I have a Sony KV27EXR90 with a slight problem. A portion of the top

bottom of the picture is a little streched & distorted looking. The
middle
(aprox
2/3) of the screen looks fine. I have no schematic. Is this a common
problem? A
nybody have a suggestion where to look for for trouble?
This doesn't appear to be "hourglass alignment" - though I have no

Noisy looking horizontal lines appear at top & bottom of pic screen.
Image is bloated and noisy looking in these sectors.
Thanks for any replies.
