Make sure that the energy-saving feature "Display Auto-Off" is not causing the black screen. Strike any key to bring the screen back to active mode.

Check that the display priority is set for the laptop screen and not an external monitor by pressing the "Fn" and "F5" keys simultaneously. If the screen is still dark, press the keys again to set the priority back to its original position.
Test the laptop screen by plugging in an external monitor to the laptop's VGA port. If the second monitor works, the problem may be with your Toshiba's backlight or inverter board.
