The back light inverter board may have gone out or it is not getting the 24vdc from the power supply module. Start checking for voltage feeding the inverter board.

with the TV off. press "Mute" "1" , "8" , "2" , "Power" on the remote (one at a time). But be careful when in there, you can change setting to keep your TV from ever working again.
