Re: Samsung DLP HL-S4266W White dot problem
Its the DLP IC chip itself that is bad. The DMD board is where the chip resides but if you order a board, it will come without the chip. Its not cheap and the replacement is tricky because the DMD board must be removed and then an alignment of picture centering will be necessary.

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..
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.
If the white spots are appearing in different spots or "Moving" it is the DMD board beginning to fail. Samsung DLPs seem to have a lot of DMD board failures. I would expect it to completely fail in the next couple months.
If there are only a couple small white spots that never go away it could be a mirror that is seized on the chip, but it's far more likely that the DMD board is going bad.
This could actually be an issue with either your DMD board or your Video board. With the TV on, select your menu, if the white dots are still there, the issue will be with the DMD board, but if they don't appear on the menu, the issue would be with the Video board.
Are they spots or dots? If they are spots then the optics are contaminates. If they are dots either white or black then you have a bad DMD chip. The cost of repair depends on who you hire to repair the set or if you do it yourself it depands who you purcahse the part from.
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
