Have you tried going to the service menu? Do this by holding "MENU" on the TV set while it is on, then pressing "Menu" on the remote. You may have to do this a couple times for the menu to appear.
There should be a option on the appearing screen for Convergence, which has more options the the standard menu. To work this under the "9" setting for convergence, each of the + on the screen is the corresponding button the the TV remote (3 if top right, 5 is center). Use your volume or arrow keys then to move the selected + in the desired direction.
