Mitsubishi that the one,who u should contact.Talk to them make some kind of deal with them to help u to do a repairing or replace the tv Light Engine Projection Block.That the tv problems,this problems a design flaw on the tv Light Projection Egine Block the IC they put in that causes of this white spots are showing up will continue showing up more and more white dots.It will not stops.

I developed white spots on the screen of my Mitsubishi WD-57734 in increasing numbers over days and weeks. I called a repair service who quoted me $1500 to replace the light engine. He suggested I call Mitsubishi Customer relations at 800-332-2119 option 5 which i did. To make a long story short after several conversations with them they agreed to replace the part for free if I picked up the labor (Would have been less conversations if I had the original purchase receipt). Instead of $1500 I paid $250. The tv was only 3.5 years old. Perseverance paid off.

That is the first sign of the DLP chip failing ,the number of white dots will increase as time goes on.
The only solution is to have the DLP chip replaced, but it is an expensive part. You can call Samsung at 1-800-samsung to find the nearest service center.

I have the same problem. All of a sudden there are plenty white dots all around the screen. As if 1/3 of the pixels are burnt. It cannot be the lamp because it is still as bright as before. It must be the internal screen or whatever. The "Troubleshooting" section of the user manual does not mention such thing.

This unit uses a DLP (digital light processor) chip and if this starts to fail then you will get spots appearing on the screen. The DLP chip will need to be replaced.

Hi if your tv is a dlp it might be an issue with the DMD board 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!
