out just stopped working. I'll try one more thing but I think it's time for an upgrade. Fortunately it's lasted this long from what I'm reading.
What if the board that the chip is on is installed vertically? I won’t/can’t take out the entire board in case this fix doesn’t work for me, too much trouble. Is it still worth blowing hot air on the chip even though it would hitting it from the side in addition to other components?
Hi. I have a question. Firstly thanks for the videos. I know this is an old one but I have a problem with my much loved, 20 year old Onkyo TX-NR905. I had audio but no video which seemed like an HDMI board fault. I replaced the HDMI board but now have no video or audio. Wondering if you have any ideas?
Very instructive, very useful learning!...
I know this receiver IS old and entry level, but i have two identical VSX-522 units here at home (probably the canadian version of vsx-521) ,
one upstairs and one downstairs.
The one in the living room stopped working this week (all seems ok with controls and functions, but NO audio at all coming from any speaker outputs, or headphone jack))
i tried everything to give it a factory reset (power/standby + "BAND" button), and it does not work at all.
The video monitor out is working so i was able to go in MCACC mode, to be able to manually generate the calibrating tones for the individual amped channels, nothing outputs to the speaker when i push it.
Only sound that comes out of there, is a thump from the SUB on power-up, which makes sense since it has it's own amp. (and maybe a grin or two coming from my mouth)
I should mention, ALL HDMI inputs are functional and audio reaches the TV in HDMI=THRU mode.
So i decided to bring the other unit to the bench ...: EXACT SAME RESULT
So now i have TWO vsx-522 stacked, which for now , only LOOK good.
Do you think these vsx units could have the same DTS dolby chip problem?
Thanks for doing what you do !
The problem is, with all this "repair", you just temporary fix the problem. From my understanding, most often not the solder balls on the bottom of the chip are the problem, but the stuff contacting actually the die with this green substrate plate, which is *inside* the chip. Louis Rossmann did a good video about this I would recommend to understand the real problem. With heating it up to some amount, things might get a little bit realigned inside the chip - but only temporary. So the only real permanent fix would be to get a replacement chip (but they are not available for that "old" receivers). The root cause of the problem is the thermal stress applied to the chip because of insufficient / no cooling (not even a heatsink). Same happened to graphic chips (most often nVidia) in notebooks due to same reason. Broken by design.
I think you're right. even a small amount of heat will allow mine to function again but as soon as it is switched off and cools again, it doesn't function when switched on again
yeah the root-cause is definitely a thermal stress. I don't understand why are almost all receivers passively cooled. I just added a really thin and quiet active usb cooling fan to the bottom of my yamaha. The heat cumulates over time so even a little breeze can keep it running superbly for years as there is never enough stress on the transistors etc. Before when used at near max volume it would turn off almost instantly, now it can run minutes before turning off at max volume (of course that's too much it can almost destroy your hearing and damage speakers). Before it was under normal operation running very hot (like 70°C), now it's warm (I'd say max 45°C). Btw I don't have it in an enclosure just sitting on top of my desk. So yeah definitely put some passive radiators on those chips or maybe even active cooling.
So heating and putting a heatsink on top should fix it for a few years? I have a high end version (got it for free) and everything works except for the issue in this video....
@@peterdevreter did you fix it?
Yep. MANY laptop graphics cards have died the same death, and heating the chip only ever works temporarily. Eventually, the time it will work between needing to be reheated again gets smaller and smaller til the point where heating just doesn't work at all anymore.
I have an ONKYO TX NR626, that one day it start to send to the LEFT Speaker , what I believe "bad current" and start clipping, so I disconnected it.
At the present time I Had Only connected Left, Right, and Center speakers. So now, I am only using Right and Center. Any suggestions what to look for? What seems to be the fault? Thank you in advance.
