Rca 52 inch projection looks like 3-d movie

Question

I have a year and a half old rca 52 inch hi def ready projection tv. The convergence option is gone from the setup menu, and the picture looks like a 3-D movie. I am pretty sure it needs convergance chips. What else might it need? Where can I buy these parts, and how do I find out what kind of IC chips I need? The tv model is R52WM24YX61
