You'll want to go into your setup menu, and go into where it shows Magic Focus, and convergence. You'll want to select manual. You should get a picture of a grid on your TV screen with horizontal and vertical lines. All of these lines should be white, but if you're having a color problem, you'll be able to see blue and red lines outside of the white ones. Using the remote's cursor you need to manually go box to box and push down and pull up these red and blue lines, almost as if you wanted to hide them behind the white ones. Once you just see a clear grid of white vertical and horizontal lines, you're picture will be perfect.
