Hey there dexter187,

Is the lappy just shutting down its screen or shuts down completely? Are the fan and the HDD continuig their work? If you can hear them, my advice is to connect the laptop to an external monitor to see will there be any video signal going out from the laptop. You can do that by using an HDMI or VGA cable /adaptor/ depending on the video output of the screen. If there's a signal going out, then you have to replace LCD inverter.
If there's nothing showing either on external monitor nor display, but the fans are still working, the problem that you have may be due to the failure of the video chip. Sometimes, after much of a use and less cooling the graphics processor which is responsible for video signal transmission get unsolders, the thermic paste goes away and it gets unsoldered, therefore the screen doesn't show anything. If you possess knowledge of notebooks' hardware you can change the paste yourself by opening the laptop and check if the chipset that is next to the processor has got unsoldered or you can bring your laptop to a technician to get it soldered again.

Hope I gave you some ideas. Cheers.
