Interesting suggestion.  I did a little more searching and read that
sometimes flyback transformers can crack from overheating or aging.
If the internal high voltage is creating a corona/plasma since it is
exposed to air, does it mean that my transformer is still OK?  I am
guessing if there was internal shorting, that the part would already
have gone bad.  Does the corona dope need to seep into the transformer
to fill voids or do I just need to seal the cracked surface of the
transformer?

Thanks,
tt
