I can replace Q5702 but I don't have a 100V/100uF capacitor unless I pull it from the other board.

Well isn't that just something. That is the same problem Nash was just dealing with for the pre B- line.
Q5702= KSA992FTA
C5708= 100uf/100v
R5704= 100ohm/1watt
R5703= 4.7ohm/1watt

R5703 is bad, r5704 is good

ok, so replacement of 3 parts required. Where were we at with this one? I did not read back.

Sr channel blown, next step was to jumper two relay points and power on to test cn501 as ground. Outputs are currently desoldered fron q5405 and q5406

You can leave jumper if you wish. The display will still power off if there is a problem.

I have to run some errands but I'll put it back together and power it on in an hour.

Put everything back together and partial success. Everything powers on, but I'm only getting audio no HDMI. I tried the tuner (audio, woohoo) and a blu-ray player (no audio or video). This board experienced the same symptoms when I swapped it into the other unit, audio but no HDMI.
Swapped the HDMI board from the other AVR, no audio or HDMI, but this time I tried composite video and that worked.

So lets clarify here. I need to understand clearly. All speakers outputs work properly, correct. All audio inputs work except HDMI, correct? HDMI video out does not work but composite video out does, correct?

Let's see.
The HDMI board that's in there now is from the other unit.
It currently get composite video, but no HDMI video, and no sound at all from HDMI or the tuner. I have not tried any other analog inputs.
The HDMI board that was in there originally, I get audio from the tuner but that's it. I tried it with a blu-ray player and got neither video no audio from HDMI.
I only tested one of the speaker outputs (Front Left I believe).
What would you like me to test/confirm?

Ok, this is where I am a little confused. I thought you said you tried the HDMI of the non working unit in the working unit. Do either or both HDMI boards work properly in the good receiver?

Neither board gives HDMI (Video or audio), so no, neither board works properly.
The only thing I got out of one board was audio from the FM tuner.
The other board all I got out of it was composite video (but I only tested one board for composite video).
If you'd like I can test all speaker outputs (except SR since the outputs are currently desoldered on that channel).
I can also put the other HDMI board back in and check composite video.
I did not check either board for analog audio (red/white).

So both HDMI boards were tested in both receivers?
