Does the laptop work with an external monitor? A trick I use is to turn it on with the monitor attached then close the screen soon as you turn it on, it should detect the external screen as the main display. You'll need a keyboard/mouse for this. If you get no display on an external monitor either, it's very likely the motherboard that is bad and not the screen.

1. Software - Try Fn + F5

2. Electrical - Remove battery, unplug power, hold power button for 60 seconds, turn on computer with power plug only, then shut down, add battery and restart
