If you have have 40 vertical lines 16 pixels wide: DDP1011 or BCA, DMD panel interference: Replace the DMD board.

Mine is having the same problem. It started around Memorial Day and is only getting worse. One white dot is now a dozen. I called Samsung several times and was given the brush off. They clearly know this is a problem and are failing to respond to the problem in hopes that people will deal with it on their own. It does not matter if your warranty is expired. This is a latent product defect. They are still liable and obligated to fix the problem. I have filed a complaint with the better business bureau. If the company does not respond, I'm taking this to small claims court to get reimbursed for any cost to fix my tv.

Random dots or pixels failing on a DLP TV will be a bad DMD chip. This is a technician replace item only. The chip runs around 160 dollars list price. The part number will depend on which version the set uses and will be determined by the technician.

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..