I have 2 NR 609’s that have each been repaired by only for this problem. After getting them back they worked for about a year. Neither one plays audio again. I took them apart and heated them both up to attempt resolder and then installed heat sinks. They both worked for about a week. One has 9000 hrs and the other 10k. It’s crazy when I have a 30 year old Denon that still pounds after years of abuse.
one question please: did you use flux when you resoldered it?
30 year old receivers didn't have hdmi circuit boards to go bad. I have 30+ yr. old Onkyo's still going strong.
It's the shitty BGA designed chips that have this issue. It's a crap design to have solder balls UNDER the chip. The boards warp/cup under those chips from heat, and it pulls on and makes the solder joints go cold under there.
@@vortexor1 yes
and is it still working? wish you a merry Christmas
Where did you get the heat gun and which model? Thanks!
Thx for this Video. I just used my hairdryer on high temperature und low speed for about one minute on the Chip and after this, the Reciver works like before.
Glad it helped
Where are spares and repares done from in kenya??
Thanx for the video but my issue is different. Speakers icons are on but no sound. Sometimes I have to leave the receiver on and after a while the sound will kick in. Recently it has gone gone without a sound even if i leave it on for hours. What could be the problem?
Could be just another Manifestation of the same root cause. I Ended up getting a yamaha receiver and it's been great
Not of my channels are working and I get static could it be that chip . All I ever owned was vintage receivers and never had any problems
Hi my onkyo receiver started to have a delay issue with sound kicking after about 30 seconds or more when the receiver and my tv is on. And is dependent how long the receiver stayed off. Do you think it could be related to that chip? Thanks
Im have the same problem aswell the amp turn on fine hdmi display the blue screen when and there is no sound on speakers planning to heat the chip like you did. Did you manage to put the heat sink. My board numbers is BCHDM-0471 if someone has a working one please hit me up
bonjour j ai le même diagnostic de la par d'un réparateur carte mère hs à cause de la puce dts non réparable en plus sur un TX NR 5007
j'essaierai bien cette méthode ?est ce sans danger pour les composant autour merci d avance
Another thing to try is to look for any 100uf 4V metal can caps and change those, ideally for a higher voltage rating and possibly even with a slightly higher value since the higher the voltage of the caps the more the internal series resistance is but the higher the value of the cap the lower the internal series resistance is so if your upping the voltage rating it might be an idea to up the value a bit to compensate for any lowered esr from higer value voltage. This advice is not set in stone but i did see somewhere that someone replaced the 100uf metal can caps with a much higher value and it still worked.
It's 99% not a cap issue, but a BGA chip solder issue.
I have a huge problem on my onkyo receiver. I am using the aux input with my phone and whenever I turn on the receiver, there's only one click and theres no sound coming out of the speaker. It could be an easy fix but I haven't found anything in the internet yet. please help.
Thank you for sharing your ideas.
Is it possible to buy the DTS chip for TX-SR309.
Not worth the effort I would get a Yamaha receiver
I have a model 707 that has the same issue. I used a heat gun and heated the chip up 5 times but I had no luck getting the speaker grid to come back on and audio back to working. The funny thing is I hear 3 relays click on as soon as I press the power button but no click from a delay relay like a normal receiver. All the audio driver transistors are getting hot but the final transistors that are mounted to the heatsink are not. Any suggestions on what else could be wrong with this receiver will be greatly appreciated. Thank You!
Help 😥
What would cause a popping/crackling / tickkkkk sound in one of my stereo speakers?
I'm using #Yamaha rxv 1900
How long did Onkyo have this problem? What years, what models? I do have a TX SR 707 it is in my garage and last summer it would cut out until I put a heat sink on that dts chip, how ever since it is winter it will not start until I let it warm up for ten minutes or so. My older Onkyo 901 amps have been with me for 30 years no problem. I think that I do still like Onkyo but If I buy another one which ones and what years were bad? Or should I just go old school. Peavey is me ve... theater or rock and roll amps?.. do not need all of the bells and whistles. How ever since my computer or my TV is normally my source signal HDMI would be nice. Right now I am splitting my 1/8" jack from my sound card to the 707and two Onkyo 901's and three DefTech 15" powered subs I have 12 speakers and I can make it Thump, having lived and worked for a sound company in Nashville for years I do like to feel the base now and then. My long throw 12" boxes that I built are 4 ohm loads and my sony 901"s are on top so get a nice and full sound. I just find that when the 707 is maxed out it is only about a third of what every thing else will do and I really like to keep unity gain on all units or else there is no gas peddle if you want to push it. Do you have any recommendations for the future of my home entertainment system? Peace, Jim
I got mine for 1.99 and it turns on then right back off after 2-3 seconds, how do I fix that ?
