SOURCE: Hi, I have a projector Optoma EP7155 and it appear white and black spot like dead pixel, I would like to know where I can buy a DMD chip with the CCD and how much it will cost. Thank you

global projectors is one source. You need to find out from Optoma the chip you need or take apart the machine and look at it. From China they run about 200 bucks. I've only done Mitsubishi so far.

White dots on screen


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 screen. 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!

I have white dots on the screen of my hsl4266wx/xaa?


If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?
