Screen turns on but stays completely black

i can see the screen being illuminated but i cant see anything, i hear windows starting up and everything... what could it be?

If it's a laptop then the LCD lamp could be working but there's something else wrong with the LCD.

Can you see the bios screens and info right before the Windows starts?
