Troubleshooting Onkyo Garbage Receivers for No Sound, No speaker relay click

[@SolidSleds]

I bought an Onkyo used a few years ago and it had no sound when I connected. I saw your video and decided to try your trick for the heck of it. IT WORKED!!!!! I don't care if it is a temporary fix, your video resurrected this boat anchor and made my purchase worth it. Thank you so much.

[@jsar4838]

Thank you once again! I did this method to my onkyo tx-nr414 half a year ago. Few days ago I lost the audio and I did this trick again. Enjoying good music again! Thank you:)

[@runepedersenDK]

Finally! Been watching this very interesting channel for a long time, been waiting for this. Got two of those recievers, a TX-NR579 (driving two Klipsch RB 51 used as computerspeakers), and a TX-NR 808 as main HiFi unit. Both are approx 8 years old.and they always had a lot of cooling space arround them, and were never abused. The 579 failed in 2016 and was put in a closet, and after I realized that there was an extended warranty, I send it in (2017/2018) and it was repaired (new HDMI board). Still working fine. The 808 never failed. Thanks for a very cool channel!

[@Fifury161]

Nice customer service - it's always good to prove out the fault and provide a cost of a proper repair! Thanks for sharing.

[@richardhalliday159]

Occasionally the BGA solder pads do not 100% flow in the cct. board manufacture and the odd ball may end up just having a ‘touch’ contact that may work and not show a fault until later. In and amongst my life as an electronic technician before retiring from the game, I was involved in a R&D and debugging role at a major digital satellite and cable receiver manufacturer and occasionally came across this problem, giving the chip a little tickle with a fine nozzle on a hot air gun sometimes cured the problem, even using an expensive professional rework station replacing. BGA (ball grid array) is a nightmare, you cannot guarantee that additional heat applied after original board flow will not damage the internal tracking of a multilayered circuit board, as you say, the bit of heat with a bit of luck will keep your board running a while but you end up repairing it as a freebie!! Keep your little films coming,I’m sure they help a lot of people

This trick worked for me. I am from Chennai India. Great and thanks to you.

[@pdxway]

Thank you! Thanks to your video, I decided to purchase a 300w heat gun from Amazon. Just two hours ago, I tried heat gun about 3" away for about 2 minutes. I tried power on twice and both times my 808 would have sound right away from cold power on. Will see how long this lasts.

[@obelixer9751]

First you could try to hold the CBL/SAT button while turning the power on. release and you see CLEAR... it switches off by itself after a few seconds and maybe that fixes the no-sound. it did with my TX-NR515. now my inlaw had the same problem with his TX-NR616 but didn't work resetting. so I gave him mine 515 which died a few weeks later. end of story I reflowed the DSP with no luck, then removed it and seen some bad contacts (hooray) cleaned, tinned, cleaned etc. but again no luck. 2 boat anchors :) Tho wondering if I can mod these to become "dumb" amps and surpass all the smartness build in these things. schematics where art thou?

Nice video. I've been out of repairing receivers and other things since 2001 when I was laid off and then ill after 30 years in the business. This looks more like a computer motherboard than an analog receiver to me! When I got laid off, these SMD micros were slowly populating the boards of the newer models. I've seen a lot of thermal problems on the older units of various descriptions like the one described in your video.

[@jebbj19]

Some are EXPENSIVE garbage. Thanks for helping. My TX-NR5008 preouts for fronts and center channels stopped working. You should have seen me scrambling to Martin Logan's help center only to find it was the receiver. Thanks.

[@makeminefreedom]

Great tip. I never thought of doing this before. It does makes sense that continuous heating and cooling would eventually crack a solder joint. Thanks for sharing.

[@12voltvids]

It is either a cracked solder joint or a cracked silicon die inside the chip.

[@vdochev]

It's the interposer inside the chip. If you heat it up things expand and make contact again. The bad thing is things also shrink... So, as the owner of the video said, it's not a proper repair, you need to replace the chip with a good one. And then probably provide good ventilation when using it.

