My Toshiba Satellite L305 S5881 laptop screen won't come on, but occasionally will come on for no apparent reason, so I know it works. I've tried the shut off, pull battery, unplug and and hold the power button for 30 seconds thing and that didn't help. I've hooked a separate screen to it and it works. Please help

What will that look like? My husband took it all apart two nights ago, and could find nothing that looked out of the ordinary.
