Hi, White dots are due to bad DMD chip and qualified tv tech can replace required DMD chip in this tv to fix the picture issue. Please contact nearest Samsung service center or local tv repair shop for repair estimate. Thanks.
your dlp ic is going bad and needs nto be replaced. some of the mirrors are getting stuck they will appear as black dots or white dots. it usually starts as one or two and will continue to get worse over time.
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.
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
