Panasonic 27" Squashed Picture
 

Hey guys,
I have a 1992 Panasonic PC-29XF10A 27" TV.

Since about 2 days ago, a ~2" black bar appeared at the bottom of the
picture and the remaining picture on top of that is compressed
(squashed) vertically.

Does anybody have an idea of what components went? And how to figure
out which ones to replace?

Haven't repaired any TV's so I am a bit lost when looking inside of
one, so if anyone can help me in terms of physically locating the area
that went, that would be great. Or if anyone has a diagram or
component #'s for that specific model, that would be even better.

Thanks guys,
Jim

Look for capacitors in the vertical deflection area that have become
high in ESR. Or, replace all the caps in that section if you cannot
properly test them.

If you are starting to have bad caps in the vertical amp section, it is
possible that there are others in the rest of the set, that are starting
to also go bad.

Ive had tvs that did this, and it was either those capacitors, or the caps
and vertical drivers, I change all the caps in the section and the drivers.
