Try an external monitor to see if it works. If it does, there is a problem with the display's backlight or inverter board.
If you were experiencing discoloration in the screen (pinkish lower light hues) before it flickered, that would indicate a CCFL backlight issue. If the screen suddenly flickered on you rather than a slow degradation the inverter would be indicated.
If the external monitor does NOT work, then you are experiencing a problem with your video card.
