It seems to be a screen problem that needs to be fixed by an authorized lab.

This is what I found on another forum:

It sounds like your backlight is no longer working. Possible causes are ...

1) The fluorescent lamp (or lamps) for the backlight has failed or is cracked.

2) The high voltage DC-AC inverter circuit used to drive the fluorescent lamp(s) has failed.

3) The wiring feeding DC power to the inverter or between the inverter and the fluorescent lamp(s) has become disconnected.

FIxing any of these problems is not a do-it-yourself project unless you are very comfortable with taking apart the insides of your laptop and putting it back together correctly.
