I had the same problem with my Samsung TV.
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 .
