I have a samsung projection TV, Model# HL-P4663W. I recently Changed the color wheel in it and now the colors are reversed(skin is blue the sky is pink) Does anyone know how to correct This?

A model number would be nice because Samsung has basicaly two models to deal with, the one I suspect you have is the newer one and usaly the fix is easy, On the DMD board ( this will be the board mounted on the light engine ) there usaly is a small hole and what looks exactly like a jumper lead that they use for computer hard drives, if youres has the jumper installed remove it, this tell the DMD board what type of color wheel you now have. But do not remove the DMD board from the engine if you can not find this jumper because they are a pain to realighn
