Check the 900V with a 1KV meter !!. Probably the G-2 are at
abt 400V. Normaly a strong jug will quickly give you the line.
Also look at all the CRT voltages to be sure they are OK.
It may turn out to be all the same cause.

Good advice. I'd like to add that there are sneaky ways to do it with sub-1KV meters. On some tube era sets the lower supply rail is 300-350V. I've (when I've lacked a 1KV meter) measured that 350V with respect to ground, recorded it, then measured the 900V rail with respect to the 350V rail (only a 550V difference), then added the two numbers...It's crude but it works in a pinch.
