I too have a Sony 50" lcd projection set about a year old which also has, in my case, spots. For me this is not a huge problem as the spots, about three, are very faint and can be said to be without color as they are so faint. Since their appearance they have not worsened and with the exception of the lightest one in the lower right corner neither I nor any of my family can tell they are there except under very close sqrutiny. So, bummer. In the May issue of Sound & Vision the new sony Qualia 006 lcd projection is evaluated. In the article it clearly states that many manufacturers abandonned the earlier LCD projection technology since too many of the chips were flawed. I still think the picture is killer. The comment about the sony warranty line is right on in my experience. But if the spot is prominent I would be on their heels like.....well, you get the idea. Next for us is front projection, 1080p. Let me know how it turns out with Sony.
