Mine started with only one small white dot..... just a week ago, now I have a freakin constellation!!!! (at least 30) . I am gonna call samsung today to see if they will cover this even though it's out of warranty. I believe it to be the micro mirrors
The projection engine have problems,it the cause.Two years tv shouldn't have this problems already.Call talk to mitsubishi,might get some help the cost of the repair.
yes it will keep geting worse the dlp is is going bad the mirrors on it are getting stuck they may appear as black dots or white dots. the dlp ic needs to be replaced
The DMD chip is failing. The little mirrors on it are sticking in the on position therefore always reflecting the white light from the lamp. The part number you will need is 4719-001981 and is available from the Samsung parts website. I have included a link to directly purchase the part from them. Please take a moment to rate my answer. Thanks...
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.
same problem for me ... check out this thread on AVSforums about it.
I have the same exact tv as you and had the same problem. I took it to a repair shop who told me I needed a new DMD chip and that it would be 850 to fix. I used the information in thread above to get the part number and bought the chip on ebay for under 200. Here is a link to the listing CHIP
People have had good success. I will be replacing mine tomorrow.
Sounds like the screen burned out. Any water damage? Check the sticker on the phone (white box near battery) if not. Call your cellular provider and get the phone replaced.
