So I'll sort of revive this thread. I've been annoyed by the line bleeding as well. I have a Panasonic 65S64. The TV is very nice, but the line bleeding is incredibly annoying, and it occurs often. I can imagine how bad it is while watching a show like The Office where you have characters sitting in front of horizontal blinds a lot. During the twelfth episode of House of Cards that I watched last night I noticed it a lot more than I would have liked. It's enough to have me reconsidering my purchase, but if I go back to LCD I'll have a few other issues to contend with, the most annoying is light bleeding/flash lighting, but I expected it and it was only noticeable in low-light conditions. Plasma line bleeding is noticeable all the time, when the content on the screen causes it to occur. I don't recall seeing it on my older Panasonic plasmas, but they weren't above 50" but it was undoubtedly there. As far as I know there is nothing you can do about it. Reviews fail to mention it, I suppose because it is inherent in plasmas and they assume everyone knows about it.
