Samsung DLP white spots

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!

    Thanks for the info. I will take a look at it. Yes, the spots are stationery. Being a girl and not up on the workings of these HDTVs...yes, I come from the day of the old picture tube! I'm not sure where to look where "venting" is. Thanks for your help; wish it were a simple fix.

    Have you read other blogs and comments on websites about this problem with Samsung? Nothing positive about them, let me tell you! There are a bunch of people out there with the very same issues, who have contacted Samsung and they've totally blown them off. Nearly everyone has only owned their TV for 2 - 2 1/2 years. I do think I will compose a letter to their corporate office, though...hey, what can it hurt. Thanks for trying to help....anymore ideas, I'm all eyes!

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.

    I would not hesitate to call Samsung, The Imaging device rarely fails and if it is the device they should work with you and honor it.

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

My 46" Samsung DLP Rear


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.

I also have the white spots problem with my Samsung 46" DLP. My set is 2 1/2 years old, and was fine until a couple weeks ago, when 1 then 2 white spots appeared. Presently there are 10 spots and rising....


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...

Had one last week and now there are 6. they are


Hi,

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...

Pleaserate this solution,

Noticed 2 white spots about a week ago.


It seems you have an issue with your DMD board, so pretty much you will need to replace it, those boards are running around 180 dlls, it's worth to try, but eventually you will need to give maintenance to the Tv

White spots


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.

Numerous white spots on Smasung DLP TV


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 !

Numerous white spots on Smasung DLP TV


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.

Worked a charm on my 50" Samsung DLP. Read thread carefully as there are 2 different version of the DMD chip you will need to replace. I ended up fixing mine for less than $165!
