Give me till Monday so I can respond at work on those pics. I'm packing for a move that starts in less than 1 week. Heh.. And the place I work for is considering a move too.

This fix should last a lot longer than the original amount of time you got before hdmi troubles... No guarantees however.

Getting a nice long service life for a receiver however... I can not say.

Auxiliary cooling would only delay the inevitable in my opinion. However. If the amp is in a rather poorly ventilated area then some sort of fan would undoubtedly help.

Default My 606 FIXED!!!!

I was one of the lucky ones. Since my 606 was under warranty, I dropped it at a local servicer here in Dallas. They had it just under 4 days and I hooked it all back up last night. Works beautifully.

They just replaced some caps and added 4 more I think he said.

Hope it lasts.

Thanks all.

I still have had no problems with my 606. Did I possibly get one of the good batches?

Some PCBs came with a different manufacturer of regulator. They tend to be more reliable.

I tried uploading them as attachments but resolution is diminished. Lets see if this will be helpful or if I need to do a bunch of emails. I'm in the middle of a move so I don't have much time for the net right now.

Electrolytics are 100uf 4v - the little cans with the sharpy dots on them.

Added caps are thin film 1uf 50v - the red chicklets on top of the regulators.

and remember.. no matter how good a job you do this will only fix about 66% to 75% of units with hdmi problems.
Oh and take a look at those regulators before you start.. if they have a 480xx number then try it. if they have a BAxxx number then this prolly wont help.
I'm doing this from memory so sorry for any slight errors.

So i accidentally got polarized 1uf caps, anyone know which way these should be added to the top of the regulators?

Update on my hdmi board. I replaced all the 100uf caps, but wasn't able to get the 1uf caps to solder to the board. (I am very inexperienced). I thought I would try it out with the new caps in. Well...it didn't work.....everything is the same. All HDMI works but no OSD and no out from component inputs on HDMI. It does seem to be able to display HD picture faster (use to have to let it warm up) I will be able to verify that tomorrow.

Couple questions, will adding the 1uf caps have the possibility of fixing the OSD, etc. or should I just assume that something else is wrong. Also if adding those has a chance on fixing the problems, any tips on getting them to solder to the tab of the regulator. I tried for about an hour on all of them with no luck. Couldn't get the solder to stick to the tabs. (just an fyi, I am using a 60w iron).

Thanks

Yes... there is a better than 50 50 chance that 1uf non polorized thin film caps on the regulators specified will fix it. FYI a little solder rosin may get the solder to flow more easily. But if you need more than 5 or 7 seconds to get that regulator tab to accept solder cleanly then you have a problem. Not enough iron or dirty tip or something. To much heat, to long under heat, will hurt semiconductors.
You can damage a board that costs like 265 bux from Onkyo. be careful

Thx for the pics.
It may help.
Since last time I discovered that we have a new law in Sweden that we can claim products up to three years for manufacturing fault. (Not a warranty).
I calimed the fault and my 606 is with Onkyos service now.
I would know in a couple of weeks if they accepted the repair.
The guy at the store I bought the 606 with said it wasn't the first one he sent back.

I noticed in your pics that the all regulators next to the 100uf caps that need to be replaced have the 1uf film caps on them except one, would there be any benefit to adding a one to it as well?

Never had to. Onkyo doesn't claim this one is an issue but once in a rare while I have found a new cap on that regulator will stabilize hdmi operation. I have never found an issue however that could be resolved by adding a tf cap there as well. Onkyo's bulletin does not even cover that one iirc. Just 4 100uf and 4 .1uf or 1uf tf cap depending on what onkyo ends up sending us. heh

OK I was just wondering, I had 5 of the film caps and didn't know if i needed to throw one on it.

Default Another TX-SR606 victim

Hi - I'm hoping for some advice from some of you experts; my problem is similar but very strange:

I've had the 606 since Dec 2008 with minimal issues - sometimes I would have to switch back 'n forth a few times to get the audio to work - not a big deal. However suddenly I have a major problem with the HDMI video out: the picture is very grainy with a green background, even on the Onkyo setup screen! I can still see the true picture, but it's grainy and green regardless of the source input.

I have this hooked up to an Optoma projector with HDMI to DVI adapter, so my first suspect was the adapter. Bought a new one, but problem remains. If I run my blu-ray or cable box directly to the projector, picture is perfect (even with the original adapter).

Now here's the kicker - I hooked the 606 up to my Sharp Aquos LCD TV in another room and everything is perfect!!! Back to the projector and it's green/grainy again. I'm afraid if I bring the 606 into a service center, they're going to tell me it works fine. Plus I lost my receipt.

In summary, everything works individually, but the desired combination stopped working after 20 months of working fine. Any ideas on this bizarre situation?

1 Thing you can try if you have not already... Switch the HDMI setting to video passthrough and see if that helps.
