I know this is an old thread, but I had a 2 905s/ 906/ 5007 and all suffered from HDMI failures. The culprit is known, the caps on the board were not thermally capable of handling the heat generated from the HDMI chips...

If it's not a BIG screen, it's not a theater...

Old thread? people are still having problems..

My Onkyo TX-NR717 is sitting here packaged ready to be picked up by UPS and shipped to Onkyo in Germany for the HDMI failure thingy.

I've had it for 4 weeks... then suddenly, no more audio.. the speaker icons wouldn't light up.
Found the hair dryer method, that revived it, but I thought screw this, probably only gets worse.

Now my question is what do they do over a Onkyo?
do they change out the board?
is it really the caps or was there something as well with the chips?

If you get it back is it okay like that? or should I still install some kind of cooling system like a fan, or heatsinks on the chips??

You had video but no audio? What is the hair dryer method?

I have an 876 that I just repaired and replaced the caps and it is back in service.

I don't know what Onkyo repair centers do, if I had to guess, I would say the center orders a new board and do a swap. Then the new board will most likely contain the same caps. Probably not what we all want to hear but that's just my opinion of what happens.

You guys are talking about two different problems. The NR version receivers (network) are the models that are covered by Onkyo's extended warranty. The HDMI failures in those models is caused by a bad chip that TI supplied for the HDMI board. When the repairs are done, a new HDMI board (with a revised chip) is installed. It has nothing to do with the caps.

The older SR models (non-network) HDMI problems were due to bad caps and heat. If you replaced the caps with versions that were speced properly for the heat, then you won't have the issue again. If you just replace the HDMI board with a standard OEM board that has the original under speced caps, then yes, it will fail again.

Ah, indeed thanks for clearing that up.
So I'm good once it's back from Onkyo.

Well I found a video on youtube with someone heating up the hdmi card with a hair dryer and the Onkyo would turn on and play sound again.
I tried it, and it worked, suddenly the icons of the speakers would reappear and the sound would work.

Anyway I'm glad it's at Onkyo and hopefully it will be back soon.
I'm now running a Kenwood KA-5090r into the Dynaudios, just the mains, and damn that certainly doesn't cut it if I compare it with the Onkyo.

Ok, now I understand, in your situation, the solder joints loosened ever so slightly and heating it up reconnected the joints. It sounds similar to what I've done in the past with a computer graphics card. I put the graphics card in the oven and heated it up for a duration of time to have the solder reflow. Look it up to see if it will work for those who can't get Onkyo to repair/replace. Only issue I see if if there are plastic connectors on the card.

Just got word from Onkyo, amp is repaired and goes to UPS today, so I'll probably have it back on monday.
This isn't bad at all, I had to miss it for one week.
and even best of all, I bought the Onkyo 717 in an outlet store for 299 euro's

I'm considering picking up a used sc5508 processor, then I stumbled across this HDMI board problem. Sc5508s are still under the extended warranty, but I wondering if the problem has actually been addressed? Are Sc5508s that have had the hdmi boards replaced really fixed or are they probably going to fail again?

Thanks!

Well, I think I just joined the club. TX-SR707 - came home yesterday and no sound. Powered off the unit completely, then it worked for the rest of the evening. Came home tonight, no sound from any of the HDMI sources. The "MS Windows 101" trick of powering down did not do anything. Wondering if it is worth trying to get it repaired, or just upgrade.

If I do want to try the repair route, how does one contact Onkyo? I skimmed their site but all I saw was a support forum that looked pretty dead.

Thanks!

That doesn't apply to his model. His is a SR (non-network) receiver. Onkyo's extended coverage that you linked to is for network (NR) receivers. The reason for the extended coverage is due to a defective network chip that TI provided.

Appreciate the clarification...my apologies to all for the oversight.

I have an SR-706 purchased many years ago - 2008, if I recall correctly. I recently bought an Xbox One, and the receiver did not want to sync up the HDMI - I just kept getting a message saying there was nothing connected. I can get it working after multiple reboots of the Xbox and the receiver, but after reading this thread I'm wondering if it's not the reboots but just that screwing around with all that gives the receiver enough time to warm up.