[@GTAmelody]

[@nancyfansher4791]

I have been through so many Onkyo's. The last great trouble free one I owned was a TX NR901. Used daily until I just had to have HDMI. Even then the 901 was used in a garage setup for another 10 years with zeo problems. When I went HDMI, I decided to go with the TX SR805. I was so impressed with it that I bought a TX NR905 to get Ethernet input and moved the 805 to my front room setup. well, not soon after that the 805 video and sound. Tried to get it repaired, but Onkyo wouldn't honor. At that time I bought a TX NR807 on clearance to replace it. Not soon after the 905 lost sound. I was able to locate a TX NR5007 on closeout and picked it up. Again, Onkyo refused to fix the 905, so on the shelf it went. You know where this is going, not soon after the 807 failed. Lost Video, Ethernet and audio. I tried the 5008, but started having issues out of the gate with it and was able to return it. At this point I was done with Onkyo and switched to Denon. Of coarse the 5007 failed too, so I trashed the 805, and the 905, 807 and 5007 sat on the basement shelf. Years later Onkyo decided one time only to repair these units, but guess which model was left out? The 905 which I found to sound the best for Audio out of all of them. I sent in the 807 and 5007. The 807 is still sitting on the shelf since getting it back and I put the 5007 in my basement and it was still acting wonky when I got it back, but Onkyo refused to fix. None of the input buttons respond correctly and when you try to power down it will either turn zones 2 and 3 on or put it in pure power mode. after about 10 pushes it might finally turn off, but not before clearing all of your settings as if you did a factory reset. I would love to get the 905 back up and running and the 5007 working properly, but no one will tough them. :(

[@12voltvids]

I am currently using a 605 which was given to me last year. When my RC370 started acting up again after 3 years (after the light bulb fix) I put in the older 605 and use it just for TV sound. It doesn't work properly with analog inputs, as it won't convert them to HDMI like the 370 did so my VCR and Laserdisk is useless as they are remote mounted and not connected directly to the TV. In my setup all my equipment is in a separate closet, about 30 feet from the TV, so all switching needs to be done remotely. Since I still have analog sources, getting a new modern receiver that only has HDMI is not an option. I have resorted to plugging my VCR and Laserdisk player into an MTS stereo modulator and sending the video and audio over RF to the TV, and then the sound back to the receiver. Not an ideal setup, but at least it allows me to view VHS, Beta and Laserdisk analog sources. I don't use these much these days anyway.

Got one at the dump. You can bypass the HDMI board by (unit off) holding bd/dvd, press power and when display shows "hdmi :use" push power gain and it will toggle to "ignore", release bd/dvd. You just get basic audio inputs, no fancy AV. You'll have sound but no tone controls. Using Zone 2 you get tone controls.

My other JVC still strong after 12 years but using only the speakers that came with it out the box. Nice video.

[@FrozenHaxor]

Also from what I heard from fellow technicians, when Onkyo did the recall till october of 2018 where they fixed those for free, they used a board that dropped the DSP voltage rail from 3,3V down to 3V, most likely to lower the power that the chip needs to burn. Huge fail on behaf of Texas Instruments...

[@pierreevensmeneide700]

It works for me. I used an heatgun at maximum power for a minute on the DSP chip on my Onkyo TX-SR313. Thank you for the tip.

[@FlingwingNZ]

Do you think it is the chip that is at fault or just the solder joints? It would appear to me that reballing and refitting the chip would do the job...until the design fault of an expanding and contracting thermal environment caused the joints to fail again. Maybe a heatsink on the chip is needed??

I gave a thumb down too because of his blanket statement about "Onkyo garbage receiver". The chip was/is garbage not the receiver. He continually makes generalizing statements about overall product quality in a lot of his videos. He should have clarified by stating: "junk Texas Instruments chip." Onkyo makes some excellent top-notch products, I used them for many years. ALL BRANDS at one time or another suffer from poor or bad component quality, whether it's Marantz, Acoustic Research... whatever.

