Black Screen on L455D

 I could use some help on this.. The power lights comes on and  I have no screen.. just black. I have taken the battery out and disconnected the ac power cord and re-hooked them individualy . I can hear the machine run (fan) but have no screen. Am I missing a " turn your screen on button" somewhere? I have done the Fn F5 buttons and still nothing. Any help is much appreciated.
