My Samsung was fixed for "free." Call Samsung service 800 number. When asked why you are calling tell them it is about the white dots problem. The tech said he would help me solve the issue and provide me with repair order from a local Electronics dealer. I was given a work order number by the tech and did receive a call from the local repair organization. My DLP is over 36 months old so I asked if this was a "no charge" fix. He assured me that it is. Low and behold I am 100% satisfied with Samsung and the standing behind the product. The fix is a chip replacement that Samsung is well aware of.
