Try using the function key for your display options
You should see a key related to your function key, generally a different color then the rest, labeled (F, Fun, FN, etc...) then look for a CRT/LCD, or LCD, or a symbol of a rounded square, or something resembling a monitor or screen.
Hold Fn and press that button, give it a few seconds. It should switch.
You can also hold a flash light up to the screen and see if there's any image, if this is the case then parts need to be replaced.
