I'm working on a Sony KV2080R 19" color, fairly old, but the question
sort of relates to all tv's.

It worked well except I heard a few cracks and saw a blue light coming
from the back of the tv. It was a spark about 1 1/2" long from the
flyback transformer to another part of that, shaped soemthing like a
BIC lighter with square corners. Is that the tripler?

that object could be a fusible resistor.
In any case, if you mean to keep that tv, don't mess about wasting your
time with this botch repair. Just buy a new transformer before you end
up damaging the nearby circuitry- ICs dont tend to like being zapped by
20,000 volts ;-). check the reference in the www.hrdiemen.es website.
