<span id="ctl00_ctl00_MainColumn_CenterColumn_ThreadSolutions1_Repeater1_ctl00_lblSolution">DLP/mirror chip is going bad. A common problem on Sammy TVs after 2-3 years. Chip is user replaceable (try samsungparts.com or ebay) for about $150-200. Sammy was (last year) repairing the DLP White Spot problem for free. You MUST talk to ECR (executive customer service) to even think about getting that consideration--forget the standard CS people. Don't know if they are still covering this out of warranty in 2010.</span>

call samsung. there are aware of this issue with several of their dlp sets. To avoid a class action lawsuit, they've extended the warranty of several models to cover the very issue. give samsung a call and see if you model is covered. i just got my 46" repaired at no cost and without a warranty.

The random whit dots you are seeing is more than not the DMD or million little mirrors board. The white spots represent some of the mirrors that are sticking in the on position. In that case they are always reflecting white light from the lamp. I don't concider the DMD board a do it yourself repair since on the older DLP set it requires mechanical alignment as well. The best thing to do is contact a techincian and see what they might charge to repair the TV for you. Please take a few moments to rate my answer...Thanks..

Hi,

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...

If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?

Make sure you have firmly seated the new Lamp. The next step is to go to the rear of the set and put your ear next to the Lamp Door while turning "ON" the tv with your tv remote.
You should hear a short buzzing sound. That is the Ballast "Exciter" firing up to light the Lamp. If you do not hear this buzzing then you probably have a bad Ballast. Ballast part# is BP47-00037A

Samsung DLP Projection Tv white dots may caused by DLP Chip. Change a new DMD Chip 19106143W. The post show you how to replace it step by step.
