I can't say I'm familiar with any model JVC, but I don't understand how
the vertical IC is likely shorted if the problem is the picture being
too tall? He didn't mention losing vertical. Wouldn't there be an
internal pot or an on screen adjustment through a service code to
mediate this? I understand components age and fail, but I thought that
some adjustments like this may be necessary after years of use. I trust
your repair skills, just the vertical stuff doesn't make sence to me.
