1,white spots appeared on screen,means the DMD is broken,you need a new DMD.
2,the projector running off after only a few minutes,means the Inductor (Sensing element),near the Color Wheel. Use a cotton swab moistened with alcohol to wipe the Inductor.

White spots on TV Screen


<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>

I have white dots appearing on my samsung dlp.


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.
