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.

Have a good day!

If the model above is correct you are describing a bad optical light engine, about the most expensive part inside that set.

On a WS-73735 the white spots usually mean a failing or damaged optical light engine.

It is a major part----Google the model number with "problems" or "light engine" etc.

<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>

BAD LIGHT ENGINE

It's a bad pixel spot. I have a TV that has a dark spot.
Nothing you can do about it.

Light Engine call Encompass Parts 1-800-638-3328 or try UED 1-800-648-6657 .you will begin to have more white spots appearing as time pasts .

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.
