The ones I replaced were on the down converter board - the one that sits vertically off to the side and perpendicular to the logic board. I couldn't inspect the capacitors until I had removed the digital assembly.

I swapped that with a known good one with no change in behavior.
I suspect the problem's on the analog board itself. I just don't know what the problem is!

I'm not opposed to making component level repairs, but I'm not opposed to replacing the whole board, either.

I'm still gathering up advice here so I can figure things out. I'm pretty much stumped.
