Onkyo TX-SR806 Digital Noise AV Receiver Amp Repair Fix

[@robinjohnculleton5365]

I bought my TX-SR806 12years ago. I started to have the HDMI switching issue and found this KZbin video. This is an excellent video and shows how to repair a high frequency HDMI noise issue but it can also be used to resolve the famous HDMI switching issue. Thanks For those who want to repair the HDMI issue: 1. Purchase 13 x Panasonic 100 mf 10 volt capacitors. Available on Amazon or other online stores. 2. There are 8 capacitors on the underside of the board and 5 on the topside of the graphics board which need to be replaced. 3. Make sure you are grounded and use an anti static mat with a wrist strap on your arm (really important). 4. Watch the video. Multiple tips which are very helpful. 5. Remove the case screws on the LHS and RHS and the HDMI port screws. 6. Watch the video again 7. Remove the graphics board (2 x cables) and edge connectors on the RHS by first removing the silver screw on the other board and then pull out from the left hand side to free the edge connectors. 8. Mark the 13 capacitors which need to be removed and remove them exactly the way NorCal says, plus old capacitor leads. 9. Cut the new capacitor legs so that the capacitors are fairly close to the board. 10. Note capacitor polarity (really important), minus to the flat side I the diagram on the board at each capacitor location. Apply new solder as you I stall the new capacitors. 11. Reinstall the board and connectors and use a tie wrap to hold the black cable back to the board. 12. Enjoy your reconditioned receiver and thank NorCal.

This tutorial was a lifesaver...I replaced seven 100uf caps on my Onkyo SR 806 tonight, the receiver is good as new!! Thank you!

[@EdOrcutt-webmaster]

Unbelievable!!! I've been leaving my amp on so its always warm to avoid the noise on cold startup. Then it progressed to the point where different channels would stop producing sound. Turn it on and off and all 7.1 channels would come back on for awhile. Ordered 20 100uf 10v capacitors, you only need 13 for this model, replaced all the 100uf 4v caps on both sides of the board and waalaa... like a brand new amp. I do recommend removing the tails of the old caps off the board as if your lazy and leave them in trying to solder over them they will stick to the soldering iron and drop back onto the board possibly causing a short. Thanks for this video!!!

[@bencohn3483]

Just completed the repair. Huge thanks for the video, super clear and concise. In my 806, I was getting terrible digital noise along with difficulty switching HDMI sources. I replaced all 100uF 4V caps and this baby's good as new. Saved me $600-700 on a new receiver, norcal, you rock.

[@eiconteudodigital]

Amigo, o meu receiver é o Onkyo TX-SR875. Esses capacitores que você usou servem nele talvez?

[@jimgloriosojr8133]

I want to thank you for this. I purchased 10 capacitors and replaced them per your video. I never did this before. Not only is the sound crystal clear, My HDMI problem also was fixed (my HDMI switching was bad) I found with Onkyo over this and they claim my year was the year before the ones that qualified for the repairs (bullshit). So im a happy person thanks to you. Great video!

[@chrisvanrooij7572]

From The Netherlands: Thank you very much! My TX-SR804 Onky had the same noice-problem. With your very clear video instruction I could fix it. I've replaced seven Capacitors of 100uF. Again, many thanks!

[@jonasjefferson2464]

I dont mean to be offtopic but does any of you know a way to get back into an instagram account..? I was dumb lost my login password. I would love any tips you can offer me

[@valentinleonel9619]

@Jonas Jefferson instablaster :)

[@jonasjefferson2464]

@Valentin Leonel Thanks so much for your reply. I found the site through google and Im in the hacking process atm. Looks like it's gonna take a while so I will get back to you later with my results.

[@jonasjefferson2464]

@Valentin Leonel it worked and I actually got access to my account again. Im so happy:D Thanks so much, you saved my account :D

[@valentinleonel9619]

@Jonas Jefferson You are welcome xD

[@utubesigninsux]

Thanks to you & all the other good folks that have put up info re theses amps. My TX-SR806 had the HDMI switching issue so bought the 13 100uF 16V electrolytic caps from Jaycar & set about it. Was lucky (if you call it that) that the previous amp owner had also had this repair done so the smd ones were already replaced so I just unsoldered all the bad ones & put the replacements in. Woohoo! Off it goes again.

