The 2 places I've sent such off to are ikenfixit.com and notefix.com

Since you don't see the display "light up" at all one common failure is the lcd invertor. The part is highly specific to the laptop. If the part is available you can find it with google. That's for you to find, not me.

Here's an example search.

If it's that, sometimes you can see something on the screen if you shine a bright light on it.

Best of luck,
