My Samsung HL-S5086W had an electroinic haze and then a black grid. The DLP chip and DMD board were replaced, the TV worked fine for a short amount of time and the haze came back followed by the lines. I don't want to replace the parts again if they tend to be defective...Can't seem to establish if there was an issue with the parts...

You are probably seeing what looks like Jail Bars (Vertical Lines evenly spaced) on the screen. If so,then the DMD chip on the DMD board is bad and needs to be replaced
The random whit dots you are seeing is more than not the DMD or million little mirrors board. The white spots represent some of the mirrors that are sticking in the on position. In that case they are always reflecting white light from the lamp. I don't concider the DMD board a do it yourself repair since on the older DLP set it requires mechanical alignment as well. The best thing to do is contact a techincian and see what they might charge to repair the TV for you. Please take a few moments 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...
It seems you might have an issue with the dmd board.
Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.
My Samsung LCD has white spots on the screen. The tiny spots seem to be increasing in numbers. I am outside my warranty. Is this going to cost a lot. It is a 43in screen.