[@norcal715]

That's awesome!

[@utubesigninsux]

@@norcal715 & that's thank to you :-) I don't suppose you have any info on a NAD C355BEE - mine looks absolutely pristine inside, (top & bottom of board) not a hint of anything being hot or burnt, however when the power switch at the back is turned on, there is a click, then a few seconds later a second click, then nothing, not even the led on the front is lit. :-(

[@things_that_click]

Saved the day at my house! My old Integra DTR-6.9 had the same issue and the same board, so I just followed along and had great results, I just had to pirate a cap out of an old modem and make the swap. Thank you for taking the time to make a great video to educate the masses!

[@JasperKuiper]

I was having problems with HDMI switching. Some inputs worked, but my Chromecast (working fine on my TV) for some reason did not. Anyway, I used this video to replace 13x 100uf capacitors, just to make sure, and it worked!!! Thank you so much for this excellent video, you saved my receiver (and my bankaccount).

[@legendforever7036]

I have tx sr 605 onkyo I'm facing hdmi to tv is not working this method will work on my receiver or not

[@MrMoto948]

Best fix for av amp video I have seen. Well done. Didn't even use an oven!

[@texasman007]

Thanks, I ordered 20 from Digikey today. I ordered 7 extras just in case. I went to two different stores today in Houston that I thought would have what I needed (Electronic Parts Outlet and Frys), but neither store had enough caps. I need a bare minimum of 13 and each store had 4 or 5. I'll leave an update after I get the parts and attempt the repair.

[@xyloeye]

I really miss your videos, Steve. By far the best repairs on youtube.

[@Me11oIngenuity]

Thanks to you I just fixed my Integra DTR-7.9!!!! You rule life! Thank you so much!

[@jalfd]

Thanks for video. Tx-sr806 slowly died over last 6 months. Replaced the 11 100uf capacitors on bottom of board where they have been getting cooked, used high temp. Fired up no more warm up noise and switches between hdmi inputs like it should.

[@marcoecca6398]

beautiful video. thanks for the advice, you have kept me from paying to a new card 'cause I thought it was a defective processor. despite technical, I still have to learn. thank you so much

[@wellseewho]

I have the exact same problem happened to me with a digital keyboard. Thanks for showing the debugging process. I have since located my issue and applied the same capacitor fix to my high ESR electrolytic capacitor. The problem went away after the fix.

Thanks for your detailed diagnosis and repair video. Would love to see pc/laptop motherboards diagnosis and repairs if you have done it too. Great work !!

[@DerekEmerson]

Nice bit of Journey in the background, nice choice in music

[@toreibjo]

You have an incredibly steady hand

[@kazimerguney4486]

You are the greatest..Saved my Onkyo..Thanks for this Nice video Nice presentation.

[@peshmadscientist1833]

Good shootin! My customer said the trouble got better as the set warmed up; now is permanent, so ill be looking for bad caps. Some newer madels have a genuine ic trouble but older digtal boards are condidates for capacitor aging.

[@eric3dmograph]

This video change my life!!!

[@NelsonBigGunP200Fan]

Ever worked on the onkyo TX nr series of avr recievers ? Those had bad dsp chips on thr hdmi board. I had a nr809 709 and 609 all with the same problem no sound except when pure audio was enabled. Onkyo fixed them under a recall for free. Even sent a box to me. They were great recievers when working.

[@LatinPercussion]

Very nice and clear explanation. Thanks.

[@lucasbretels]

Those Onkyo's series produces a lot af heat, so the damage will appear first in the smd elco's.

[@troyquigg4411]

Thanks! Just did this exact fix on the same model of Onkyo.

