Summary: We bought this TV November 2010 in a bundle which included a blueray player and 3D glasses. When the tv was less than 3 years old, we noticed a black line across the top 3rd of the screen. Apparently, according to other purchasers who complained on the internet, and even at the Samsung website, it is a line of dead pixels. I contacted Samsung customer services via live chat at their website.
Summary: This is a beautiful television. The actual set itself is thin, a really nice warm gray color, and has a super sharp looking metal base. Its picture is absolutely phenomenal. Everything I threw at it looked spectacular-games, movies, 3D, everything. It suffers from some slight IR of course, but nothing that was even remotely distressing, even after only breaking in for 90+ hours. All that said, it's on a truck on its way back to Amazon. Why? It BUZZES.
Summary: This is my first Plasma TV. I have 4 other LCD TVs. The reasons why I wanted to try out this Plasma TV was because of the price, high refresh rate, and 3D quality. The Plasma has any LED/LCD TV beat in all these catagories. And this TV is awesome...but get ready for a distinct buzzing noise that cannot be fixed. Your only option is to just turn the volume UP.
