"Stay Away from the PN50C450 and Samsung"2.0 starson by Dissapointed2Day
Pros: Great picture, 3 HDMI, multiple I/O
Cons: Heavy, glare issues, poor reliability, defective and irreversible firmware upgrades.
Summary: My TV developed a green vertical line. I upgraded the firmware to version 1008.2 as a potential fix. Now the vertical line is purple, there are menu items superimposed on light colored areas of the screen, and there is a grainy purple tint all over the screen. I found out from tech support that the firmware upgrade is not reversible. In other words, Samsung put out a defective software upgrade that really ruined my TV completely. I tried posting a review, with pictures, on Samsung's website.
