I think I've got a dust blob. It shows up as a blue circular smudge about the size of a small football on a black screen. As I can focus it down to a tennis ball size I guess it's dust, right ? Thing is after opening up and giving the panels some serious cleaning (especially the blue) it still hasn't gone ? If I can't remove it I guess I'm gonna have to send it back. On another note I noticed a small mark on my case. At first it looked like a scratch and it sits inbetween the buttons and the warning sticker on top. After looking at a few other AE500's I notice that they had this as well. It seems like the mould these cases were made in are probably leaving this mark. Any others have this on there case ?
