Yep, that's the problem I'm having. Had color (with stretched out and fuzzy images) before I did a full cap kit, but after the cap kit, I have the grey screen -- even though the picture is now sharp and proportioned correctly. (see attached pics)
I found a few old mentions from Ken Layton (here on KLoV) that the resistor is a half-watt, 100k resistor, so that's what I installed. It made ZERO difference in the picture quality.
