It's sounds like the backlight inverter part on the power supply board is bad. There's a place called shopjimmy.com that has pretty good deals on parts. The board for your TV is around 25-40 I believe and is an easy diy fix.

Either you have a bad panel or the T-con board is not processing the video to the screen. This is the board between the main board and the screen. There is one on E-bay for just under $35.00. Hope this Helps.:)
