If you have a remote control for the tv go into the settings or menu input. Choose converge by pressing ok or set. A screen will come up with crosses on it. They are red, blue and green. Using the arrows on the remote, (up, down, right, and left), bring the arrows together. As the arrows move around the edge of the sreen hit ok or set up and work on them coming together. I just did this with my Panasonic rear projection tv. It works, but it takes a while to get the hang of it. Be patient, and when you watch tv you will see the difference.
I did not have a remote so I bought a universal remote controler for ten dollars and but my tv code in it. It worked fine.
Hope this helps