Cool project. I found thick chunks of aluminum on the chips in my defunct flat screen tv when i took it apart that would make good heatsinks. I have a 1st gen digital Realistic reciever (1984!) that has small issues. I may open it up and look for the obvious. I couldn't guess how many hours it was played.
i have a onkyo lap-301 and i have sound from my sub but just a clicking sound from my speakers what could cause that
Any updates? Did you install heatsinks?
I need to repair HDMI Main out. Im using big and heavy HDMI plugs so it has done something with the small pins. Cable and plug needs to be in a special way to get video output. Might need resolder. And a good old dust remove inside. Might also look at the fans. Havent heard them or the realy turning on lately
So I can get audio but no video out of any of my HDMI plug ins. Not sure what would cause that. Is have the TX SR806
same here !
sagiv harush I did the reset and works again
@@sagogago if a reset does not fix it, check if the HDMI level shifter chip (5V to 3,3V) might be dead
i tried the hair dryer method on the dts chip on my onkyo tx-nr717 that didn't work for me. i saw on other videos on you tube others used a hair dryer and after a few attempts the speaker matrix popped back up. i tried at least a dozen times did not work. i am thinking a heat gun may work or there is another issue. could be a power issue. any suggestions ?
Hi, still working after the DTS cool down?
How do I identify that particular chip so that I can try this fix.
Onkyo Av Receiver TX-NR609 HDMI Board Available ?
Hi my Onkyo SR.309 has hdmi out video on and off automatically. Is your treatment help,?
I tried to do a reflow on my integra dtr 40.2, put some flux around the chip and heated it up with a heat gun. After a month i had to heat it again, i put a heatsink on the chip and it still failes periodically every month or so. For a year i've been heating the chip every time audio goes out, not exactly an elegant solution but it hasn't kicked the bucket yet.
Also i had an issue with a back channel speaker that would only play static, out of pure curiosity, i put heatsinks on my entire hdmi board, and it fixed that problem
Are the heatsinks still working?
@@Truth-Machine5000 Haha, nope! I retired my amp, i couldn't get it to function anymore. I must have overheated the chip because i can't get any sound out of it.
Can liquid flux be used to improve reliability of the repair, or is flux only useable on the flip side of the circuit board?
Yes, almost certainly. But you'd have to remove the board from the receiver and squirt flux under the chip, heat it to reflow the solder, then clean with flux removal spray. If there are any high impedance pins, any remaining flux will create leakage paths. And in the industry, we use degrees Celcius, not fahrenheit. Lead free solder melts at 217C. Measuring the top of the package is fine, just know that the solder balls underneath will be at a lower temp, so heating the top to 260C is best. That's the max temp for virtually all chips when subjected to a solder reflow process.
Without flux, heating it up is ok but I don't think it'll last long. If he had some cold spray, you'd likely see the problem return.
