Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television
Had one last week and now there are 6. they are tiny white dots that are randomly placed. I have a samsung 46in. dlp hdtv. it's about 2 years old.
You get white spots inside the samsung DLP tv due to bad Digital Micromiror Device , or bad 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
This is well know problem with SAMSUNG DLP...
The DMD chip is failing.If not under warranty expect to pay a few hundred to several hundred to get it fixed
The mirrors on the DLP chip are slowly sticking either fully open (white) or fully closed (black). The part that contains the DLP chip is the Light Engine. It is the most expensive part of the TV.Only the Samsung TVs has this issue.
Replacing the DLP chip and the micro mirror would solve this issue...
Pleaserate this solution,

White dots on your RPTV television are the result of the DLP chip being
worn out. You can replace it very easily by buying a new DLP chip for
just under $190 and installing the new chip. There is a very good forum
over at fixyourDLP that offers tutorials for replacing the DLP.
or for Mitsubishi
