Re-read entire thread so as to not miss anything when I get my unit in my hands (please, my Onkyo) and found this nugget from spldart which may concern you...

BE CAREFUL.
Maybe get your "Professional" to have a look there ?

I checked all of the solder joints and did my best to reseat the lifted tab (not completely broke off). When I put everything back together, I can no longer power the unit on as it immediately trips. In the process, I completely trashed the 5 wire connector going to the HDMI board.

I'm ready to drop-kick the unit in the 4 ft of snow we have recv'd the last week (it will be completely buried with the 1-2 ft we're expecting this week). I'm not ready to buy another receiver, especially when Onyko keeps coming up with the best ratings.

Any thoughts as to why the unit keeps tripping now? Can I buy just the HDMI mother board? Or should I offer it the unit to mother nature?
One more for you. This may or may not be the same symptoms your experiencing but...

From another thread...

I replaced all ten 100uF caps and added the four "jumper" caps for good measure. I've been soldering for many years and everything seemed to go well until I plugged the unit in.

When I plug it in I get the standby light, but when I push the power button, I get nothing but clicking. The relay clicking is the one on the power board. I can't see any stray bits of solder, or wire anywhere in the unit.

What... the.... heck... did... I... do....?
And then later on...

Good luck.

Mike- You are the MAN!!!! Sure enough, the fuse on the small board attached to the transformer is blown! I'll give it a shot tomorrow! Stay tuned!

Cool. I'm just hoping spldart takes pity on me and shows me some love in regards to the contents of the 886 bulletin since I'm out of warranty. Shameless, I know

Post back how you make out.

No luck, Mike. Replaced fuse and no I get absolutely nothing. Even offered some blood when I sliced open my finger on the housing. I'm done- it's going in the trash. Any recommendations on a replacement?

Default TX-SR607 similar issue: OSD disappears, component does not work.

I have had a similar problem with my TX-SR607 since day one. The OSD only worked for about 2 hours and then it was gone forever. Problem is I bought my unit in the US but live in Brazil and the warranty is void because it travelled overseas. Local authorized Onky service center wants to charge 1000 US dollar to replace HDMI board. Do you think replacing the capacitors will fix the issue with my 607?

The current official fix is to replace 5 100uf 4v sm caps and add 4 .1uf tf caps. I also tend to replace yet one more cap... A 22uf 4v sm cap as well. If this doesn't correct the hdmi issues then one can generally assume the unstable operation damaged one of the sensitive ic's on the board and the repair will be much more involved.
Just fyi

Edit.... This board is in another onkyo model and 1 integra model of the same year.
And a similar problem has cropped up in a couple models of the next year. (diff hdmi board.)
And I happen to use an onkyo in my home theater. Not everything they make is, well.. having issues.

Sorry to hear, bro. Wanna buy my Outlaw 990 ? Lol. Do you have the exact same symptoms ? Don't give up yet. Maybe spldart will make another appearance and hit you with a gem to help you out.

Ship it back to the USA and send it for warranty repair from there, assuming you know someone there... I would certainly try the repair, you stand a decent chance of repairing the unit should you do the repair correctly.

And why should they be charging so much money when the bulletin clearly states to replace capacitors and ONLY replace the board should the initial repair fail ? That is with the 606 anyway and I'd assume the same for the 607.

Thanks.
You might have to give me a day or three for one of these types to cross my bench.... I wont post confidential onkyo 'actual' stuff. But I'm willing to post me doin one of their boards... I believe I got one of your type hdmi boards coming up sometime soon. IIRC You need 11 chip type caps... your upgrading these tiny chip caps from .1 to 1 uf. What's effected is the reon ic comunication to some memory or maybe it was buffer ic's... I can't remember off the top of my head exactly... These caps are 'tweezers' kind of tiny.

And these flaky chip-caps present the same symptoms as the 606, right ? Good, very good. Now I just have to google how to shrink myself like Rick Moranis lol. Eagerly awaiting any further info, pics etc...

By chance, does this version of daughterboard have a protrusion or shark "fin" on the side opposite the HDMI connectors ?

Thanks Mike. I have thought about shipping it to my close friend in the US, but the shipping costs alone are way too expensive. Can you tell me if the 607's hdmi board similar to the 606's? Again, the OSD stopped working and the composite and component inputs don't work. Do you think that the problem will be fixed by replacing the capacitors?

I DO think replacing the capacitors and adding the new ones across the regulators will work because it sounds like your symptoms are the same as others who have fixed theirs this way. As in life nothing is gauranteed but if it's not working now what have u got to lose ?? No idea about the difference(s) between those two boards though... Maybe spldart will chime in for you.

spldart, is the 607's board similar to the 606's? I will most likely try to fix it myself because most service centers here in Brazil are either uninformed or dishonest. Also, electronics in general cost at least twice as much in Brazil as they do in the USA because of taxes and logistics costs.

the 607, as one would would expect, is a different design with more modern ic's.... But there is one regulator you want to do the mod to........ Just the one. And that's under certain circumstances... I'll hafta wait for the next 607 to cross my bench and take pics to post that too i guess.
Till then please wait patiently.. During the xmas season I'm TOTALLY SWAMPED and have little time to be mr helpful anywhere. hehe
