Hello, I currently have a Alienware 17 and the display currently is not turning on, but all the keyboard lights are

I current am having trouble with my Alienware 17 laptop. I bought it last year and it was working just fine. All though, a few months ago when I went to turn the laptop on, the display wouldn't turn on while the keyboard lights still were on. I decided to leave it alone for a couple weeks and still the display isn't working. Any solutions?