[@VauxhallKeith]

Nice clear video. Keep up the good work and thanks

[@narmadadistrict2206]

My Onkyo TX-SR875 gives Popping/Crackling sound in main Front Left and Front Right Channels. And its works ok only in Multi channel in mode with Pure Audio/Direct Audio sound mode. Its not works in DSP modes.

[@norcal715]

I think the customer had the unit stacked with something on top of it so years of heat shrank the tubing. If the caps were 105's they should be ok. I did a power output test to 100W X2 with no hum or ripple. Unless they are bulged then in audio application at 60 hz I have not had any problems

[@jeanvandame4054]

Same reciver but no video issue, and yes the cat always sleeps on top of my reciver no wondering why is failing

[@DizzzyKipper]

Thank you for another great trouble shoot tutorial.

[@DerekEmerson]

Nice bit of Journey in the background near the start

[@DerekEmerson]

😂 just realised I made almost the identical comment a year ago!! I sent you an email to the gmail address recently for some advice on an Onkyo 606 receiver

[@cristeastefan]

Hi! thank you for sharing with us the great work. I have a sugestion, i find to be very useful when you explain how to unplug some cable conections or jacks. please do more like this.

[@cyrillelevesque9309]

It worked like a charm !

[@wiggy7373]

plugged pioneer vsx 1123 into a dimmer switch, tries to power up but fails. how bad is it doc?

[@grantfullen9559]

Was the Onkyo TX-SR806 working with just a complaint of a weird sound ? Great Videos love to watch the troubleshooting process.

[@texasman007]

Thanks for the great video! I have the TX-SR806 as well. Mine is having the HDMI switching problem. This is apparently from faulty capacitors as well. I'm an I.T. guy, but have not really done any soldering in my work. Can you please recommend which capacitors (brand/model) and what type of solder to use. Also, would you recommend the capacitors that are rated for higher temperatures, since many people seem to claim that this problem is occurring because of how much heat the 806 produces.

[@tonygammichia8436]

What tools do I need for this? A soldering iron and replacement capacitors? How many capacitors?

[@NelsonBigGunP200Fan]

My parents had the sr606 and it developed hdmi issues. Onkyo repaired the hdmi board and it was working. But I believe it's due to bad caps on the hdmi board. At one point I wanted to get the 807 as an upgrade to my sr705.

[@hermiedelossantos5569]

Nice legit tech.good work.

[@carlosperez-gb1fk]

norcal715. I have an onkyo receiver. Worked fine before the move. Now, I turn it on and it shuts itself off after about 5 seconds. Can you help me? Thanks.

[@mrsemifixit]

Awesome. Could you have detected the problem with a multimeter (maybe set to read AC v?) or had to be an oscilloscope in this case?

[@usa3904]

Hi, can you tell me what is the distance between the legs of a large capacitor "71v 15000uf" to find a replacement for it?

[@mako9673]

I am having a problem with HDMI not passing through unless I restart the receiver a couple of times as well as a lot of blue artifacts on dark scenes. I am hoping this fixes mine. I ordered the caps but my model is a 706. I think many of these are the same basic card designs and the caps are all the same and in the same place. I have to say I will likely not buy another Onkyo receiver in the future.

[@mtoumi9471]

Hello please I Have Sansui A40 and only the left speakers work. The right speakers work with low sound and noise.

[@skip741x3]

Onkyo TX-SR805 is making an odd chirping noise that pings around the speakers...only does it when im listening to dolby digital plus signal from firestick when watcjing netflix or prime... it runs Very hot even when listing at low volumes ,though i hear the heat is common to these beasts...i put a fan over the right rear quadrant, looking at it from the front...this dropped temps a huge degree...also ran it with no lid and again it barely got warm...that lid Really traps alot of heat! anyway, i know others have had the chirps that ping pong around the speakers only during a digital feed thru hdmi..likely the hdmi board is overheating...curious if you found a specific component to be the cause? the fan keeps it at bay...any feed back appreciated!

