OK Thanks,

looks like the line stage. Did you remove the line transistor and
check b+? that should be one of the first tests when these problems
are suspected. From there check the vertical /frame IC - and before
changing it see if its feed resistor is open.

here's a few related stock faults as requested.
good luck.
