Yeah...
I grew up fixing television sets in the family
business... thankfully I
don't do that schtick anymore.
I had a tv repair business in 1974, and also worked on them at later points
in time. Not something I'd particularly care to go back to any time soon,
either. :-)
I'd agree, the shrinkage of horizontal deflection
does make it less
likely to be the transistor, but I've seen it before and therefore it
would be my first choice to check.
It would be unlikely to be the transistor if it was opening up, but if it was
shorting it may be loading down the supply to the extent that it would shrink
the horizontal some. Or the supply for the vertical may be flyback-derived,
which would mean that a short there (whether it's a transistor or a bad
electrolytic) would load down the flyback a bit more. But yeah, that's
where I'd start looking too.
