They specified it was just the faulty parts, and not the entire board, but that the problematic parts had been identified and entirely new/different parts (the capacitors) were now being sent out. That was as of March.

Replacing the capacitors was originally only a short term fix because they didn't realize the capacitors they were putting back on would eventually fail as well. That has supposedly been rectified.
That is my main concern, and I hope what they're saying is in fact true.

I called the repair center (which should be receiving my Onkyo 667 today) and asked "are you just going to be replacing the bad parts with the same faulty parts?" and he said "no, these are new/updated components".

I'm not excited about doing without my receiver for a month (or two), but I'm willing to do wait however long it takes for them to fix the problem permanently. Other than this glaring issue, I've been more than happy with my Onkyo.

*crossing fingers*

Another victim of the issue here. My TX-SR606 has been progressively getting worse over the last six months, and now has to be power cycled 5+ times when cold-powering on or switching inputs to get it to work. I purchased it in July 2008 from Amazon.

I emailed Onkyo today, hoping for warranty repair before my warranty period runs out.

Anyone have any experience they'd like to share with repair shops in North Carolina (Lenior and Charlotte are listed on Onkyo's website)?

My Onkyo HT-R667 just arrived at the Charlotte shop (Carphonics) yesterday. I called and spoke to both them and the one in Lenoir, NC (Pro Connect). The guy I spoke to from Lenoir was very nice, but he told me he would only work on Onkyo's if I had a way to drop it off and pick it up. He said he'd had too many problems with shipping and receiving Onkyo's. But he was familiar with the problem we're having.

Then I called the one in Charlotte, the guy wasn't quite as warm and inviting as the guy in Lenoir, but at least he said they'd be happy to work on it. Both places told me that Onkyo's current tech note for the procedure for fixing the Onkyos were to first replace the capacitors with new/updated components and if that didn't work the hdmi board would be replaced. I asked him what the turnaround time would be and he said "depends.. if the cap replacement works then just about a week or so, but if we have to order a board it will be longer... several weeks." But I specifically asked "are they telling you to replace the faulty parts with the same part that will eventually fail?" and he said "no, these are updated parts."

The next day I called back to the one in Lenoir because I was going to be driving through NC soon and while it would be somewhat out of my way, I was considering dropping it off to them. The guy I spoke to this time didn't impress me so much. He may have just been a service clerk and not a technician, but he told me that they were "trying to move away from hdmi" and that all I had to do to avoid this problem was to run my hdmi cable from my component straight to the tv.. uhh...yeah, but...

Therefore, I shipped to Charlotte and got confirmation of delivery yesterday. So, we'll see. I'm trying to be optimistic and hope for the best.

Quick update. As of a few days ago those .1uf 50 volt caps that were added to the board after the fact to stabilize the regulators are now being replaced by 1uf 50 volt caps.

They didn't update the bulletin. Just started shipping the new larger value when you order the part number listed in the bulletin. In my opinion the only reason for this is the engineers decided that the increased value would create further stability and get more boards back in operation for a longer time. I would agree with this thought process if it is indeed the case. I've stocked quite a few.

So what does this mean to us dummies?

I don't really know what the difference is between .1uf and 1uf other than 1 is greater than .1. But what I think you said was that when the repair shop goes to replace the parts that are in the bulletin they use what they are sent, and you are saying they didn't update the tech note, just sending beefier parts. What if the repair shop uses what they've got in stock and not the new, beefier ones Onkyo's sending out?

I just don't want to have to ship my receiver to the repair shop again and again.

Dunno yet. I haven't done enough boards with the new value to know if they will have a higher success rate or more durability. I figure onkyo is just gonna let the service centers run out of the .1's and the switch to the 1s

Hi, I managed to fix my 606 by replacing all the 100uf caps.
Just read your post and now I'm a little curious about where on the hdmi board those 1uf caps you mentioned are supposed to be soldered. I am getting a little worried that my repair won't last that long.
It would be really nice of you if you could upload a picture or describe where to add these components.

I'll try to remember to bring my pics of a finished hdmi board on a 606 home with me tomorrow. I use it as a quick reference. Maybe upload them on flickr and paste them here. keep in mind though that I've been very busy so be patient.
And yes.. Your 100uf 4v caps can often get the board going again but it wont last. As soon as the heat and strain (for lack of better words) from those regulators hit the caps they start gaining esr (doesn't take much) and then the problem comes back. Generally takes a few months but sometimes less.
I assume you used the same type surface mount electrolytic caps.?
Anywho. A few days of use with the new caps are very unlikely to be a problem at all and when you add the 1uf ones you wont need to worry about re replacing the 100uf's

Thanks, I would really appreciate it! Actually I did what this guide suggested w w w.avsforum.c o m/avs-vb/showthread.php?t=1246078 and replaced all the smd caps with some 100uf axial electrolytic 16v and 105 degree ones. It doesn't look as nice as the original board but they're easier to work with. I guess it shouldn't matter if I use 16v or 10v caps since both are rated a minimum throughput of 6,3v. The work was done 5 days ago but I haven't been using the unit that much since then. It's still working fine so I'm going with what you're saying and hope there won't be any issues after adding the 1uf capacitors.

Hey! add me to the list of victims...My HDMI works great to the Tivo and to the Bluray player, but lost xbox360 and (of course) the Wii. I used to do all of the voodoo rituals to get them to work, but it got worse and won't even display these...

Mine is under warranty until Sept, so I'll need to send it to Dtr Technologies in Colorado.

Any body have any tips for dealing with the Colorado service center?

Thanks for the detailed info.

I just got off the phone with Steve at Carphonics and he seemed helpful, yet a little short with me. It looks like I'll be driving it down myself to drop it off at his shop for repair in the next few days since I'm really nervous about shipping it. I'll post again about my experience.

Thanks a lot spldart!
I assume the added caps are the ones sitting on top of those transistors. I got a couple of questions if you don't mind.

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?

I just brought mine home from the ONKYO service tech. Essentially, the power supply to the HDMI board is rated way too low. He told me the caps were rated at 3.3v and he replaced them with 4.4v (I think he said 4.4). He replaced the whole board/power supply and everything is working 100% now.

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.
