OK well done so far.
Good news is Sams has the manual ( redrawn neatly ). Bad news is
I dont have it. New scan of schematic better but I still cant read.
At this point either they are taking the color off before this point or
you have a color problem. If you have a VCR, game or generator
with RF out it will narrow that down.
IIRC I had a similar set with no color & it was a low ohm ( 1 or 2 ohm )
resistor feeding B+ to an IC. Look into that. Maybe someone on the list
can post the Sams, its MUCH easier to follow. Its # 2640-1

I know that when i feed it RF from my snes, or via an rf modulator, i get full color video. worse comes to worse, i'll just shove a modulator inside.

If you got a scope look at the video on Q101 emitter & compare
between RF input & direct. All I can think of is its not big enough.
Otherwise you got me on this one.
