I hardly watch my Samsung HLS508SW picutre has an electronic wave or fuz around objects on the screen. Samsung replaced the DLP chip when it was under warranty. Slowly, the issue came back. Is there an known issue with the DLP chip? If I replace it, how do I know it won't happen again? How hard is it to replace a DLP chip?
Samsung claims they know nothing about issues with the chip, if there has been a recall or even if the chip has been redesigned. There is a recall on the TV, but they claim not for my issue. Even though the set was under warranty the first time it was reparied for the same issues (I neglected to mention that there are also black lines through the set like a grid) and they replaced it, they are saying that they aren't going to do anything because it is no longer under warranty. I can either pay close to the price of the set to have someone out to fix it or purchase a new TV.

First, check the optics in front of the light bulb for dirt. This will require disassembling the lens section. There is a youtube video that is most helpful. If after you go through the cleaning process and the dots are still there., the DLP chip needs to be replaced. You can get the parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy
You will need the DLP chip replaced to get rid of the white dots. You can call samsung at 1-800-samsung or you can buy the part from Suburban-electronics.com for $170.00. You really will need a technician to replace the part, very invoved proccess. Part # is 4719-001981.
The DLP chip is failing, causing white dots to be displayed. This is a common problem for Samsung DLP tv's. Depending on who repairs the unit, you can expect to pay around $300.00 just for the chip, plus 1-2 hours labor.
Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

The part # all depends on which version of the set that you have. Take a gander round the side of your side. Right side, if memory serves. You should see a sticker with 3 lines. One for model #, one for serial and one for version.
On the off chance you don't see one, check around the left side of the screen and take note of the lamp code. Your version will probably be a PB01 or PB02.
Depending on the version, the part # changes. Either way, you're looking at about $200.00 for a DLP chip. That's just the chip mind you, not the DMD PCB that drives it, or the rest of the light engine that helps process that information. I have had, during the course of my career, replaced a DLP chip to address white spots on the screen and found that insufficient voltage from the power supply cause the issue in the first place, or that the light engine itself was a contributing factor.
If you were to replace the light engine itself, you would replace all three components here and guarantee yourself a solid repair. You would hit the LE, the DLP and DMD all at once by doing a light engine. Granted, the cost is substantially more, but it might be easier in the long run to swallow $600.00 for a completed set than to swallow $200.00 for a DLP chip that didn't fix the issue and now can't be returned. Plus, a light engine will literally take you 30 minutes to put in and be done. Maybe even less.
PS - Don't touch the surface of that chip. And when you remove the DMD, pull out the old DLP chip and insert the new one....you're going to have to have help. Someone is going to need to watch the screen while you manipulate the DMD--set on and running--to align it back to the aperture. Have fun.
Part #s: Version PB01 :
4719-001968 Version PB02: 4719-001981
If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?
