Hello prabhat2k20
Have you tried to connect the laptop to an external monitor to see if there will be any video signal going out from the laptop? If you already haven't, please do so. If there's a signal going out and showing on the external monitor, then there's a need for LCD inverter replacement or the flex cable. 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 to think about during the weekend. Cheers.
