I have white dots on the screen of my hsl4266wx/xaa?

the DLP chip is defective and will need replacement. thats what causes the white dots

White dots that increase in number as time goes by indicates that the DLP chip needs to be replaced. Samsung use to cover this problem under their "white dot" warranty. You can call 1-800-samsung to see if they will repair it. If not, they can give you the closest service center. I would not attempt this repair unless you are a trained tech.

Buy a new DMD Chip and replace it yourself only cost you $159 which save at least $100 to ask a repairing center to do it for you. Check the video how to do this. Source: DMD Chip replacement tips And your DMD chip should looks like

Samsung just told me they wouldn't fix my tv because it was produced in Nov. of '06 and the only ones they would fix were made in August of '06 or earlier. I am way too angry right now to call the service tech number they so very nicely provided.

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..

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.
