I bought my TX-SR806 12years ago. I started to have the HDMI switching issue and found this RUclips 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.
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!
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
@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.
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!!!
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.
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!
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!
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 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. :-(
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).
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.
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.
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
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 !!
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.
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.
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.
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.
😂 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
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.
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?
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.
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?
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
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.
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!
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.
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.
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.
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? =)
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
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!
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.
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?
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.
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.
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.
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.
Thanks and great stuff, I have exactly the same model, looks like i messed up speaker connections on the back and unit stopped working, next time i turn it on, a red light keeps blinking. How do i fix it?
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
Thanks for the video. You make it look easy. I am newbie with my only experience being resoldering obvious solder faults. I have an old Pioneer VSX-d309 that started buzzing on startup, then after a while stopped working all together as the display shows "power off" and the protection circuit shuts the unit down. I have the schematics. Any ideas on how to proceed Any help would be appreciated.
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.
I have this exact unit, it is powering up and then powering right back off. I really was excited to save up and get this receiver but Onkyo let me down. Within the first year with minimal use it is now an expensive paper weight with no warranty.
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.
i changed many other capacitors what lost its capacitance on the almost same board TX-SR706 , but not this one )) , and after i changed this one capacitor the noise disappeared. AVE NorCal715!
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.
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.
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
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!
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...
Changed capacitor as described on same onkyo model did not help. Multimeter still shows continuity. What can i do? I have constant humming issue via speakers even on mute.
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?
Man... I have a sr705 with the same issue+ no hdmi and I've done a full recap changing 82 caps on the hdmi board and it still makes that noise but the hdmi started working at least.
i have a divinci dv-606 5.1CH surround receiver amplifier the sub woofer work good so do the speakers but when i hook up the speakers to the sub i get a buzzing sound if you can help that would be great
Hi I have Onkyo TX-SR875 and it has popping and crackling sound on front and surround channel. I try to rewire speaker connectors and try with all different inputs but not succeed. Please help me to solve this issue.
hello sir, please guide me to fix av receiver ir issue. my receiver model is HT-R592. it is not detecting remote. I checked remote against phone camera and its working fine. please help. thank you in advance
hi will you please let me know why my rx-v465 av receiver does not out put the video perfectly it comes yellow and sound is good how to solve it I checked all cables nothing bad please suggestion me what I do change the capacitor around the regulator or what I do?
Hay man..i'm a bit desperate cause my board where the DTS processor is looks different, but my model is Onkyo HT R 390. During a movie, some robotic interference was heard from all channels(like when u loose phone signal) and after some radio "shhhhh" appeared. Now there is no sound at all((( HELP ME SOMEONE, PLEAAAASE! I miss my sound! TIA P.S. i don't own an oscilograph and here in the Canaries very little people that really repair things...
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.
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.
I bought my TX-SR806 12years ago. I started to have the HDMI switching issue and found this RUclips 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!
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!

You are the greatest..Saved my Onkyo..Thanks for this Nice video Nice presentation.
Was the Onkyo TX-SR806 working with just a complaint of a weird sound ?
Great Videos love to watch the troubleshooting process.
This video change my life!!!
Very nice and clear explanation. Thanks.

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?
Do post 80's Onkyos ever not break down? All i am getting is Onkyo repair vids in my suggestions.
It worked like a charm !

Okay thanks for your reply, much appreciated.
Always love to watch your channel. 👍
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?
Nice presentation, where's your ESR meter?

