I would like to know if anyone has experienced this on their DLP set. I've had the Samsung for a little over a year now. The other day I turn off my cable box and get the standard black image. A little to the right of center, theres a lighter spot where it's not as black as the rest of the screen. The closest thing I can compare to this thing is like a dust blob on a projector. I'm sure this isn't a dust blob for 2 reasons. It has a very distinct shape (like a half circle connected to a square) and when I turned the TV off and on immediately I saw something. What looks like a full circle starts to open, but doesn't seem like it closes, like it gets stuck half way, and that's where I get this half circle of light. Any help is appreciated guys, it's only a year old =/

Here's what it looks like:
