Just as the others who posted here, my 2 1/2 year old 46" Samsung DLP started showing "white spots" about two weeks ago and now everytime I turn the TV on there are a couple more. What's up with Samsung? Before I bought this TV for $1500 I thoroughly researched HDTVs and Samsung rated the highest for quality AND service! Sounds like this isn't the case after all. I am so disappointed as I don't have $1000 to get the TV fixed or to even attempt to fix it myself. Is there any recourse we can take to "encourage" Samsung to stand by its products or is this just part for the course with electronics? This is the biggest TV purchase I've ever made and had hoped that the TV would last longer than 3 years! If anyone has any suggestions, please let me know..I really don't want to put this TV out on the curb!

Re: Samsung DLP white spots
Are the spots fixed or do they move with the image? Verify that all venting is clean of dust. If the spots are fixed and upon close examination are a square shape, The device is overheating of failing. If the spots are moving with image it's a front end problem, and can be overheating as well.
This are the dead pixels and will not go away. In fact number of "white" dead pixels will grow over the time. I am experiencing exactly same problem with my 2 1/2 yrs old 50" TV. No help from Samsung and I have no clue what to do. Any information will be helpful. Thanks

It's possible that the DLP chip is going bad. I'm not sure how much it would cost to repair it. If you have the part number you can search for it on ebay and probably find it cheap. I couldn't tell you how much it would cost to have someone repair it, or how to do it. I do know that diagnostics typically cost around 100.
There seems to be an issue with your DMD board, which is the on in charge of the pixelation. What you can do to confirm if it's indeed the DMD board, is the following:
GO to the menu on the TV and if the dots show in the menu, it's your DMD board, but if they don't the issue might be with one of your Video Boards.
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...
You get white spots inside the samsung DLP tv due to bad Digital Micromiror Device , or bad DMD board .
What is actually the problem is the DMV chip connected to this board . Inside this chip are 3 million tiny mirrors ,and when they physically get stuck , they either show black or white instead of a color
This is well know problem with SAMSUNG DLP...
The DMD chip is failing.If not under warranty expect to pay a few hundred to several hundred to get it fixed
The mirrors on the DLP chip are slowly sticking either fully open (white) or fully closed (black). The part that contains the DLP chip is the Light Engine. It is the most expensive part of the TV.Only the Samsung TVs has this issue.
Replacing the DLP chip and the micro mirror would solve this issue...
You seem to have an issue either with the video board or the dmd board, do the next thing, with the Tv on go to your service menu, is the white spots are still there, it's most probable that your dmd board is failing, if not, the issue is with your video board.
If your Mitsubishi TV has white spots in the picture , you can call Mitsubishi @ 1-800-332-2119 and request a free DLP Chip to fix the problem. They will send the New DLP Chip at no charge to a TV Tech in your area to install it for $200 flat rate. That is about a $250 savings if you had to pay for the chip . Call them with your TV's Model number and serial number and let them know when and where you bought the TV. It saved me some hard earned money and now my TV is like New !
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.
