i found how to get into service mode with the tv and have a list of what does what, but havent tried it yet. i dont want to fuck it up.

here is the issue

the screen makes a sad face. ie. the corners dip down a little. you can only see it when you are watching wide screen movies. i am just not sure with setting i need to fuck with, and how much i should adjust it.
the tv in question is a 32" sony XBR
