How to DIY ; TX-SR576/TX-SR606/etc HDMI daughterboard repair (for dummies?) - Page 3

CZ_the_DAY: Thanks for the info and to let you that on a HT-R667 this fix works, will go back in to replace the other caps to hopefully restore the OSD but for now all the hdmi switching works like a dream...

This may prove useful, my HT-S6100 Receiver (R667, similar to 606?) is beginning to malfunction after 1.5 years of usage

I know how to do many things related to electronics, but haven't really ever soldered anything before. How hard of a task is it to solder these caps on? Glad I found this thread before buying a new receiver

Hey new here, just want to say a big thanks for all the info shared on here, I managed to fix my 606 (in a rather unothordox fashion lol) which crapped out on me as I bought a new TV so all is well now!!

Thanks for posting this. I've been having handshake issues for about a year on my 606 but wouldn't send it in as I don't have speakers on my tv. The handshake issues got so bad tat I would just leave the receiver on 24/7. Lately I began losing sync at random intervals.

Since I couldn't send the receiver in I was about to buy a new one (different brand) but saw this. Figured it was worth a shot. Anyway, the first time I powered it on after replacing the four caps I didn't see any sync issues. Only been a couple hours but I think my issues were fixed.

Ok folks, new here, and reading all the 606 hdmi info I can get, so now I'm pretty much mush in the brain department. So for a little clarification, do you only need to replace the 4 caps or do what spldart did and replace them all plus add the little red one across the grd and v. out pins also...sorry not real technical in describing this....

as I read some saying the 4 caps replacement fixed the prob and if so then what is the purpose of the red ones bridging across the other ic's or caps or whatever they are....

Gentlemen,

I am happy to report that I am another satisfied customer. My 606 was having terrible handshake issues for quite some time. Today I replaced the 4 caps mentioned and handshaking is now within 3 seconds.

As an aside, this did not fix the OSD issue. I read back to CZ's earlier post about replacing other units and also replaced C8162 & C278. This did not resolve the OSD issue either. I had to stop there as I was out of replacement units. (FYI - I used 16V caps)

Does anybody know definitively which caps are responsible for the OSD?

A great thanks goes out to all who have contributed to this solution!

Many thanks to all. Between this thread and the one at High Def Forum, and $10 worth of parts, my 606 is back in action.

Would anyone know where we might be able to pull 12v DC so a PC fan could be added without the use of an external power supply, since my 606's HDMI board is already fully populated?

CZ_the_DAY: Thanks for this post.

I am from Russia.

I have Onkyo 576 revicer about 2 years. Riciever had this HDMI issues 6 month.

I change caps with tantalum smd 10v 100uf 85C. And I don't see a problem.

Thank you.

In next post will be photos of the HDMI board.

I also proceeded to replace capacitors and add some more to the regulators as advised by onkyo (with a lot of help from a friend, actually) and everything seems to be in order once again.

Thank you very much! I didn't have the money to buy a new receiver and I should sent it overseas to use the warranty. An expensive alternative also.

The question is:
Couldn't we use the main power converter for powering the fan(/s) directly from there?
(I am talking about conversion because I live in Europe and AC to DC converters are in use)
Wouldn't that be safer that messing around with the boards?

I see that there is not a combination to result 12 volts exactly, but I guess that it can be arranged more easily than powering from the HDMI daughterboard.

What are your thoughts about it?

Yes! That is what I am writing about.
I just do not know if the transformer is region independent or altered.

I really have to give a major thank you to the guys that have done the legwork in this and other forums. Thanks to you guys, I now have a working 606 again. Now I just need to figure out how to make that case fan happen and all will be good.

Hi Everyone,

What a post, super info from Thread Starter.

I have an 805 in which the HDMI ports died earlier this week (no picture), have ruled out the cable and source and am absolutely sure it is the 805.

Was wondering if anyone has tried this procedure with the 805 and if so did it work (TX-SR805, complete model number).

If not, does anyone know where I can buy an HDMI board for my 805? I know they are expensive but I would like to fix my 805. Neither Onkyo nor their Authorized Service Center will sell me the board direct. I have to ship my 50 pound beast to and from the service center, pay their labor and parts, plus sales tax then it would cost me over $500. I think I have the skill to just replace the board myself if I could find a source to buy one. Please let me know it you can on where I could buy a board. Thank you so much everyone.

Fantastic thread and thanks for sharing your experience Thread Starter.

Hi CZ,

Thanks for chiming in, hoped that you would. You are right, mine did start going out gradually. What would happen, I would lose the picture to what I call video noise (white, fuzzy screen). I would then unplug the hdmi cable and re-plug it back back in, the picture would come back on. This went on for about 3 months before it finally would not come back on at all.

