First try a static discharge this is done by disconnecting the battery then disconnect the power adapter with no power at all to the laptop. Then hold the power button down for 60 sec then put the battery back and plug it in and start it up. If this doesn't help try connecting to an external monitor .If this works then we know there's a problem with the screen . If this doesn't work we can now look at the motherboard or video card