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
Same reciver but no video issue, and yes the cat always sleeps on top of my reciver no wondering why is failing
Did it get the Nichicon upgrade ?😍
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!
Hi, can you tell me what is the distance between the legs of a large capacitor "71v 15000uf" to find a replacement for it?
Nice legit tech.good work.
good video. is the scope set to ac or dc ?
Those Onkyo's series produces a lot af heat, so the damage will appear first in the smd elco's.
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.
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?
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.
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.
plugged pioneer vsx 1123 into a dimmer switch, tries to power up but fails. how bad is it doc?
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.
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.
Thanks and great stuff, I have exactly the same model, looks like i messed up speaker connections on the back and unit stopped working, next time i turn it on, a red light keeps blinking. How do i fix it?
You probably have shorted output transistor(s) and possibly drivers in the channel that shorted out.
NorCal715 thank you. Hopefully i will be able to find someone to fix it.
Amazing skills 👏👌
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
Thanks for the video. You make it look easy. I am newbie with my only experience being resoldering obvious solder faults. I have an old Pioneer VSX-d309 that started buzzing on startup, then after a while stopped working all together as the display shows "power off" and the protection circuit shuts the unit down. I have the schematics. Any ideas on how to proceed Any help would be appreciated.
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.
I have this exact unit, it is powering up and then powering right back off. I really was excited to save up and get this receiver but Onkyo let me down. Within the first year with minimal use it is now an expensive paper weight with no warranty.
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.
i changed many other capacitors what lost its capacitance on the almost same board TX-SR706 , but not this one )) , and after i changed this one capacitor the noise disappeared. AVE
NorCal715!
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.
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.
Can you tell me at what frequency you think the buzzing is? At 60hz or another frequency? Let me know.
@@norcal715 It sounds higher than 50/60hz to me (my power is on 50hz frequency).
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
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!
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...
very impressive. how and where to start the search always baffles me.
I recommend Panasonic Capacitors with a 105c rating.
Hello
please I Have Sansui A40 and only the left speakers work. The right speakers work with low sound and noise.
Thanks
Changed capacitor as described on same onkyo model did not help. Multimeter still shows continuity. What can i do? I have constant humming issue via speakers even on mute.
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?
Man... I have a sr705 with the same issue+ no hdmi and I've done a full recap changing 82 caps on the hdmi board and it still makes that noise but the hdmi started working at least.
just repaired my problem. turned out the xm sat radio board was faulty. just unplugged it and now the receiver works like new
Hi my only HT R390 have a same compliant,can i change the capacitor? Pls solve issue
have TX-NR 906,AFTER isolating source of thumping sound in sub woofer - 2 thumps every second-source is definitely receiver. what shall i do ? thanks
i have a divinci dv-606 5.1CH surround receiver amplifier the sub woofer work good so do the speakers but when i hook up the speakers to the sub i get a buzzing sound if you can help that would be great
Hi I have Onkyo TX-SR875 and it has popping and crackling sound on front and surround channel. I try to rewire speaker connectors and try with all different inputs but not succeed. Please help me to solve this issue.
what is hsr and how can i fix surround speaker terminal not working it's a pioneer vsx-d511 tnx
AC coupling so the trace is always in the middle
hello sir, please guide me to fix av receiver ir issue. my receiver model is HT-R592. it is not detecting remote. I checked remote against phone camera and its working fine. please help. thank you in advance
Denon avr 486 or 1706 red light blinking and shut down avr please help me. I love my avr
My receiver Oknyo make noise and than shut off no speaker Icon and no sound how much it's cost for repair?
hi will you please let me know why my rx-v465 av receiver does not out put the video perfectly it comes yellow and sound is good how to solve it I checked all cables nothing bad please suggestion me what I do change the capacitor around the regulator or what I do?
abhisek bhandari please
"digital noise on when cold" was the complaint
Please, can you tell me the specifications of the capacitor you used for replacement, thank you.
I totally messed my hdmi board up trying to do this fix. Can anyone tell me if they know where to buy an hdmi board from.
Hay man..i'm a bit desperate cause my board where the DTS processor is looks different, but my model is Onkyo HT R 390. During a movie, some robotic interference was heard from all channels(like when u loose phone signal) and after some radio "shhhhh" appeared. Now there is no sound at all(((
HELP ME SOMEONE, PLEAAAASE! I miss my sound! TIA
P.S. i don't own an oscilograph and here in the Canaries very little people that really repair things...
Try heating and cooling various parts of the receiver to see if the sounds change.
I HAVE ONKYO AMBLIFAIR TX_ SR875 RECEIVER IS PROBLAM I NEED YOUR HELP
Email me norcal715videos@gmail.com
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.
Onkyo is trying. care.onkyousa.com/na/003_2012.php?country=USA
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.
I use an ESR meter, to locate wrong C's! in circuit.
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.
Is it in protect mode? Do you have a DC offset on any of the channels. Start by looking there
