Sorry partner, but you're wrong there. I own a Samsung LN-S4051, and it most certainly does have a backlight adjustment. It's called 'Energy Savings', and there are 4 settings, Off, Low, Medium, and High. High is the dimmest setting, and should be used for the deepest blacks.
Many people, include some reviewers, overlook this feature at first because of the strange name. But it does exist.
If you don't believe me, here's the link to the review of the 3251 in Home Theater magazine where the guy talks about it, and even gives the brightness measurements for the different settings:http://hometheatermag.com/lcds/906samsunglns3251d/
Please research your facts before you go spreading erroneous information. Thanks.
