Hello,
I got a brand new lenovo laptop and i just change the screen since it keep going black and white but still got problem with the new screen. It keep on going black after a few seconds and i've tried your suggestion to change the power plan but it still the same and i even set the brightness to the lowest but it still the same. It goes black but i can hear everything. Do you know what is wrong ? Or is it something wrong with the screen inverter ? Please help me..

Hey there bella,

The problem could be either with the intverter or the videochip and not with the screen itself. 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. 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 this gives an idea. Happy weekend!
