Westinghouse TV no picture : Strip or fix?

[electroking]

Well, all the discrete components that are connected to V-6, in particular R-222
R-231, R-229, R-232, C232. The capacitor C-232 is only marked 400 V,
without capacitance, maybe you can locate it on the PCB and identify
it. You might bridge it temporarily with a similar one, without removing
the original. Be careful with those old PC boards, they were fragile even when
new!

Maybe you could try new tubes for V-5 and V-6, although the presence
of sound suggests that they are working.

I'm getting puzzled. Any other ideas, fellow AKers?