You helped a lot with my 709 before I paid Onkyo to fix mine I found that if you put the audio settings to DIRECT you can get the amp to come on in stereo.

[@12voltvids]

Not mine. When it failed it was dead even in direct mode.

[@spikester]

@@12voltvids I think the dead chip stops the protection relays from closing, so the audio is gone until that happens even in direct mode. I had an SR-707 repaired by Onkyo for free a couple years back that I bought in 2010, it worked fine since before selling it.

[@BeefyMon]

My TX-RZ800 died a similar death (I will try this fix shortly), but the analog and toslink inputs still work perfectly (assuming the unit isn’t set in a mode that require the dsp chip to process the sound). Dolby 5.1 works fine, as does All-channel stereo, and so on. I ran my blu-Ray player’s HDMI directly to the TV, and used an optical cable to feed sound to the Onkyo. I lost the higher resolution audio and Atmos support, plus the ability to switch video sources... oh, and the onscreen menu... BUT, it got me by until I picked up a newer model at a decent price. Incidentally, I wasn’t aware of the RZ800 being prone to this issue, but it happened twice (the first time under warranty, the second time, not).

[@boyceburns1823]

I've worked on this same problem and it is as you say, it is across the board but I don't think changing the DSP chip is going to solve anything. The problem is the extreme amount of technology compressed into that little chip. The chip is like a CPU in a computer, it needs a heatsink attached to it but the problem I've noticed is there is no mounting holes to hold the heatsink to the board, at least on some of the boards. (like the one you are showing us in the video) I've spent a lot of time and work on this problem and I do have proto-type solution in the works. Some of the boards have a thru hole on each corner of the DSP chip and with these holes I've attached a heatsink with a custom made mount to displace the heat generated by the DSP chip. Only time will tell at this point if it works. (fingers crossed)

[@craigkovatch7564]

Re-ball the chip. I suggest you take the board somewhere (if you can get the board out) and tell them which chip you want re-balled. If you can't find a place that repairs general electronics, a cell phone repair shop should be able to re-ball it for you. You could do it yourself, but it's something that has to be done just right. So you'd want to do a lot of research, buy the right tools and supplies, and practice on junk before you do it for real.

The trusty TX-4500 is a thoroughly vintage unit dating from the late '70s.

Sometimes I do get a bit of sound after the second relay clicks, but not always and when I do get some sound, is not clear and is crackly. If I try to increase the volume the sound will just cut out and will not come back. I have to turn the power off and back on, but the sound does not always come back. I may have to do this a couple times before the sound returns, but it is always crackly. Possibly something overheating????

It was a common fault of the era, drive by government regulation forcing too rapid a transition to under-tested new solder. A whole bunch of computer parts had the same problem. Laptop gpu's were notorious due to running hot and exposing the flaw in as little as _1or2 years!_ imagine buying a new laptop and bluescreening with HW failure in less than 2 years. Also, note that the fault use in a TI chip, not onkyo. Several other companies had similar problems, but onkyo had more *because they put the best of the best new chips available in even their cheaper units.* Most other companies were cheaping out on features in sub-$800 units, so most of those weren't affected. Things like dolby only or dts only models vs onkyo with both and vertical sound and auto tuning mic and more hdmi inputs and... It's sad the heaps of laptops and other electronic went to the landfill so the gov could put on the image of "saving the environment."

I have a Onkyo NR616 and an NR818 and they both went back to Onkyo for warranty repair for exactly the same fault! Great video, nice to know what caused the failures, now that my amps are repaired I have a 5V fan sitting above the rear of the amp (powered from the rear USB) to help stop it overheating again.

[@aksolartechnologieskriskan6668]

I have the nr616 with no video output

[@jahmezis45]

My onkyo shows speakers connected Bluetooth connected but no sound could this chip be the issue? I think there may have been some slight water damage.

[@AK-xu5sj]

I have an Onkyo M-504 that has a long lag before the servo relay clicks on. Any thoughts? Once it clicks on it runs fine.

