If you are facing an issue of Dark Screen there are basically two reasons for that, either it's the Inverter or the Back-light.Make sure you are looking for the right and as recommended Inverter is where you should look first.

Now,it's better to get an Idea with the picture than to just read in the manual and waste time in figuring out which is what.To get an Idea of how to dismantle the Laptop and look for and change the backlight is this link Backlight Replacement

Last but not the least...don't forget to check a lot of videos at youtube...see if you can find one of yours. You tube Videos
Good Luck.
