What type of capacitor is that? They look like some kind of ceramic multilayer ones. If they are polarized, is the negative leg soldered to the transistor base?
The added ones are the ones sitting on top of those Toshiba regulators

Those are thin film caps. And they are non-polarized.

Edit: I pwn page 6

The tech pointed to his bench and there were SIX other 606's he was working on for the same problem! This is a problem with the 606 and apparently not the other models in the line. Mine was under warranty and I had my receipt, so it cost me nothing.
You have either been given some incorrect info or relayed that info inaccurately. The 100uf's both original and replacement are 4 volt and the add on caps whether .1uf or 1 uf are both 50 volt. And the power supply isn't underrated but simply becomes unstable without enough cap to keep the regulators from oscillating. It was an engineering/design error and is correctable by the bulletin.
And that very same board is in 1 other onkyo model and one other integra model. Not just the 606.
And a similar problem has cropped up in a next gen model. BEFORE they figured out the problem with the 3 models from teh previous year. I doubt onkyo will have this problem again for a while... Lesson learned i imagine.
And yes. I know I'm overly simply stating the problem.

No biggie. I've noticed a lot of shops are terrible with accuracy or honesty.
/me hates that :~(
I've run out to the customer area of our shop occasionally to correct my manager in relaying the facts in a repair more than a few times

BTW... At the peak of this situation I had nearly 2 dozen U41 hdmi pcb situations sitting on my shelf at the same time :-/
I think the situation is 'in hand' now by onkyo. It was a bit of a runaway situation a while ago. But I can quote situations by nearly every major manufacture in the last 10 years that mirror this so don't be to judgmental.

Default Onkyo TX-606 HDMI Switching

I am experiencing the same problem several others have posted about - difficulty getting the HDMI handshake process to successfully complete. I've had my receiver for about 1.5 years. The problem began appearing about 6 months ago. It appears that something in the receiver is beginning to fail.

Same problem here. Could you post these images again?

I'm going to open my SR606 and, if I can, I would prefer to fix everything in a single step.

Thanks in advance.

Carphonics in Charlotte received my package last Thursday. When I spoke to them last Wednesday, they told me the backlog for repairs was only 1-2 days. Today when I called to confirm they received my package, they tell me the backlog is "at least 12-14 days" and that they haven't even looked at shipments and couldn't confirm receipt of my receiver (I have a signature-confirmed tracking number). Their shotty reputation is certainly holding true so far. The guy (same guy always answers the phone & says he's the owner) was rude, too.

Just fyi... thanks to AWOL on this forum I was able to find a place local in Dallas to fix what seems to be the same HDMI board problem as many of you are experiencing. Will try to update the amount of time it takes to get back and the quality of repair.

thanks everyone for the community of info.

How do you feel these new parts will last for the unit in the long run? Should we expect the unit to go on to live a normal, healthy life now or might it fail again in another year or year and a half?

Also, how important do you think it is to buy some type of auxiliary cooling solution to prolong the life of this unit? Will it make any difference?

Default Replaceing caps

Spldart, Finally I found someone that seems to solved this.
My 606 may have faild before but yesterday I got a new HD proj and a BD-player.
First time I tried to hook everything up though HDMI and the result, expecting a picture to blow me away, was a "bad analogue TV reception".
I quickly learned this was a fairly common problem and since I'm out of waranty I need to fix this myself.
So, as some other allready asked you I would really appriciate if you could send me these pictures also.
And, yes, I can solder.
Thanks for spending time helping us with this amp.
