I have a Mitsubishi WD-60C9. I bought it new and I have had it almost exactly 2 years. I changed the lamp for the first time last month. Now, I have noticed several white dots on my screen. I did a quick Google and I see that this has happened to a lot of people. There is even a Facebook page that is almost completely dedicated to the "white dot issue": http://www.facebook.com/#!/pages/I-have-a-defective-Mitsubishi-TV/129065190473390 It looks like Mitsubishi is sending a replacement DLP chip and "possibly" paying for half of the labor for a lot of posters. We'll see.... It seems like in almost half of posts I have seen, the problem started right after the lamp was changed. Why does changing the lamp cause this? Thanks in advance!!!
