Hello Baba,

When the screen goes black, can you hear the hard drive and the fan spinning? If you do, but you cannot seea thing on your display. 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.
In situations like this it's recommended connecting the laptop to an external monitor to see will there be any video signal going out from the laptop. If it does go out, then there's a need for LCD inverter replacement.

Hope this helps. Have a nice weekend.
