You need the DMD chip replaced. Samsung is covering the cost of this repair so call 1-800-samsung and they will set you up for repair with the closest authorized service center.

SOURCE: White dots appearing on Samsung TV screen and multipling each day

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.

SOURCE: white dots on tv screen

The white dots that come and go could be what is called ignition noise. Caused by something in your residence or on the power line to your living area. You will have to do some tracking. Take a portable radio and tune it to the 550mhz, you will hear a crackle or buzz, tune to the loudest that the buzz/crackle can be heard. Walk around to see were the noise gets to be the loudest. If it gets weaker you are moving away from the source. The source could be a dimmer switch for lighting, or a loose connection on a receptcle, or in the panel box that supplies the residence. Worst case it could be entering from outside source. I have tracked ignition noise as far as two houses away that had a bad butter control on a refrigerator that was on the same power line that supplied the neighbor hood. There are so many things this day and age that could be causing your dots. Yours come and go, so you will have to track it when it is acually seen on your tv. Sounds like something on a timer like refrigerator, Furnace, etc.

SOURCE: Own a Samsung DLP TV 42 inch and white dots have

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..

I do I fix white dots on screen


Hi
Have you tuned the channel frequency tuner? Use the remote to bring up setup menu on TV, scan channel frequencies & save. If it's an old TV that can't pick up digital signals, then you need to get a digital set top box & tune to TV.

projection tvs can display white dots from the dust that is on the reflector mirror your lamp shines the picture on before it is reflected onto the front screen of your tv, one must be very careful when cleaning this, may be worth a service man doing it for you

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


If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?

Have little white dot's on screen will changing


Highly unlikely the bulb could be at fault; it sounds a lot like a defective DLP chip. If you are not aware of how this device functions, it is an array of physical mirrors which can fail individually and cause the effect you are having. The bulb failing would cause a loss of the entire screen, not just a few points.
