I have a Magnavox Projection TV Model #55P828899. One day in the afternoon after turning it on, it started having a blue shadow around the graphics. I have adjusted the Convergence Blue, still have the shadow. I tried correcting the convergence Multipoint. Nothing adjusts. Is there anyway to put the TV back to factory defaults?

I tried following the directions in the user guide link listed below.
