Onkyo AV Receiver Repair

[@jarrodobrien2253]

I picked one of these up off the road in Mosman with a pair of Wharfedale speakers. The speakers are fantastic, the amp is doing the same thing. Going to give this a go, thanks for the effort of making this !

[@NearFarMedia]

Nice, let us know how you go!

[@EduardoVargas-pb1gf]

Thanks for this video, it saves me a lot of time. I have an HT-R530 Receiver internally very similar with the same issue. That 0 ohm resistor mentioned in the end was open and the super capacitor going bad. Now working good. Thanks again

[@ronw4072]

Thanks, this would have to be the best best diagnosis videos I have come across. I have a no sound issue with my Onkyo TX-SR313 that you can hopefully point me in the right direction to try and rectify. At one stage it was not powering up due to circuit protection but came good after going through the reset procedure. Worked fine for a while after that then I started getting delay in the audio coming through with the delay progressively becoming longer. It was out to some 15 minutes and then progressed to no sound at all. Visually inspection shows no obvious burnt components / bulged caps. I have eliminated speaker relays as the issue as they click in ok and it would be unlikely that all 5 of them are faulty. A lot of posts talk about bad caps / DSP chips on the HDMI board but I am getting video out (setup display works) and HDMI input is being detected ( If I switch output between RAW / PCM/ Dolby on source TV signal the display on amp changes accordingly). Amp also turn on / off through HDMI CEC function. The one odd thing I have found though is that the service manual test procedure that displays firmware brings up a series of ?????? when I query the DSP chip. Any ideas where I should start with this??

[@neocube3215]

Thanks - I've save a lot of time when I saw damage connections near backup battery (~18:00) - I repaired my TX-SR503E :)

[@YCbCr]

I've just had a TX-SR501E from the local flea market, seller insisted it's a Texas IC blown out, cheap to fix. Well it ain't that expensive it seems, same cap went bad, with no visible damage to the board - though i'm not sure about the vias. That was quite a red herring to chase in the beginning for me too, power rails, circuit diagrams and whatnot. Thanks for the video, i might have taken a few more hours measuring about! :)

[@NearFarMedia]

Glad it could help! :)

[@DhakaMusicOmar]

that was an awsome way to figure out the fault. good job

[@verada97]

EXCELLENT JOB !!! I have Onkyo TX-DS989 with the same symptoms - stand by OK but no powering up. Where are base? I am in Melbourne Australia

[@fullwaverecked]

Great troubleshooting techniques! Thanks!

[@achimlaurentiu6905]

I have an Onkyo tx sr506 amplifier that had a defect in the rear left channel. I repaired the defect but I did not find in the service book the table with the voltage values ​​on the measurement terminals for adjusting the idle current. Do you know the corresponding voltage values ​​for all channels for do current readjustment for all channels?

[@sj460162]

Very imformative thankyou. This has just happened to mine!! The standby light is on but the unit doesnt turn on and there is no click? Is the standby light still on a clue? Do you have any guesses? Thanks

Brazil, Obrigado salvou meu ONKYO 👏👏👏👍

[@makinjica]

Hi , i have Onkyo TX-SR702 , runs 30sec on screen reads ThermalProtect then it shuts it self down . One part of internal board is extremly hot , its heatsinked 4 transistors or mosfets . @ 1:48 its that heatsink to the right side of those 2big caps . Its old but still gives great sound .. Repair of retire ?

[@NearFarMedia]

I would check for shorted transistors/mosfets first up. If one is shorted it could be heating up causing the amp to trip. If that is all it is, it won't be too hard to replace them and get it running again.

[@ROGUPA]

Mr. I have the HT-R550, its displays turns off after a few minutes. I am not a certified technician, nevertheless I found out when the Cirrus Logic IC CS42518-CQZ got heat the displays fails... Applying circuit board cleaner the propelent cools it down and the display turns back on AGAIN for a moment... At this point I have the circuit diagrams and I already ordered a replacement chip JUST IN CASE the IC is damaged. I suspect it is not and MAYBE a surrounding capacitor is. I'll try to check the capacitors... in the meantime, I'll appreciate any comment regarding this issue. Greetings, from MX Rodrigo

[@jedfehrenbach9470]

This is the most helpful video I have found hands down for working through schematics. I originally had the same issue (intermittent no power on, only standby), but now it seems like it has morphed into a worse issue. It does power on when I plug it in, (and I hear relay click, and speakers will play, then randomly shut off after a few minutes). But none of the front panel buttons work anymore (except the volume pot). So I took it apart, and started checking pins with a volt meter. The two 13v outputs from the standby transformer that feed over from power board to the microswitch area are both outputting 19 volts!! Yikes. Is this a bad transformer? The area around the standby transformer is oily also, but I am not sure where the oil came from. I am not sure what to check/test next.