[@nicholasbrown8384]

I would avoid using the heat gun due to the high risk of damaging the DSP and receiver because heat guns don't have the reliable temperature regulation that hot air rework stations do. Hot air rework stations will let you set the right temperature and come with smaller nozzles so you can direct the hot air exactly where you need it instead of cooking neighbouring parts

[@amihaikopel613]

What is the right temperature? What is the right duration time for the heat? I have a reflow station at work. I think I have the same problem, when I start up the receiver there is no sound. Then, I wait for ~15 minutes so the chips will get hot. Then I power off and on and the sound is back (till next time).

[@animarkzero]

@@amihaikopel613 The temperature you set depends on your rework station its between 350-400°C When you Re-flow watch the chip closely ! A microscope or a good magnifying glass is a must. The chip moves very slightly when the solder melts. Then you tap it very very gently to confirm that the solder is liquid. Stop heating immediately! If you tap it too much its game over unless you can Re-ball and have the right Re-balling grid!

[@martinvanderkaay2902]

Gidday Dave, I have a Onkyo TX-SR507 Receiver, that just stopped powering up about 12 months ago, ( I turn it on, and a few seconds later, it clicks off! ) Again, apparently a known fault, in the transformer or something; there was a recall and full replacement available up until around 24mth ago!? Apparently rather than a fix, repair shop said just buy another....I'm reluctant...any bright ideas please?

[@goatweedwillie5349]

I had my chip replace many years back but its at not sound again. Think its a different issue now, all my speakers show up on the display but still not sound.

[@JERELSALSERO]

and what this dts will not react after heating, so the chip is made defect by you with this heating procedure?

[@mikolhan1]

Hey @12voltsvids! You said your own Onkyo started to act up and then after a while stopped working completely. Was that „acting up” an occasional no sound on one channel perhaps? Have one that does that and starting to gather potential diagnoses to cross-check. Great video BTW! :)

[@christianbergeron1407]

Had same issue, did not believed it would work. Initially it did not, but after that I took the board off, so I can flip it, and did the light thing on the underside over the soldering and VOILA, it is now working! I will put a heat sink on that chip to hopefully have it last longer (I read that the sticker that come with cheap heat sink is not transferring heat correctly, so I will use thermal paste) Thanks for the info.

[@NFSgamingEvo]

My onkyo rz900 sometimes center and front channels doesn't work ,if I hit with my hand on the sides, it works. ,could be the chip?

[@rickc2222]

I have a onkyo HT-R580 from 2010 - with rca inputs (analog) in aux port - i can get sound if i change mode to "stereo - all speakers" but not in normal stereo mode...does that sound likely to be dsp issue? i hear relay click when i put in stereo-all speakers mode...

[@Outamyhead]

I just got an Onkyo TX-NR609 that looked almost unused, but same issue as this. Would placing a heatsink on the chip help with drawing away the heat and increasing the lifespan of it's use?

[@12voltvids]

Didn't help mine

[@Evermoregreen23451]

That’s magic. I didn’t know that you could fix chips with a light bulb. I know that you can fix soldering issues with a bulb or applying heat but not fixing broken chips. Amazing. Thanks for the insight.

[@12voltvids]

The fault is bad solder under the chip.

[@lightshine6044]

Do you have a video that shows how to build that halogen lamp? If i have to use heat gun what is temperature in Celsius i should set it to?Thanks

It was an old fixture i had taken down.

[@1090835tgfe45resxcvb]

I have a Tx-SR313 Av receiver, It has a really long delay when initially turning it on. Can take up to 15 - 20 min before it finally comes on, once it is on no problems works great, Is this a symptom of the dsp failure ?

[@toddnunley8591]

Wow, just purchased a Onkyo TX-NR575 for Christmas last years. Had no idea they had these kind of failures. I was in the electronic service business myself started in the mid 80s but by the mid 90s I gave it up. Hard to make money since consumer electronics was getting so cheap. The cost of doing service kept going up, the return kept going down. Also I got was pretty tired of working my arse off only to make the shop owners rich. Got into office equipment after that and did pretty well.

