Hello David Danny,

In situations like this I usually recommend connecting the laptop to an external monitor in order to see will there be any video signal going out from the laptop. If it does, 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. Sometimes, after much of a use and less of a cooling the GPU which is responsible for video signal transmission gets unsoldered, the thermic paste goes away and it gets unsoldered, therefore the screen doesn't show anything. If you feel confident with the laptops' hardware you could 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.

Have a great weekend.
