Just bought a new JVC 52" ILA. Great picture and all that -- but I had to exchange it because of a flaw on the screen. Up near the top left corner, there was what appeared to be a burn mark, or a stretch (like something had been pressed up against it), or just a blotchy discolouration. It was about 8-10" across, and had a streaky look like stretched cling wrap. This was only noticeable in a well lit room (during the day), and not noticeable at all when the TV was on. But I figured, for that much cash, better swap it. So I did -- and the new one has it too, though not nearly as pronounced. On this one it looks more like a faint light smear on the screen. Now I've never owned a rear projection TV before; my last one was a non-flatscreen non-projection CRT, so I'm accustomed to seeing a hard, flawless glass surface on my TV screen when it's not turned on. Am I just obsessing about this? Is it normal for these softer plastic screens to not be perfectly smooth and uniform looking, or can this sort of flaw be indicative of future problems?