Wow Maximus! You know your stuff! I have an HT-R990. I plugged in a composite video jack into a normal video input and the unit went into protect mode. Got it to restart again but the speaker grid lights stay on and no second click of speaker relay. Did volume up down and factory reset. No sound. What do you think? I opened the unit. 2 fuses blown to the speaker relays. I replaced them. AVR goes on off. I shut it down. Ideas?
hi, I tried everything to reproduce Dolby 5.1 on my Onkyo TXSR494, nothing to do, I can reproduce DTS and DTS-HDMA perfectly but I can't hear anything in Dolby 5.1 or Dolby Atmos. Could it be this chip's fault or should both formats have problems? thanks good work
I have an Onkyo TX-NR609 that does not power on. I unplugged it for 20 minutes and when I plug it in again it just keeps clicking every 3 seconds or so. There are no lights coming on when it clicks. Any ideas on where I can start looking for a problem? I have already checked the fuses and the big transformer has primary and secondary voltage for a brief second between clicks.
That's more complicated it sounds like it's starting up and at some point it's determining there's some kind of issue and then shuts down and cycles. look online for the factory reset button combination and try that
You think for one min they want that stuff to last?
what did happen to HDMI out issue?
I have silicon Image chips in my Onyko. What is the equivalent to the TI DTS chip to heat?
As far as I know, silicon image had designed chips to process the hdmi signals. I have a denon and marantz receivers that use various versions. The denon receiver had an sil9185 chip that failed, shorted the supply. Just removed the chip and ordered another one from China. Fingers crossed. I don't think TI builds a direct replacement part for silicon image, at least not for receivers 8 yrs or older.
Iv got the speaker grid indication but no audio out the speaker or pre amp outs i didn't try this yet but what do you think it could be the issue? I wanna use it as a pre amp for my Emerald physics 100.2se amp
By any chance, did you fix it ? I have the same issue and im hopeless
What’s the tool you use on the metal parts of chips
To attach chords or of the sort
Will this work to remedy the HDMI inputs as well ?
Works?
Interesting video. Do you have an idea where exactly you save the firmware?
What are the dimensions of the chip? I'm looking for a heatsink to install on it...
It's about one square inch
@@CatusMaximus Thanks, I took a 19 x 19 mm one.
I've Denon 4311ci it shows DSP 01 error no audio out (analog and HDMI I/P), rest of the things working fine how to fix this? Please help me...
I have an Onkyo TX-SR313 which is doing the same thing, will try this for sure. I have an SMT reflow oven at work and my job was multi-layer PCB design, so I should be able to lick this. Loved the sound my amp had... don't want to go through a whole repurchasing thing...
If you not put an hetasink on the chip an maybe an cooler to this area like you said, the failure will come back soon, cause the area will be very hot if the Receiver is in use, and before heating the chip up use flux and cover the chips around with kapton or aluminium band, and circle around with the heat gun not pointed cause overheating a spot. !
Gratulation that you could give yor receiver a scond life !
How reliable is the thermometer on the receiver? Did you ever check to see if it lined up with your IR thermometer?
I've got a txnr709 and the chip seem bad works when I heat it up to 350° but after it cools down and I turn it off it doesn't come back on. Do they sell new or refurbished boards ?
Onkyo were repairing them up to 2018
I have a receiver for this 875, silver.
From time to time he has a radio-like hiss when he's tuning in to the station. It always occurs in the right front channel of the tower.
This hiss does not last long, it stays for a while and then disappears.
Sometimes it comes back. Could you give me a glimpse of the problem?
I have already tried the ground loop, removing the ground plug from the outlet.
Impedance has also been noted.
I'm from Brazil, here nobody was able to help me.
I thank you already friend.
It help a lot for us Sir. Sir, do you have spare Spare DSP board for Onkyo TX-SR501. Problem dont have output and i found out a open coil and short AK4586 Chip.. Can you pls help if you know where can i buy the board or supplier. Thanks alot
Hello friend, were you able to solve it? I have a similar problem. When you replaced the dsp did you have to record any bios on it?
Thank you very much. I used some hint in the comments and applied 230C for approx. 1 minute.
I bought this Receiver for 170€ (used condition) and the issue with the DTS chip just appeared after the warrenty of the reseller ran out. I just applied your fix and now I am running some tests (and if everything works, I will install some additional heatsinks later). I will keep you updated, if everything works out in the future.
