Just wanted to make a quick update about my TV. I'm now on my second and a half set. As I mentioned earlier, the first set started to have multiple dead pixels. After dealing with Samsung tech support, they approved a panel change. After a two week wait, the tech came out and swapped the panels. The new one (which is why I say half) had, again, multiple dead pixels. Called Samsung immediately - even though the tech said not to - and had to jump through hoops for a replacement TV (literally weeks of calling them back and forth talking to "higher ups").
My latest unit has 1 dead pixel. I've decided to keep it - for now, I'm hoping it'll go away as it has lightened up some - since this has been a 2 month ordeal and 1 pixel wont kill me. What bugs me, though, is the picture quality is drastically different on this TV. While the CNET provided settings were great on my other unit, they seem dull on this one. I've literally spent over 3 hours trying to calibrate this one and I'm still not satisfied. It only has about 200 hours on it, so I'm still hoping for improved quality but my first one had excellent quality by this point.
I've noticed others also have problems with dead pixels. Admittedly, I'm very disappointed in Samsung right now.