If you would be willing to repair my board like you did yours I would gladly pay you for your time and of course for the parts. If you can't do that do you possibly know someone who might repair it? Any help or advice that you could give me would be greatly, I mean GREATLY, appreciated. Thanks CZ and have a wonderful weekend.

Hi Cz,

Would you know if this cap repair would also address intermittant static noise from speakers on a 1007?

I am, out of warranty and my right surround back speaker has intermittant static like noise. If I play with the surround settings and shut off the surround backs (7.1) the noise jumps to the right surround speaker 5.1.

This happens in all input types - analog, coax digital and HDMI.

Thanks

Tom

I've got a 576. Here's my story...

I just stepped up to a 1080p display. Prior, I've only ever had 720p/1080i flowing through the 576. So I didn't think I'd have any issue when I plugged in my new 1080p VT25.

Trying to feed 1080p from my Core i3 HTPC or PS3 causes the 576 to fail. The "HDMI" icon blinks about 5 seconds. Then it says "No Signal". My screen doesn't even flicker. Just black.

But anything less than 1080p... no problems.

Wondering if this is in the same vein as the problem y'all have been having.

Too late for me to warranty repair. Been almost 3 years. Time for an upgrade. Is it safe to get an 8 series Onkyo?

I suspect, that this is another problem in combination with you display.

I might be being too careful, but I can't remove the daughterboard from the three white connectors, it seems really tight, any special tips?

Well... that's what I was hoping... would've been an easier explanation and fix. I was hoping someone out there with the VT25 would've already run into this problem with the 576--that it was just a software problem and getting the settings right. At this point, without a warranty, I'm basically committing myself to an upgrade. Maybe a 608 or a 708. I'd rather not until I've fleshed everything out.

Let's face it... we all know the 576... there aren't -that many- settings in the 576 (or the VT25) that end-users can manipulate to screw up 1080(p) HDMI passthru/switching. Even if I were a noob.

I've gone through all the settings and HDMI input assignments. And all the resets in the world haven't fixed it.

Simply put, when I directly HDMI plug-in my 1080(p) sources (Panny 3D BD player, PS3, Core i3) into the VT25, I have NO problems. (So at a minimum, I think we can't blame my eBay and Monoprice HDMI cables.) ***You put the 576 in between, I can ONLY switch 1080(i) and below***

Because I've never had to put my 576 up to the task of 1080(p) switching, I don't know if (1) it was ever able to switch 1080(p) or if (2) it previously was capable at 1080(p) and more recently failed.

@CZ

I don't quite figure how covering the vents is going to help troubleshoot the 1080p vs 1080i switching. Wouldn't that just cause a catastrophic failure!? It's not like I've got a backup!

Welp... I crossed my fingers and was hoping you were on to something. So just to be thorough, I re-tried all the HDMI cables, directly to the TV.

Core i3 directly into to the TV. In 1080p. No problems.

Using the same cables... Panny 3D BD directly into to the TV. In 1080p. Ice Age FULL 3D. No problems.

(BTW, 3D works -perfect- with HDMI 1.3 cables AFAICT with audio and video--can't speak for audio return channel or ethernet.)

Then I put the 576 in the mix. 576 insists that there's "No Signal". Screen is black... no sound. Not even static.

So I don't think the cables are a problem. And having ruled out a problem with any of my other hardware... And with all the people reporting various manifestations of HDMI problems with 576s and 606s, it's got to be the receiver.

As far as the cold start theory, I can tell you that my receiver is on all day long. And it's in a fairly enclosed media cabinet, so it's pretty much hot all the time. Definitely fully warmed up by the time I get to troubleshoot it. If anything... overly hot.

Of note... as I speak, my wife is watching Gossip Girl 1080i off my PVR and it's starting to show some bizzare artifacts--albeit intermittent and rarely. Strange greenish lines I've not seen before. Mind you, the PVR is 1080i... never 1080p.

I'll bet that I've pushed the 576 to death with the heat, that this is the beginning of the death knell. My 1080i is starting to go maybe?

I don't think there's a definitive way to tell unless I take it to the shop. But there's no way I'm going to pay to diagnose/repair this rig professionally. I think I only paid about $200 for it in the first place.

I think I'm going to take the dive and just pick up an RC260. Some decent upgrades. And there's some great deals on pre-owned units on Amazon.

If anyone wants to experiment with an orphaned 576 that doesn't seem to switch/pass 1080p... swing by Hoboken, NJ and I'll let you have it after I get my new receiver.