[@martinm9979]

onkyo did a recall few years back due to this issue . many ppl bitched about no sound video issue so onkyo caved in and did the recall. had my ht rc270 fixed for free. gowever all electronics mwde these days made like crap. cost 150$ these days in canada for diagnosis.

[@mw5905]

I have a TX-SV727 from 1996 sitting here that's been horribly abused over the years and is still crankin'... However, I also have an HT-R520 that has much better surround sound abilities and what not. he 520 started randomly emitting loud ass pops and cracks from the speakers one day. Sometimes I can switch surround modes and it'll go away. That got worse and worse until it now has no sound at all... Could this chip be the cause as well?

[@markusk.7621]

You are my hero! Did this yesterday on my Onkyo TX-8050 and it works again! The only problem was to get a 50watts halogen-bulb because (in Germany) it‘s not allowed to sell it anymore regarding energy efficiency, so there are only led- lights left. But at least I found one in the internet. Really fantastic! I will now just put a heatsink on the chip and maybe install a little cooling fan to prevent the chip getting too hot in the future. Thank you!!

[@0rigpumu]

How long do you have the 50w halogen lamp switched on to heat the chip?

[@markusk.7621]

I had it burning for 7 minutes and then took it off so that the chip was able to cool down.

[@markusk.7621]

7 Minuten, dann runternehmen. Ich hatte zur Sicherheit eine Alufolie über die Platine gelegt, in die ich ein Loch gemacht habe, sodass nur der Chip mit der Lampe in Berührung kam.

[@0rigpumu]

@@markusk.7621 Ich werde das mit meinem Pioneer sc lx86 auch probieren. Der hat genau die gleichen Symptome und ich hoffe sehr, dass es klappt. Anschließend kommt ein Kühlkörper auf den Chip. Pioneer kann keine Ersatzteile mehr liefern. Also Platine austauschen klappt nicht.

[@markusk.7621]

Wünsche Dir dass es klappt! Für mein Modell gibt es auch keine Ersatzteile mehr. Ich hab bei mir auch einen kleinen Raspberry- Kühler draufgemacht und dann zusätzlich noch einen 80mm Noctua- Lüfter mit low-noise Adapter eingebaut, der die Luft von dort weg aus dem Gehäuse zieht.

Started having issues with my HT-390 and then the sound stopped...No other video I found did anything to help.....this worked...Used a 1500W heat gun for about 3 minutes...let it cool for a minute and viola, I had HDMI ARC sound again....Thanks for the post...

I didn't have a heat gun handy. My amp is acting up again, will work on it again some day.

[@vortexor1]

Does it still work? Thanks and best regards

[@doublejay74]

Quick update: My receiver doesn’t initially work on start up so I apply the heat gun for a few seconds and it works. About a minute later, it’ll give out again and then I reheat it again and it stays on for the rest of the time I’m using it. The only downside is the heat gun is literally resting next to the receiver should it give out. I’m just waiting for the day it completely craps out. A new receiver would cost me around $400.00 from what I’ve seen on Amazon. Not bad but I’d rather not go there. Times are tough.

[@gryanm]

That's what I was gonna do...but my receiver is only missing one channel out so far. What temp should I use for a heat gun, and for how long?

[@hugocarmo77carmo81]

Hi! I have an old but loved Technics SC-CH700 system. My amplifier module SU-CH700 was cutting off, I saw in some foruns that soldering a 10nf ceramic capacitor on the pcb pins of the fan socket would do the trick. I did that, and when I turned on the amplifier, I noticed that the fan started working imedietally, before not... Then no sound from the speakers or the headphones, so I took off the capacitor, tried it again, still no sound... Fan always on... I think I did something wrong, all the other components of the system (tuner, cd player, equalizer) all have power, even the equalizer bars are working with the tuner input or cd, but no sound... Oh... Another thing, the amplifier has two relays, When it power on, only one "clicks"... Can You help me? Thank You. P.S. - I have the service manual...