Then the problems starting appearing on the other HDMI channels. My cable box, which has worked for years with this receiver without a glitch, is suddenly having problems with audio - the center channel goes out, the audio detection through HDMI picks the wrong audio type, etc. Also, sometimes now when I first switch to another HDMI source I get bars of noise that slowly crawl up the screen for maybe 10 seconds before the signal locks in.

I assume these are symptoms of impending failure of the HDMI board? If so, I think I'm going to retire this receiver and get a new one. I don't think it's worth sending out a receiver for repair that's 8 years old already.

Any suggestions for a replacement? Would the TX-NR656 be a replacement that would retain the same audio quality? It's significantly cheaper than the SR706 despite having many more features, but I'm hoping that this is just due to the march of technology and not a decrease in quality or sound. I don't care about THX certification, so long as the sound quality isn't impaired.

Any thoughts?

More people with woes..

I just got one tip, always power off the Onkyo when you are plugging HDMI cables..

My receiver has been working great with the repair,
I'm not using HDMI through the receiver at the moment, my mac is going straight to my screen and the onkyo is going to the second port of my screen.. I installed a bigger screen to watch a movie yesterday.. I unplugged my computer from the screen and hooked that up to the second screen, apparently this was enough to make the onkyo go haywire.. suddenly my remote wasn't working anymore, couldn't switch through the speaker sections (mono/stereo/all channel/pure audio etc..)
Had to reset the amp, then it started working again, of course then I had to do the setup all over again.

Depends what you mean by "audio" and "sound" quality...subjective or objective or both? Do you use and feel the "sound" quality you're describing is attributed to Audyssey? If so, as you're probably aware, Onkyo has replaced Audyssey with variations of AccuEQ. There are plenty of people on both sides of the Audyssey fence. Then there's the crisp, clear, powerful, dynamic sound that Onkyo owners are familiar with and generally attributed to Onkyo's historically beefier high current power supplies and amps. I can only speak to the 636 that I currently own in that it has the same sonic characteristics of my previous Onkyo AVRs (805 & 809). Hopefully, others with yours and more recent models can chime in and offer their experiences as well.

One other thought: AVS members in the Onkyo 800/900 threads are reporting their high satisfaction with these newer units. Additionally, the April 2016 edition of Sound & Vision rated the 900 as a Top Pick. No doubt, the 900 with its toroidal transformer delivers the sound qualities Onkyo is known for. It has an MSRP of $1599 but recent sales at Fry's of $847-$899 almost make it a "no brainer" for those who don't need greater than 7 channel capability. Good luck with your search!

Well I bought my Onkyo cause I really the sound quality from the receiver I borrowed for a few months from a friend.
can't recall the number though, Older Onkyo with a gray band in the middle on the faceplate.
Certainly the amp was bigger (longer) and a lot heavier than my NR717
It packed a bit more punch in wattage and I'd say it probably sounded a little bit better than the one I have now.
Probably due to the fact that I didn't have to crank it up as high to achieve full bodied sound in my room.
But overall the sound quality is the same.
And I'm sure there was a nice price difference between the two models I'm talking about.

As for Auddysey, well I like the Dynamic EQ, love that it again delivers more full bodied sound at lower volumes and not too harsh at high levels..
Don't like the auddysey on though.. that messes up the sound big time.. since I use it for monitor and mixing purposes. My control room is treated and pretty decent. So I'm not sure if what it seems to be correcting is useful to me. And playback without Auddyssey on sounds way more natural in the high frequencies.
If I'm mixing I even put the dynamic eq off, as well I don't want any processing going on which changes my equalising and level decisions.

I don't know if I'd recommend the brand though, sure they are nice receiver packed with way too many options for a nice price.
They do deliver a nice sound, but the internet is filled with tales and complaints of all kinds of models failing or exhibiting problems. And sure like mine with the faulty chip thing.. well that can't be good for their reputation, but they indeed fixed it up nicely in record time so lots of kudos to them there.
So just make sure you search for a model with the least complaints or an already fixed up amp if you go for one of the problem models.

