If your set has C218, a 10uF 25V bi-polar cap, try it even if it looks
ok. Also take a very close look at all the electrolytic caps in the
whole set. Last Mits. I worked on, I changed about 25 caps because they
were either defintely leaky or I saw a bit of a brown spot on the board
under one leg. I changed caps in the video section, deflection, SMPS,
CRT board, etc.
