It sounds like your color wheel. If you are handy at all you can change it pretty easily for the price of the part (probably around $90-$110) and a couple hours of your time. Here is a link to a video showing you the step by step process. http://www.youtube.com/watch?v=Cx4pbNjsxfU good luck..

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,color distortion or white dots on screens. 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!
