Try to connect your laptop to a screen via the VGA port and make this screen as secondary screen, and to see whether the secondary screen is still on when the screen of your laptop sucks. If the secondary screen is not on, there might be something wrong with you graphical card and you should replace the fan on the graphical card or CPU, because it is the heat that cause such problem; otherwise, I do not know.

Good luck, man.

如果外接显示器ok的话，就是你的屏幕日光灯管要换了。google一下，网上有教程，youtube上有step-by-step，教你如何更换背景灯管。
