The memory buffer of the image processor overheats and the data in it gets corrupted.
Take your tv apart and clean it's interior very thoroughly, check the air vents for obstructions and the fans(if your tv has them). Finally after you reassemble it, make sure it's in a position that allows a good air flow for cooling.

GREY SPOTS ON BACK OF SCREEN NOTICEABLE WITH WHITE


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!

Very small black spots scattered over the screen


It sounds like you have some dead pixels. If those spots move then it may just be your graphics card. How long have you had the monitor? How long have these spots been there?

How do i fix or get rid of a green spot and a couple of purple spots on the tv screen?


Does your model end with a "5" as in PTnnLCX65? If so call the Panasonic call center to schedule service or find a servicer, they have a fix for colored spots on the 2005 MMDs ending with the number 5. The fix is being coverd under warranty.

Samsung DLP white spots


Are the spots fixed or do they move with the image? Verify that all venting is clean of dust. If the spots are fixed and upon close examination are a square shape, The device is overheating of failing. If the spots are moving with image it's a front end problem, and can be overheating as well.

Screen spot


Since you have a black spot,you need to look at the mirror or inside screen. If it were a certain color, like purple or yellow, for instance, I would suggest a lens or picture tube, but, since it is black in one spot, I would suspect debris in those areas.
