I had the same problem with my SamsungDLP tv a couple of weeks ago. I had to clean the lenses, mirrors and the DMD sensor to fix it, you must remove the rear cover to do this. If the mirrors and lenses were cleaned but the spots were still there, the final thing to do is to clean the sensor chip on the DMD board. It is located under the heat sink behind the small fan in the lower center of the rear of the TV. The DMD board will have to be removed to get to the back of the sensor. All you have to do is blow some dry canned air across it to remove the dust, do not wipe it with anything. The repair is somewhat complicated and you will probably have to realign the picture by adjusting the position of the DMD board when finished.

Re: I have black spots on my samsung dlp tv
Yopu might an issue either with the DMD board or the Video board, turn pon the tv go the menu, if those black spots are still there, the issue is with the dmd board, but if they're not there the issue will be with your video board

It is the chip that controls the millions of mirrors inside the tv. If they are black, they are stuck closed. If they are white, they are stuck open. I JUST had the same the same thing happen with mine. I bought it 3yr and 2 months ago and I had an extended warranty on it for 3 years. Well, needless to say, it was out of warranty and I was pissed. The store I bought it from suggested I call Samsung. Which, I did. They asked for the model number and told me that my model (hlt5675sx) was one of the ones that is covered becasue they had a problem with the chip. Within 2 weeks, my tv was fixed by a repairman who came to my house. It works perfectly, now and it didn't cost me a penny. Good luck.
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.
This could be your video board going bad where your input cables are connected --OR-- the color wheel going bad. Hard to tell without a photo or reference though. Try swapping the cables first... and listen for any winding or whirring sounds.
This is a failure of the DMD board. The DMD board is the device that has the "million little mirrors" that compose each pixel of your display. The black specs are mirrors that are stuck in the off posistion therefore not reflecting any light at all. The white specs are the opposite reflecting light all of the time. This is a repair you should leave to a TV technician as once this board is repalced there is some electrical and mechanical alignment needed. Please take a moment to rate my answer. Thanks...
Hello: The problem is that a small mirror on the light tunnel has fell off causing a shadow in the picture,. In the past the only way to repair this problem was to replace the entire Optics Engine. But Samsung decided it was replacing entirely to many light engines so they decided to allow and train technicians on how to do it. It involves removing the color wheel and behind it is the light tunnel where light from the lamp shines on to a maybe 1 1/4 inch small block with three mirrors on all sides, your problem is that one of these mirrors has come loose from its side, causing a shadow with the pic still in the background. So if you call a technician to come, if he has'nt had the training from samsung on how to do the procedure then he will want to replace the entire optics engine which is the expensive way of doing it.
So when calling as if they know how to replace light tunnel. There are some adjustments that also needs to be done once it's replaced. To verify what i am saying go to this site to find out more. http://www.avsforum.com/avs-vb/showthread.php?t=758625

Actually I need you to do this... while the tv is on, go to the service menu, if the menu also has those twinkleish spots.. it's most probable to be your dmd board, if not, it's probable to be your digital video board
Are the spots fixed or do they move with the image? Verify that all venting is clean of dust. If the spots are fixed and upon close examination are a square shape, The device is overheating of failing. If the spots are moving with image it's a front end problem, and can be overheating as well.
