You need to set your convergence. Check your owner's manual on how to do it. I'm not sure the exact procedure on that model, but usually you can find it in the setup menu of the tv. What you're trying to do is line the red and the blue up perfectly with the green so that they all blend together to give you one picture.

More than likely you need to replace your IC's on your convergence board. Im not entirely sure on this model, but it's probably STK392-110. There are a lot of people that recommend that you replace them with STK392-150 to ensure a longer life.

If you are in the service mode, pressing the muting button saves the convergence values to memory.

Have you got the cable connected properly and attempted a consumer convergence in the menu? If you've attempted that and are still having the issue there may be other components on the Conv Module that have failed.
