I've seen a few posts about smudges or clear stains on screens, especially Samsung DLP's .I have a samsung hlp5063,and am experiencing the same thing. The tech was here today fixing another problem, and I showed them to him. He says oh yeah, I've got 2 "screen kits on order right now for the same thing.....it's your screen seperating, and what you see is either moisture, or an air gap. He says if you press it with your knuckle, and it goes away foe a second, that will prove it. He was right, so any of you that wonder if this is o.k......it's not! My tv is going back anyway, but I thought I'd post this to help people that don't know.
