Hello haryto,

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. 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.
What kind of "stuff" do you plan to change? Are you able to hear the fan or hard drive spinning at all? If your laptop is out of warranty, I suggest you to take out the drive and connect it to another PC through SATA-USB adaptor. If it gets recognized there, make a full backup of it.
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 that I helped.