[@BigEightiesNewWave]

Did it get the Nichicon upgrade ?😍

[@johningraham1950]

On that same circuit board, can you tell me what the voltage is for the three 470 M85 capacitors on the left hand side. i had the same noise problem as in your your video and replaced the capacitors and the noise disappeared. Still had the problem of the receiver not registering the hdmi input signals, so I replaced all of the 100 UF capacitors on both faces of the board. Unfortunately, i accidentally tugged on one of the 470 M85 capacitors and knocked it loose and now I am not getting any sound to come through. I am hoping that replacing this capacitor will resolve the issue. Thanks!

[@djtheob01]

Nice work! My onkyo clicks and cherps when I turn it on. Only for a few minutes then the enjoying clicks go away. Any ideas? (Digital sky box with hdmi) thanks buddy.

[@GrantsPassTVRepair]

excellent tutorial. Thanks!

[@norcal715]

AC coupling so the trace is always in the middle

[@trencher7]

If I only care about one HDMI to work is it an easier job? I only use HDMI 1 input. I have the handshake issue where eventually I will hear sound, but video does not show up.

[@ubuntututorials]

Excellent video. I have found a few oscillating regulators like that before. A quick diagnosis with a meter usually finds the output 5-10% lower than nominal. If I find one like that I usually check with the scope. What did the 3.3V reg measure on a DMM, if you got the chance to do this?

[@surinderdhiman]

Amazing skills 👏👌

[@scotteo1]

Nice presentation, where's your ESR meter?

[@norcal715]

I recommend Panasonic Capacitors with a 105c rating.

[@erizxcv]

Excellent... Thanks for the video.

[@saturnino697]

Hello, my name is Charles, I live in Brazil and I have a receiver TXNR-616. This receiver features "Signal not" in any font I select, but the ARC continues works.many videos on youtube talk about some capacitors, but as the model of the receiver is TXSR-606, I do not know which capacitors replacement. could you help me? Thanks!

[@rayovolt]

Good morning Norcal : When you get some time could you take a look at a comment or a question I asked on your Vizio no power no video ,won't turn off video you posted 6 moths ago, if you can help me understand it a little better,thanks for your time .We appreciate your superb videos and your way of teaching , keep it up . Blessings ! rayovolt...

[@vivenreddy]

Thank you for helping so many people with Onkyo receivers. I have a ‘no sound’ issue on my TX-DS797. I’ve tried different sources but there is no sound from speakers and headphones. I have also cleared settings. Could the capacitors be the issue or something else?

[@danielmcallister2942]

Any problem in using 25v or 50v 100ufd caps? I have some Nichicons in stock, but just those voltages. I know that typically a higher voltage is fine, but another tech is telling me that higher voltage caps can lose capacitance over time? What do you think?

[@eiconteudodigital]

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.

[@avinashpunjabi8893]

I have an onkyo tx-sr503 with a similar sounding digital noise, its a non-hdmi version, pls let me know which pcb could be leaking out that noise so that i could replace those capacitors.

[@OSD07]

Nice Video really appreciated. Sir I want a favor from you I am having Onkyo PR-SC 5508 AV Controller which have some issue no menu (OSD) for information is displayed on TV screen. But if you put source in HDMI in Back of receiver or HDMI in front video and audio content is display on TV. Secondly on the flip panel button setup is not working, but however it is working from remote , thirdly pure audio is not working when button is pressed nor the led light is coming on when button is pressed . Kindly request your good self to let know what to test and what will be probably fault . Thanks

[@micosan]

I really like this channel. And was wondering if you could help me with fixing my Harman Kardon HS200 AV reciever? I'm no electrician but very interested in this stuff. The reciever suddenly stopped all sound. And I was wondering how to troubleshoot the problem, so I can find the faulty part of my board. Do oyu think it might be only a capacitor issue when everything else works perfect except for no audio. Both sub and main speaker channels are silent, and I have checked that the speakers work. And I have the schematics of the board and a cheap oscilloscope.

