Any repair shop ought to be able to do this fix cheap (even an authorized 
dealer, though I'd avoid those if you have an option and the thing isn't 
under warrenty). It involves rotating the yoke (coil around the neck of 
the picture tube). It is definitely not just a matter of turning a screw 
on a circuit board, and involves being around high voltages, so I suggest 
leaving it to a pro unless you're familiar with working on TVs.

Seems odd the problem would occur with age, though. I'd expect it to be 
present from day one or happen when somebody installed memory or a disk 
drive or something and managed to knock the yoke out of alignment. In 
either case, I'd expect you could get it fixed free -- under warrenty or 
by the company who screwed it up.