Yeah features/price wise they are probably hard to beat?
The sound is good and clear, certainly compared to other home system amps.. when my Onkyo was in for repair, I used a kenwood amp a 70's one and a late 90's one.. now the 70's one sounded fun, but both were incredibly muffled in the highs and muddy in the low mids compared to the Onkyo, so they are doing something right.

I used to run a Urei/JBL 6290 for the stereo, now that also gave me a lot of power and clear sound, but at 600w per channel into 4 ohm.. I could easily blow my speakers with that one.. I now use one channel of it to power my sub.
And the Onkyo is perfectly suited for my main speakers which gives me a safer feeling

Has anyone had luck with Onkyo repairing a 906? Mine looks to have caught the failed board bug and I haven't been able to bring it back to life.

I haven't looked at the cap tactic yet, but figured I'd ask. I did enter my serial number on the Onkyo site and it told me it wasn't covered by the extended warranty.


Thanks!

Repairing a bad board will set you back $200-$300 while replacing the board will set you back about $600. Not sure if it is worth it. The HDMI board is 1.3 and the Audyssey is an outdated version. If you tried repairing the board, Onkyo will likely refuse to repair the same board opting to replace the board. If that does not work, they will probably claim that something you did might have damaged the unit and you can look at higher costs...

Onkyo TX NR-626 HDMI problem

Hi Jon,

I saw a previous post of yours re: replacing Caps on HDMI board with 105 deg. C caps.

Do you recall which component locations, or did you just replace every Cap? Is your fix still working (i.e., seems to have resolved the problem)?

I'm not against trying to replace the HDMI board (looks like it would be pretty straight forward), but wondering where to get? I checked Ebay, and saw only a used board for sale... Thanks for yours or anyone elses input...

IT's been a while since some of these problems have occurred, but will try to explain the background of my unit for others:

I have an Onkyo TX NR-626 that seems to have displayed the HDMI Problem. Purchased in Dec 2013. My unit had both a "Main Out" and a "Sub Out". The Main out HDMI lost video in about Feb 2013, so I switched to the Sub Out. Then the Sub Out had sound issues, with the sound dropping out periodically.

Took it to repair center in Apr 2014, that replaced the HDMI board.

Same sequence of problems occurred in about July-Aug 2015, and repaired again in about Dec 2015 (again replaced HDMI board).

In July 2016 (out of warranty), the Main HDMI out sound began dropping out again so I switched to Sub Out. Then a month or two later, the Sub Out HDMI video completely failed, so I switched back to main out (that was still experiencing sound drop out (i.e, I think the voice 'channel' would drop out?). I'm trying to recall exactly which sound settings I was using (i.e., Dolby, PLX II) but noticed that when I switched the sound mode to "All Channel Stereo" that I didn't experience (or at least notice?) the sound drop-out. The voice is more difficult to hear/distinguish on some movies (definitely different than the 'Movie' sound modes). I did check Onkyo's site where I entered my model no/ser no. and received a message that my receiver was not covered by their warranty extensions (though it sounds like it may be experiencing similar issues as the others).

My cabinet is open in front, closed in back with 1 or 1.5 inch clearance on right, 6" on left, and 6 inch on top. There are no vent holes on the sides of my Onkyo receiver, but rather, I believe just on the top (haven't checked the bottom). I was running one of the "laptop" cooling bases on the top of the unit (even with the irritating hum) plugged into the Onkyo USB port since about July 2016. Unit has remained "stable" since then, but not sure if because of the cooling...

So, asking above questions with the chance that I may be able to repair it.

I had a couple of 905s and a 906... I had gotten rid of them a while ago... The problem was that the Onkyo used 85 degree caps and the fix is to replace them with 105 degree caps. You have to replace all of the 85 degree ones.

FWIW, Onkyo repaired my TX-SR707 at no cost to me, including shipping it there and back. Of course, in the meantime I sort of fell into a deal on a newer Denon receiver and bought that (no self control at all...), so the 707 is just gathering dust. I did test it when I got it back and it works perfectly. I just tossed it up on the Classifieds, if anyone is interested. No reasonable offer refused

Is there a list of needed caps somewhere?My refurbished 3007 died again, I'm using it to power various speakers and zones throughout the house, I'm not using it for video anymore but I may try to replace the caps and see if I can't get it running again, for SnG if nothing else.