[@meahall]

Hi, I have a big Onkyo tx-nr905 that produces a buzzing noise through the speakers (and headphones for that matter). When I power it up and the final relay clicks (significantly slower than the rest) the buzzing starts. With no inputs, the buzzing remains the same level at all volumes. When I plug in an input, the buzzing gets louder with increased volume. I've been looking through schematics and common problems, but I'm completely stumped. Any guidance would be really appreciated.

[@norcal715]

Can you tell me at what frequency you think the buzzing is? At 60hz or another frequency? Let me know.

[@meahall]

@@norcal715 It sounds higher than 50/60hz to me (my power is on 50hz frequency).

[@usa3904]

Is this a reliable model?Is it worth buying it on the secondary, after 12 years of operation, in what condition will the capacitors be there?

[@anno32]

good video. is the scope set to ac or dc ?

[@anthony2010707]

Thanks Norcal for your very interesting videos, i have a onkyo tx SR876 with rhe headpnones showing on the front display although they are not connected, any idea what may cause this problem, thanks.

[@norcal715]

There is a switch in the headphone jack that tells the microprocessor that you have headphones inserted. I would plug and unplug the headphones (the 1/4 size) several times to exercise the switch to see if it makes any difference.

[@anthony2010707]

Okay thanks for your reply, much appreciated.

[@alejandromedinaespinosa3833]

HI do you know why when I conect the optical input (from tv to reciver), its sounds good for a minutes but then it goes to trash sound (sounds terrible), i most to turn off the reciver but when I try to turn on again there is no sound, its a ONKIO HT-R530

[@navpers4764]

hi there , Awesome video as always . I`ve been watching your video`s for a while now and learning tons :) I have a question though regarding noise coming through the amp ....and it doesn't matter what button I push ,tape , cd, video....etc: I have a Kenwood VR-6070 amplifier . I was thinking maybe its the same problem that you just fixed here on your video . can you please help or steer me in the right direction . its the same noise as if you didn't have a ground wire hooked on your turn table. its coming through the speakers.thank you

[@izzzzzz6]

Do post 80's Onkyos ever not break down? All i am getting is Onkyo repair vids in my suggestions.

[@eiconteudodigital]

it happens just when it's cold. Is it mandatory to change the chip, do you risk burning the device or the speakers? here in brazil it is too expensive to repair onkyo.

[@evidentsavant12]

I have a question for you. I have a Harman Kardon AVR 125 receiver which I purchased in 2002. Recently, while playing a downloaded video on my ps3, using ps3 media server to stream from my pc, the right speaker, the left satellite speaker, and subwoofer seem to be quieter when compare to the rest of the system. Upping and downing the speaker setting from 0 db to +10 db doesn';t seem to change anything. Can you please help. Thank you.

[@thingsdemystified]

Thank you so much for this! I only replaced that one same capacitor in my TX-SR706, and it fixed the problem. I'm going to leave the other caps alone because I don't want to mess something up. If it ain't broke, don't fix it right? =)

My Onkyo TX-SR803 has a similar problem, it only makes some strange low pitch noise and starts rising to high pitch, it will only do it when i first turn it on and it will go away after about 5 minutes, will this mean it will require the same repair?

Onkyo and Denon. If you look around the internet how many problems of sound and video in series ! their receivers are showing, and this companies don't make a recall, dont give any attention or respect to their consumers. The truth is that they don't care about any of that, they just want your money. I´ll never buy another receivers of this companies, and for sure I will tell to my friends to do the same.

[@thingsdemystified]

[@lucasbretels]

I use an ESR meter, to locate wrong C's! in circuit.

[@mdzacharias]

Good job! Don't like the Onkyo's. They place that HDMI board right on top of the regulated power supply board; dries out those crappy caps and makes them fail even sooner. They do it on purpose. Bastards. They're not even nice to you on the phone. Yamaha and Denon-Marantz are much nicer people to deal with.

[@pns712]

Hi, I have HT-S9400 THX model and it stopped any sound from speakers. How to fix it ? Looks like i have Main AMP board issue.

[@norcal715]

Is it in protect mode? Do you have a DC offset on any of the channels. Start by looking there
