Are you getting replacements for R208 and 209 too? Those are the main culprit.

Looks like R208 and R209 are bad. Pull them out of circuit, test them (should be 6.8k) and if bad replace them.
While you're at it, check also R210, R211 and R212 (all 2.7k). No need to desolder them, just test them with neckboard unplugged from tube.
I can't see if you replaced C204. If not, do it.
turn the Screen pot down on the flyback.
if you have no brightness adjustment there then I would suspect cold solder at the G2 pin.
lol @ resistor replacements. you would've been better off sending this to Buffett.
I don't mean to be a condescending prick about this, but seriously send it to Buffett or Arcadecup.
it's obvious there's much deeper issues than you can probably fix yourself. I think it's awesome you're trying your hand at it, but even Buffett will tell you that K7000s can be simple to fix and then there are others that are next to impossible to figure out.
I need to re-read the whole thread to see what you've changed so far.
