It tests ok at 4816nF with 1.4ohms ESR. I need to work out a way of getting everything
connected together outside the case so I can do measurements. I?m hoping it?s something
fairly easy to spot as high voltage even at low current is daunting.

None of the pots on the video board deal with
contrast so I?ve got it out on the bench to remove and test the capacitors. What else can
I look at at the same time? Someone else has already mentioned the transistors Q101, Q102
and Q103 (on the yoke board).
Have you tried replacing C101? What happens if you temporarily remove
TR101?
