I have a similar problem where small white little dots appear on the left side of the screen. this is most noticed whenever there is a black background only. they appear if I am watching a DVD connected via component or my satellite via HD-MI. Any suggestions are greatly appreciated.
Thanks

Re: White Dots (Plazma)
The symptom sounds like a common problem we have found with the plasma panels called diffusion.
The cure in Samsung usually is a VSCAN alignment.
Since its an SPS-4243 the unit should be under warranty and is covered. Call 1-800-SAMSUNG and they will direct you to the nearest service center.

Your TV is DLP projection TV. DLP is Digital Light Processing. Digitally processed light coming out of DMD (Digital Micro mirror Device) is projected on the TV screen. This DMD is made of thousands of tiny mirrors & the size is about 0.7 inch. These mirrors are fixed with tiny hinges for its movement. They reflect light as per processed signal. DLP is invented by Texas Instruments. When there are dots on the screen, that means the tiny mirrors representing the dots are stuck in its position. If the dots are few & the viewing is bearable, just leave as it is. If the dots are more than bearable then you will have replace the DMD chip which is quite costly.
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..
this seems to be an issue either with your DMD board or with your Digital Video board...
turn on the tv and go to the menu if the white dots appear on the menu the issue is with your DMD board but if they don't show on the menu, the issue would most probbaly be with your Digital Video board
It is a timing problem with the cable, you will only get it on 1080p. Is your cable particularly long, or are you using an adaptor (2 x Cat5e network cables)? Try a different cable.
