plasma aspect ratio

Archived from groups: alt.tv.tech.hdtv (More info?)

?? Does it change aspect ratio during the same section of the DVD if the
audio is muted?? If so then it is probably an internal signal issue, if
not, maybe just a physical vibration affecting a poor solder connection
within the item or a possible cracks on one of the pcbs. ?? I Definitely do
not think it should be doing this on it's own accord. Having it checked by
an authorized servicer would be my first directive since it is "new" and
probably still under manufacturer's warranty.

The Panasonics have always been erratic in the auto mode. There is no fix
except to not use it. It seems to happen in certain brightness changes, but
we never could get enough info out of Panasonic to sort it out. They did
not seem very interested in addressing the issue. Just a lousy design in an
otherwise good product.

Probably not, may be best to actually start calling Panasonic Customer Line
and start getting them directly involved. Having a servicer that is familiar
with these sets and can actually get appropriate technical support from
Panasonic will also help. I agree with Leonard regarding the problems
Panasonic has when trying to assist their authorized service technicians.
Again, your first line at attempting to get this resolved probably will be
getting Panasonic directly involved, and a authorized servicer to have a
look at it.