Some of these comments, lol. This was a wide spread issue across many manufacturers during some specific production years due to them all using the same garbage TI DSP chip. So before you "stick with" your brand of choice, keep in mind that Onkyo, Denon, Yamaha, Pioneer, etc. were all effected. Just like how they were also all effected by the janky ass HDMI 2.1 ports on the 2020 models.
Where do you order parts?
Onkyo doesn't sell parts for this anymore all they do now is allow you to register the serial number of a defunct receiver of the this era and they'll give you a 30% off a new unit
That chip went bad in my 2012 Onkyo. I used a commercial heat gun with concentrator tip to heat it but no luck. Found a Denon on Crutchfield for $300.
Hi, nice video, need help here, i have a onkyo TX NR 656 7.2 receiver , i have no display on the TV, both my main and Sub HDMI ports arent displaying picture , i have sound and the buttons work. Reset didnt work .pls help !!!
Hi
Great vid, thanks
I've tried this now a couple of times and last attempt I reached 330F. couple of questions
- Is this know to be a proper fix, even for a year or two? I ask, as mine is still not working when it cools
- What sort of temperature can we expect the chip to fail at? I’m using a paint stripping thermal gun…lol
I found that I just got lucky ( Issues have come back I now have to switch inputs around to get the speakers to work) sometimes you have to heat it up much hotter hot enough to get the soldier to melt, also Flux should be used.
Also I have since learned that some of these issues are due to the microscopic wires inside the chip itself failing.
@@CatusMaximus Hi and thanks for the reply.
I’m thinking the processor has had it, and on top of that I may now have blown part of the amplifier circuit, as it requires high volume now to get a decent sound level.
Had a look online and cannot locate replacement board for this, so I fear it’s time for a replacement unit. Quite shocked and disappointed at just how bad this thing has lasted, and the level of support for it. I don’t think I’ll be buying Onkyo again, even though it appears the TI chip is the culprit
@@CatusMaximus Hi
Just to let you know, I heated a couple more times using flux. Just ordinary flux from my soldering kit, using a brush to apply. I think temperature must have been approaching 400F easily, and am surprised the board didn’t fail. I also did a factory reset, as at one point the sound appeared muted. Seems to be working properly again now for the past week, so fingers crossed. Appreciate the help….you may well have saved me £600….cheers
A lot of these meltdowns show solder that has dulled in appearance which a drop or so of flux can help fix that problem.
Not on a BGA chip are you going to see dulled solder. Can't see under them.
I'm from Brazil and I have an Onkyo TX-NR 686 and the HDMI output (main) doesn't work anymore. The rest everything works. Can you tell me if Onkyo sells boards or do I have to have it repaired. I bought this receveir in the United States. Could you help me by sending me addresses.
sir, please help me, why is my amplifier like that, the brand is ONKYO, the AUX IN AND Fm radio don't work, it doesn't work, but when it's in the USB PORT, it's ok, it works, it's just that it doesn't take long to play the music, it dies a bit, it also dies when it takes too long Is it possible that my amplifier is an issue because the model is " ONKYO TX-SR313 ☹️☹️
My onkyo nr 646 sound is ok but still No dolby atmos and dts hd master sound please tell me what is the problem
I do not know I just made this video because I found this receiver and then read online about the DTS chip issue and just lucked out in fixing it
Catus Maximus how long has it ran since you fixed it? Just got a Onkyo with the same DTS chip issue and I’m wondering if it’s worth the trouble to go through your process.I only spent $15 for it so it’s not a big deal but it is a really nice receiver
I think we are on the same boat. I have a DTR 6.8 with issues with anything Dolby digital i.e. Dolby 2.0 surround, DD 5.1, EX, TrueHD etc, I'm at wits end on what to do, but hopefully there's a solution out there.
What receiver can have lifetime satellite radio subscription???
