Question about Samsung HLP4663W 46" Rear Projection HDTV
Pixelating dots all over the place on the screen sometimes comes on with all different colors. bad deal. any one have a clue.
Hi this is the DMD mirror (digital mirror display) that is missing the pixels on your picture. It is a difficult job if you have never changed one before. It is located in the DMD board that is attached to the light engine. You must take the DMD board off and then take it apart to get to the mirror. Take the mirror out of the bracket it is in and then replace it and put everything back together again correctly for it to work again. I would recommend a tech to do this.
