when it comes to bias "close" does not cut it, need to know exactly, a 20v swing high on the K and low on the G1 will cut off the CRT completely.
by bet is the video out either a weak tube or a defect in the circuits around it. But that is a guess with out voltage checks you are just blindly subbing and replacing parts.
once you narrow down by voltage checks of the CRT pins you can address the fault area.
