Re: SAMSUNG LN46A550 P3FXZA - Weird Contrast & Discoloration issue

I had this exact model of TV: LN46A550P3FXZA with the exact same problem, weird colors on the screen: sometimes white where black should be and red spots pixels, pixelating, depending on the input used. It was the T-con board (not the motherboard despite the differences in the inputs). When I got a brand new T-con board (model #: V520H1-C06) from eBay for $32, and swapped out the old one, all my problems went away! I hope this helps someone else considering replacing their T-Con board!