[@NearFarMedia]

I'd start by looking for leaking capacitors and the like. Also, check if any voltage regulators are bad too.

[@jedfehrenbach9470]

@@NearFarMedia thank you for the tip, on to that next! It's been a fun journey learning how to test various electronic components, and maybe saving a few things in the process from heading to the landfill.

[@Lowkey_nxthxn]

So my avr started to crackle and I had it since 2017 and out of nowhere it decided to show me symptoms so I’m not sure how stop the speakers from crackling

Hello! Where can I go to get my Onkyo rs603e receiver repaired? Need help purchasing parts for it!

[@Luke-12V]

hello, great video, hat down, please advise where to look for a fault, it plays just fine, and then it turns off, as if some component heats up, I have the same amplifier, thank you very much 🙏🙏🙏🙏

Hola..desde celaya GTO.. México..es normal que los receivers onkio..se calienten en encendido.. gracias..IMG

[@lelandclayton5462]

Well done sir. I've brought home a few Onkyo AVRs mostly the TX-NR555 models and its always a output transistor that gets blown. I don't think they use Super Caps anymore to help retain the programing.

[@themisunderstoodgorilla7030]

Interesting, i have an Onkyo AV receiver that turns on but wont boot, as in pressing the power button turns it on and you can hear some relays click, but no power to the LED screen and doesnt make music. might have to take a look, im guessing something simple is blown and no power to the control unit

[@milnuevesecenta]

Hi, I have one front speaker for same receiver that is not working, is any way to fix it?

[@NearFarMedia]

I would check the amplifier section for the front speaker. That would be the most likely location of the fault.

[@milnuevesecenta]

@@NearFarMedia thank you.

[@humairaejaz1910]

From where to get a chart sheet for different model details

[@NearFarMedia]

I just use Google to find service information on the unit, or a close enough similar model.

[@johnb4467]

Hi! I have a similar receiver but different issue...and if you might have some insight or two cents I’d be greatly appreciative! It’s an old TX-DS797, a tank of receiver that’s still in regular use. The front display no longer lights up. It was inconsistent for a good while (sometimes worked, sometimes not) but now stays off. Audio is fine. There just happens to be a 797 display on eBay right now and I grabbed it. Should it more or less modularly plug right in (assuming it’s even the problem) or is there soldering & such that will likely be involved? Hope you don’t mind the question, and thank you! :)

can you help me onkyo Sr373 in standby mode 3.3V and 5V standby voltage is there But no Indicator on front side set is Dead caution

[@cscooper2000]

Haha! I was on the edge of my seat hoping the battery cleanup would work. I was JUST as excited as you when you powered it up and exclaimed, "it's working! I fixed it! " Lol Way to go! Riveting KZbin! I've had a newer Onkyo r380 go out on me last night. In the middle of watching TV I heard a bit of a "plossive" sound and then the unit went into protective shut down. I've followed the troubleshooting steps (unplug everything. Wait an hour, etc.) but it won't come back on for more than 2 or 3 seconds before shutting off again. Any ideas?

[@NearFarMedia]

Hah, yeah, I was pretty happy it worked in the end. :) If you can find a service manual for your model or a similar model, there is often more advanced troubleshooting steps to narrow down what part is faulty inside, then you can start tracing the schematics to narrow down to the exact location of the fault as I did in the video. I know Onkyo had a bit of a problem with bad capacitors for a while, but I'm not sure about the latest units.. Might be a place to start looking to begin with...

[@Lifeless11111]

Wonderful fix... loved it

Hi well done on fixing your Onkyo reciever. I have a Onkyo reciever TX-NR838 and the power comes on for three to five seconds then turns off. I dont know what the problem could be . Could you have a solution for it. Please if you can get back to me. My name is Michael. Thank you for your time.

[@NearFarMedia]

I'm not sure without looking at it myself unfortunately. Have you done the usual check of power rails and looked for any leaking batteries or capacitors?

[@uprajsingh]

when i wiggle the backpanel where speakers are connected on the AVR or when I increase volume then sound suddenly comes on all speakers. Is that a dry solder or how does one fix that please?

[@NearFarMedia]

I would check and clean any connectors between the circuit boards inside, and check for dry or cracked solder joints. My first suspicion would be the solder joints for the speaker terminals as they would get a bit of force applied when connecting the speaker wires.

