It does not look like you are the only one experiencing some issues with the TV. Check out this thread from May:
If you'd like to spend a LITTLE bit more, you can always upgrade to an LED; for instance, the UN40C5000, another 1080p widescreen, could work. (http://www.sears.com/shc/s/p_10153_12605_05771120000P).
You can check out its product info on the Samsung page - http://bit.ly/dA93Kx
