Sounds like you have lost the back lights, so you cannot see the video that's on the screen. To prove that there is video then simply turn off the lights in the room and shine a bright flashlight into the screen to see the picture is there. Chances are the power supply is bad, suggested retail from Samsung is $140.00 after the core is sent back ($50.00), but here is one for $46.00 and no core: http://www.shopjimmy.com/samsung-bn44-00201a-power-supply-unit.htm
Sometimes the power supply can be fixed with new capacitors. Remove the back and check for capacitors on the power supply that has the top puffed up slightly. If you find any, replace them. These parts (capacitors) are available at places like Radio Shack. you can either replace them yourself, or take the power supply board and the capacitors to a local TV shop and they will likely charge $20 to replace them for you. The power supply is the module that the AC cord plugs into, and the value of the capacitors is printed on the side. Normally the bad ones are rated at 16vdc and they could be 1000 to 2200 microfarads. These capacitors will look like a cylinder with a silver top. Google bad capacitors on LCD HDTV and you will see mass data
