I just took delivery of my Panasonic PT50-LC13 and noticed there are two very noticable black dots on the screen. One dot actually looks slightly bigger than the other. On closer inspection, the bigger dot almost looks like a piece of dust, as it doesn't seems to take up a slight bit more space than one pixel. They're most noticable on white backgrounds, but even on the blue background that's shown when it's tuned to a station with no reception, you can still see the two black dots from 8' away once you know where it is. At the store, I had inspected another Panasonic LC13, and I had noticed there were certain pixels that had a permanent green color. But those were very faint, and cannot be seen by me from more than a few inches out. So I had just assumed that dead pixels would be faint like those, which don't bother me at all. So now my question is, are these black dots also dead pixels? I'm currently planning on exchanging the set, but I'm wondering if I should be able to expect a set with a perfectly clean picture from 8' out? Or are things like this just a part of owning an LCD RPTV?