[@uprajsingh]

@@NearFarMedia Thank you NFM :) I will open it up and try ! Its a good old Onkyo sound, don't want to sell so definitely worth a try plus memories more than anything.

[@Brian-Burke]

Nice work. I'm about to repair a Harman Kardon receiver. Do you need to discharge any residual power from capacitors or whatnot?

[@NearFarMedia]

It's a good idea to leave the unit off for a while to let the capacitors discharge.

[@blueandbanana]

I don’t have a lot of your cool gadgets but can you show us what a bad diode, transistor, capacitor looks like and how to take out the old components and put in new components please?

Hello great job with the repair. I have a question... I have an Onkyo TX-NR535 that has stopped working. Recently I had to turn off my breakers repeatedly while installing a smart light switch. Since then my receiver has been making a clicking sound and won't power on. The sound is coming from the Power/Stanby button. Any suggestions as to what the issue might be?

[@animarkzero]

Sounds like some capacitors are dead If you have an LCR-meter messure the ESR of the caps in the power supply. If you dont have one you can try to point a hair dryer at the caps while powering on!When it turns on you can spray the caps with upside down can of air to cool it back down and watch see the dead cap

great set of fix it videos mate! i have a Yamaha RX-A1080 rcvr . one channel has distortion. i want to fix it, but i cant find any service manuals or schematics for the rcvr. do you know where i can find one or buy one? keep up the great videos. cheers

[@NearFarMedia]

Hmm, looks like a recent model, does it still have warranty? Newer models are generally harder to find info on as the service info takes time to 'leak' onto the internet for us mere mortals to use. Here is a link to a possibly similar model that might be close enough to use: elektrotanya.com/yamaha_rx-a1030_rx-v1075.pdf/download.html

Hi mate, enjoyed your intelligent and productive utube demo re Onkyo amp. I have a tx-Ds 656 since new over 20years and still gives a sensational sound for both 5.1 surround sound and music and to when listing quality 2 channel music via Bose 701s. Recently started a speaker hymn and spoken with some local tech’s to inherit noting but poor unsubstantiated expressions and commentary. I have since try to reach Onkyo australia but no go. I’ve been told by some armatures that it is due to aged power supply’s drop value?? And requires a transformer replacement. Can you please assist or direct me to a credible tech!! Within south east suburb in Melbourne. Thanks 🙏

[@NearFarMedia]

Sorry, I'm in Japan and have only visited Melbourne a couple times so I don't know of any techs. I do all my own repairs too, so I never needed to find someone else. :D

[@pidomotovlog3260]

Hi i am from philippine can i ask where i can buy hdmi board for my onkyo tx-sr608? Really appreciated if you reply this.thanks..

[@NearFarMedia]

I'm not sure where to buy spare parts spare from ebay or Onkyo. Sorry I can't be of more help. I do know that some models had problems with bad capacitors on the HDMI board, so replacing all the electrolytic capacitors on that board with good quality capacitors might fix the problem maybe.

[@stormkhan4250]

If done some searching around about info on this issue too and it appears Onkyo put in capacitors rated to about 80 degrees on these boards. Unfortunately, the position of the board inside the unit is near the top...where all the heat rises to and the capacitors suffer for it. As NFM has said, if you replace the capacitors, use 105 degree rated ones. If that fixes your problem then I'd suggest placing something like a 8cm diameter 12 volt fan (from an old PC or something) on top of the unit over this board and have it on when you are using the unit. This helps suck out the hot air and keep that HDMI board cooler to prevent it heating too much.

[@remusn74]

Great video! I have an HT-R558 with no powering up problem. At the service center they've said it is the BCHDM-0678 HDMI board but seems no one on youtube has posted a fix for this .. Just other HDMI board model. If you can be of any help I would gladly send some Paypal cash.

[@NearFarMedia]

I know there was a big problem with the electrolytic capacitors on the HDMI boards in Onkyo amplifiers a while back. There was a 'secret' service bulletin that Onkyo released to their service centers about it. I fixed another Onkyo amplifier by replacing all the electrolytics on the HDMI board a number of years ago. You can remove all the existing surface mount ones and replace them with normal through hole parts (Judst cut the legs short and solder them directly to the pads). Just be sure to use good quality capacitors with the same capacitance rating, no lower voltage rating (a bit higher is ok) and at least 105degree rated.

When you guys fake repair videos you always make your self look smarter then you are , thats a give away there is not a lot of mistakes if any here . If this was a real video you would make 10 mistakes before finding that thing . I do repairs also thats how i know , i know most of the video is totally fake , what i dont know is did you actually brake the cap your self just to have a repair video to make or it was actually broken . I would bet it was totally fine
