Cool Repairing Onkyo HTR667 aka 606

The rules says I need to post 5 times before I can paste links. I will update this when I have more then five with the solution.
Now I can post links...

I have had this receiver for 2.5 years. The first year the receiver was sent to a Onkyo Authorized repair because all the HDMI stop functioning. The following happened over a year, after the first repair, with the last happening a couple of weeks ago:

Problem:
First. 1080p went out on the Playstation 3, had to use 1080i or lower.
Second. The HTR667 Started needed a warm up period for HDMI and Component to work.
Third. Component eventually stop working. Along with OSD. Checked online, you can no longer extend warranty for this receiver. 2 months out of warrenty.

Searched the net:
Countless reads later I found the following threads:
Onkyo TX-SR606 HDMI Switching headache
http://www./avs-vb/showthread.php?p=...2#post19406942

Decided to follow what spldart recommended, due to him working on these receivers significantly.

Solution:
Ordered the following off of Digikey.com
1. CAP CER 1UF 50V Y5V RAD
445-2865-ND FK24Y5V1H105Z 0.18900x10 $1.89 (you only need 4)
2. CAP 100UF 4V HB ELECT SMD
PCE3024CT-ND EEV-HB0G101R 0.53000x5 $2.65

3. 2 24oz cans of beer (you need this to work on SMD or microminiature components because they are a pain in the rectum. I see why CZ recommended hole fed components).

After about an 1 1/2 hours, I can gladly say that everything works.
Here are pictures for your viewing enjoyment.

Back:
-Highlighted Blue - Use 1uf 50V Cer Caps
-Highlighted Red - Use 100uf 4V SMD Caps
Before:

After:






Front:

Works like a charm 66% to 70% of the time.... but the fix seems permanent once it works.

I followed the instructions and it fixed the hdmi problem, but now I got no sound from 606. Does anybody know what would cause that?

Your dsp processor and it's ram and eeprom are on the same board. If you fixed your hdmi problem with the cap fix but you lost sound (lemme guess... direct and pure sound modes work) you have somehow effected your dsp operation. Look for solder blobs or something simlilar.

Not even direct? Non sequitor... does not compute.

a 606, 960, 667, 5.9 doesn't even need a u41/u44 to do direct audio... That's handled by Q5501 which does e-vol and analog select duties.... On main pcb

I think I shorted a part of the circuits and the amp is shutting off the output to protect itself or something. My hunch is that something simple will fix the problem, but I am not going to find it so will end up buying a new amp. Maybe I did it on purpose to buy a new one?

The amp is shutting down and flashing it's standby light? I would definitely suspect a wire clipping or blob of solder got on the main board.
If the unit will stay on I would press (with power on) display (and hold) then power, then release both... You should now be looking at the main firmware revision... If you quickly use the tone + button you can toggle through dsp firmware and VD (video) firmware.
If any reports ???????????? then that relevant circuits processor is non responsive. If you had done this before your repair then you would have seen Vd ????????? after two presses of tone + after the dispay power sequence.
i wonder if your dsp is currently reporting ????????????????
