Question about Samsung HLR5067WX 50" Rear Projection HDTV
Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,picture will freeze,color distortion or white dots on screens.I couldn't find the Dmd by itself but found it with the complete light engine http://www.discount-merchant.com/SAMSUNG-BP41-00119E-p/1171034.htm?Click=48173 Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!
