I'd was experiencing occasional light pink banding, as well as some really annoying off colors on my PN58C8000 for a while. The middle of the field and the edges had a green tinge, and the spaces in between were pink. Noticeable (to me) on white or light blue screens, but not distracting enough for my wife or other folks to note it or complain. So I decided I'd live with it vs. going through the headache of a warranty complaint.
Fast forward six months, the pink banding had gotten a lot worse to where my wife was now commenting on it, and at this point I was 5 months out of warranty, so I figured I was screwed. I was actually shopping 2012 Pannys, etc. and cursing myself for not doing something about it sooner.
Long story short, I check up on this thread and called Samsung last Saturday morning and described the problem. They put me on hold for <5 minutes and came back saying I was approved for a one-time out of warranty repair. I get a call on Monday from the repair place saying they ordered the panel. The panel came in the next day, and they came out two days later to replace it. Brand new panel, zero cost to me.
A recall or something would be better, but still I think this was pretty decent of Samsung to handle it this way. So far the new panel looks awesome -- better than I remember the brand new one looking a year and a half ago when I bought the TV.
BTW, the "panel" is about 90% of the TV -- It seems like the only things I retained were the power supply, I/O board, and the bezel. I can't believe this is cheaper than just replacing the TV outright, but what do I know. Here's a pic of the replacement unit just as it came out of the box:
