Question about Toshiba 52HM95 52" HDTV Projection Television
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,vertical lines,color distortion or white dots on screens. Here's a video for a samsung (It's the same technology as your Toshiba) that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q IO didn't find the DMD chip by itself but with complete light engine here http://www.discount-merchant.com/TOSHIBA-050915660-p/1172913.htm Have a blessed one!
