You will actually get white and black dots , the black ones are tougher to see because of the color in the background , within 2 months youre picture will be fully covered with dots....I went through the Samsung website troubleshooting flow chart , and it led me to a bad Digital Micromiror Device , or DMD board . What is actually the problem is the DMV chip connected to this board . Inside this chip are 3 million tiny mirrors ,and when they physically get stuck , they either show black or white instead of a color . Samsung will not tell me the part number of the chip , they will only offer to send a service tech to my house .

If these spots are small, they are likely the visual effect of a failing DLP chip. When some of the tiny mirrored surfaces on the chip stop moving, this is the result. This is not something you can fix yourself. A Samsung authorized service center will charge $400-$500 to replace it for you.

See link below for "field of stars" fix:
Worked a charm on my 50" Samsung DLP. Read thread carefully as there are 2 different version of the DMD chip you will need to replace. I ended up fixing mine for less than $165!

Are they spots or dots? If they are spots then the optics are contaminates. If they are dots either white or black then you have a bad DMD chip. The cost of repair depends on who you hire to repair the set or if you do it yourself it depands who you purcahse the part from.
