If the service menu is of no help, how does a technician fix geometry problems on a television?

Question

I have a crt hdtv with noticeable geometry distortions. I have tried everything in the service menu to fix them, but nothing has worked.

Assuming the problems are fixable and the service menu is of no help, what would a technician do to correct them? And is it practical to consider having this work done? Thanks.

The tv is a Samsung TX-p2675wh. The geomwtry problems are basically vertical lines are not straight from the bottom to the top of the screen. When they get to the top, they sort of bend off to the right. It's noticeable when a person is in front of a doorway, and the frame looks all crooked.

Answer 1

They can always replace the video board and see if that helps.

Answer 2

Whats the make and Model number of the unit? And a detailed description on what the picture looks like.
