LCD Blank screen

I have a Dell Inspiring M4800. Recently when I try to turn it on, the screen flashes and then goes solid black. Pushing fn+f8 will turn it on until windows starts and then it turns off again. The function keys do not work anymore.

It works fine with the docking station or an external monitor. I can use the LCD panel in diagnostics mode, BIOS setup, and even windows safe mode, but when I try to boot normally I can't get pat the windows start screen wit out an exyernal monitor.

Any ides?
