Question about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television
You will actually get white and black dots , the black ones are tougher to see because of the color in the background , within 2 months youre picture will be fully covered with dots....I went through the Samsung website troubleshooting flow chart , and it led me to a bad Digital Micromiror Device , or 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 . Samsung will not tell me the part number of the chip , they will only offer to send a service tech to my house .

I have the same problem with my 2 1/2 year old 46 inch Samsung DLP. I have gone as far as to contact a friend of mine at Texas Instruments to ask if she has seen the problem. She told me exactly the same thing as cdietze6458. 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. Mine is 905 dollars. One thing I find very interesting is that if you search on this issue on the web you find mostly Samsung TVs with this issue. The other interesting thing is that the part number I need is backordered for 4 weeks. Also, they are giving a core discount/rebate if you return your old part. Are we feeling guilty Samsung?

See thread here for "field of stars" fix:
Worked a charm on my 50" Samsung DLP. Read thread carefully as there are 2 different version of the chip you need. I ended up fixing mine for less than $165!

All these posts were really helpful. I have the same problem, "white dots". I called Samsung - 1-800-726-7864. On a Sunday the answered! Got right in to a rep who was so helpful. She did ask for the model and serial number. Now, here is the big catch...if you have model HL-S5086W, they will fix this for free. However model HL-S5088W is not a free fix.
I had the 86 model, fortunately, They don\'t tell you which one is free fix until AFTER you tell them what you have! So they said a local TV repair will contact me in 2 working days to setup an appointment and replace the part. This is all free, no warranty, my TV is at least 4-years old, they didn\'t ask how long I had it or anything.
I was ready to pay for repair, or replacement when I stumbled onto this site. What a great solution to what I thought was going to be an expensive problem. Good luck i you have the same - good job Samsung.

Little white dots on DLP tv HLT5076sx/xaa that is only about 2 1/2 years old. Started with just 3, now up to 11 since 2 nights ago. Took meyestro's advice and called Samsung at 1-800-726-7864. They said that my TV was one of the one's affected by this problem, so they would give me a one-time courtesy repair, but if it happens that the chip is NOT the problem, then I will be responsible for the costs. Someone will call me back within 24 to 48 hours regarding the service repair.

Hi - My white spots magically disappeared when I called the satellite tv company - they moved the dish and the spots disappeared.... Dont know if this is your problem, but thats what fixed mine.

I have the same problem with my HL72A650C1FXZA. White dots all over my screen. I was told that it is not covered in warrant and I need to have a repair person come fix it. This is very upsetting. She is telling me that my model is not cover in the ones that get fixed for free because it is due to natural wear and tear. When I asked to speak to a supervisor she said there is not one but she can take down my name and number and have them call me back. We I asked why there is no supervisor there is said there was but they are on the phone with other people. I told her I would hold and then she hung up on me. Very very frustrating since I waited on hold almost 30 min to talk to someone now to be hung up on.

I am in the same boat with white dots on my HL67A750 TV. You can get a service manual here http://www.tradebit.com/filedetail.php/133052760-samsung-hl61a750a1f-hl67a750a1f-dlp-tv-service-manual
You can buy the chip at Amazon here. http://www.amazon.com/Samsung-Mitsubishi-Toshiba-4719-001997-Chip/dp/B007JY58FM/ref=sr_1_fkmr0_1?s=electronics&ie=UTF8&qid=1363053477&sr=1-1-fkmr0&keywords=Dmd+chip+for+hl67a750. For $159.
I only have 4 dots now, but if it gets worse i will get the manual and the chip as I described above. Best of luck.
Here is an instruction video from ShopJimmy. It may save the price of the Service Manual. They sell the DLP Chip on Amazon that I mentioned in my previous post.

I called Samsung but was told my TV wasn't one of the covered models so I will have to pay for it. I think that is bogus because the problem is systemic with all of the DLPs. Local repair shop said at $350 parts and labor. I went to the ShopJimmy.com website and watched the repair video. The part there is $84 and it looks fairly easy so I'm gonna try it myself.

Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
Here's a link to this great service
