I am seeing small white dots appear on the screen of my samsung DLP, it started with one last week and now there are 10. What would be the cause of that?

The DLP chip needs replacement that what causes the white dots eventually they will fill the entire screen assembly. You can get the replacement DLP chip with instructions from www.tvrepairworld.com

White dots are caused by the DLP chip failing.This part must be replaced to get rid of the white dots. Samsung is covering the cost to repair this problem on several models. Ypu can call 1-800-samsung to find if your unit is covered.

your dlp ic is going bad and needs nto be replaced. some of the mirrors are getting stuck they will appear as black dots or white dots. it usually starts as one or two and will continue to get worse over time.

This is a known issue with Samsung DLP sets. Here's a link to the solution:

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...

color wheel is failing and this repair cost thousand or more most of the time so i guess it would be better to dispose of or you may get lucky and find one on ebay but make sure you take care in installing

Bad Light Engine,Call UED for price of rebuilt one!
1-800-648-6657 TIP if you have never replaced color wheel,they 9/10 go bad also!

If the white spots are appearing in different spots or "Moving" it is the DMD board beginning to fail. Samsung DLPs seem to have a lot of DMD board failures. I would expect it to completely fail in the next couple months.

If there are only a couple small white spots that never go away it could be a mirror that is seized on the chip, but it's far more likely that the DMD board is going bad.

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?