During the very early days of Sirius Satellite Radio before they merged with XM they sold head units for around $300 that had a lifetime subscription that was tied to the specific serial number of the head unit. that ended after they merged with XM so it's only the really old units that even have the possibility so just hunt down old Sirius satellite radios. It was a consumer contract when they sold those lifetime subscriptions so that's why they were never canceled it is also my understanding that they are not valid for online stream.
It's easy to know if you found one of those special units you just simply turn it on and let it do its Channel updates and you either have 150 channels or you have no Channels.
Mine Pioneer vsx322 only last 8 years, bought in 2013, person at Pioneer said need to replace the board,but the board is no more produced.😭
That's why I still keep my old Yamaha RX-V2400 & HTR-5890 THX 7.1 Receivers... They still work great and are nearly 20 years old. They don't have HDMI or support master audio but have better equalization from the microphone auto setup then this Onkyo.

Sir I see this video and I use Yamaha rxv665 avr and my avr display in suddenly decoder mode off but last time same issue display but automatically start speaker icon and on but today is a same problem see plz what is solution plz send me
Thanks for the tip, in case the thermal blower has to reach a temperature of 200 degrees? and for about 15 seconds on top of the chip? after that repair did you have a problem again?
Yeah it already needs to be redone it gets no audio unless I switch around the inputs after turning it on I'm just going to go back to my Yamaha
So what if u have the speaker icons but no sound?? I have Video too
Did you found the problem?
I opened up my ONKYO HT-R558 receiver, cleaned it with WD 40 contact cleaner, pasted a heat sink on the DTS Chip and the issue was resolved.
Did you clean whole onkyo with wd40 or only DTS chip? :D
@@achibbbb I cleaned the whole ONKYO with the Contact Cleaner spray thoroughly. Then placed a heat sink on the DTS Chip and it's been working perfectly since then.
What's a heat sink? Forgive my ignorance. I have an onkyo only left speakers are working

Thx for your help. How it works just fine again. Your video saved me a couple 100 €.
Next time when you want to disconnect the black cable just push it down.. And you can easely disconnect the cable without ripping it to peaces.. Nice video tho.. Love to watch it..
Yes I was unfamiliar with that connector and did butcher it that's for sure
Hi,
Thank you for your Video! I just fixed my Integra pre-amp by doing exactly what you did here. I was going to try the "baking" method until I stumbled across your vid. I did use the infrared thermometer, and it took a while to get the chip to get to temp. My first try failed, and the speaker indicator lights did not appear. I don't think I got the chip over 300deg f because I was being cautious. I tried again, and this time I let the chip get to 306deg f. I kept it on that temp for about 10 seconds. This worked!! I know nothing about electronics, at ALL, but It didn't look hard, so I figured I have nothing to lose. That being said, can you do a follow up vid to show what other chips might need the heat sinks, before I close it up? I'M not sure which ones are chips and which ones aren't.. that's how little I know. Lol. I got a heat sink kit off Amazon, and it came with a bunch of them. Thanks again for your wonderful vid!! You just saved me a couple hundred dollars minimum!!!!!!!!!
Hi, I heated chip to 185 C and sound come back. Now I have mounted heatsink to help cooling. Soon I will post video with all details on my channel I have recorder all procedure. Thanks :).
Thank you for helping me reset my receiver.
I also bought two with the exact same problems.
Why didn't you use any flux?
Also, are you going to mount some radiators over the DSP chip?
LE.: also, 115F (46C) isn't really too hot for that CPU especially since it's a fine pitch IC and not a BGA.
I need the update this video it turns out much of this issue has to do with the solder joints internal to the processor package and not the BGA grid to the motherboard.
I've already switched back to my old reliable Yamaha because my imputs already started becoming intermittent and I have to switch between inputs before sound will come out
great video! can you also show how to put the heat sinks on the chips you mentioned in this video,.
Thanks man! Worked like a charm for me as well. Here's hoping that it lasts...
What model did you repair?
