Have you replace the lcd inverter? if it works on external monitor, given the screen is new, then it leaves the inverter. Usually in the case of dark screen, it should be the first thing to check/replace.

Usually you need to take of the panel above the keyboard, it often snaps off, though sometimes there are screws on the bottom of the computer and you have to take off the keyboard too. then you can unscrew the hinges. Depending on what you have to replace you might need to take off the faceplate for the screen by pulling off the little rubber things and unscrewing the screws hidden beneath. If you need any more help just post back.

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.
