Changing the resistors did make a marginal improvement, but there is still a snowy picture.
I am guessing the RF amp is still weak. When checking voltage there it was still too low.
Should have 130v and was 107v
I then looked at the main 130v line, it TOO was low.
109v
that comes via the bleeder resistor (1.36k) from the 275v which is ay about 265v once things warm up.( close enough.
That bleeder is still getting quite warm :/
IT checks OK resistance wise, but that does not mean anything :/
gonna have to replace it.

It calls for a 17w part
closest I could find was 1.3 kOhms at 25 w

Hopefully this will get the voltage in the right area
anyway, here is how it looks with direct video input