I can't thank you enough for the break down and info you shared in this video. I've never commented on any video before, but I truly am grateful. I have a onkyo txsr601 and it runs the music in my shop, hopefully you saved it from a load of buckshot. I'm gonna head to HF now and buy a pen heat gun, and try it. Can I take heat sinks out of other stuff, cut em down and use them, or do they need to be specific sizes?
Know anything will work as a heat sink just make sure it's not too big and won't touch the other circuits around the chip and find some way to attach it
Look at some of the other comments some people have mentioned that using electrical contact cleaner as help too. Also with the heat gun you can make sure this is the issue just by heating it up to around 150 degrees and see if it makes a difference
I didn't try the 150 deg. I got it to 300-330 deg. ....I could smell hot solder, so I stopped and let it go back down to about 80 or so. And still have no speaker display. That was a couple hours ago, I just added some petroleum based flux, and did the same thing, its cooling now, I'll clean it off and see what happens.
You may have to try again at 375 to 400 that's the temperature of the ovens run at when they make these boards so even 330 might not quite be enough to properly melt it even if you do smell some flux.
The scale and breadth of this issue with Onkyo really has turn me off and the sad thing is is many Integra receivers also suffer from this issue. my fifteen-year-old Yamaha keeps Trucking along.
Hi to all. Did you ever replaced dsp chip? I have replaced it on my yamaha rxv773, and i bought updated version DPTP4. Inside was CPTP4. Now I have speaker icons, but no sound at all. Not even a test tone.
This is the same fault that caused the early XBox 360s to fail - I've even seen it in laptops. You'd think by now they would have realised this...
My guess is they do know and it's built in? The cynical me believes this to be true! Unit breaks= you trotting off to buy a new one 💰 for the company.
This is true. We need to consume more and more in order for these fat bastard companies to pay big dividends and huge bonuses. They know exactly how long something should last. Think about it. How come some old electronics seem like they are going to run forever? And in this day and age, they haven’t figured out to make solder as good at least as it was with lead?
I like all your videos Catus. No matter the subject.
thanks
just to provide a data point, my unit failed right around maybe 2000 hours. (i bought in 2012, and have it RAM in 2016, and today is 2020). i just check my total usage to this very day is just under 4000 hours, so it is very possible at the time of RMA it has less than 2000 hours.
so i think this may be less depend on actual hours, and more on the age of the receiver. 4 or 5 years maybe a good time for the problem to surface.
still quite impressed that Onkyo picked up the bill for it. the round trip shipping of a 50 lb receiver probably cost a small fortune.
Helpful video 👍
I never had a model like the one in this vid tore apart yet...
Are those yellow bias pots on the tops of the amplifier boards right by the heatsink there? How convienient if they are.
Crank em up! 😬
Thanks for the video and tip!
How many °C should it be heated to? How many minutes should it be at this temperature?
It is necessary to heat shock several times in a row?
Interesting, nice to see different content from your chanel.👍
Awesome video, it helped me to understand issues that I may be able to fix on other types of electronics. Have to ask, did it work after you reheated it?
OK your 2nd attempt was closer. But 350F won't do it either. I'd love to know just what is so therapeutic about heating that chip well below the melting temp of the lead-free solder required when that unit was made in that 2009+ era. Also, a chip temp of 120-ish is not all that hot. Probably does not need a heatsink.
Use liquid flux and heat to 250C (480F) for 15 sec. Let cool, spray flux remover.
Selamlar, Türkiye'den yazıyorum onkyo tx nr1010 Avr amfi hdm kartı arızalı bu yüzden yeni sürüm hdm kartı ile değiştirilmesi gerekiyor. hdm kartı tamir etmek istiyorum
Hello, I pasted the chip but I still don't have sound, do I need to heat it up more?
I found a heatsink from an old tv circuit board about the size of the chip. No problems since.
I have a HT R391 on the bench, no display, stb transformer voltage is fluctuating., disconnected its steady. Maybe its just a VR.
My Onkyo hdmi output is not working and Bluetooth wifi I need help with this problem (tx-nr676e
