Before you order new convergence chips to try to fix the double vision or 3D look on your tv check the solder points for the chips. If you are able to smack the side of the tv or tap the heat sink for the chips and it corrects the problem than chances are the chips are fine butone or more of the solder points are bad. When I looked at the joints for the chips I noticed hairline cracks around the base of the joint. Re-soldering the joints for the convergence chips solved my problem.
