well i would definitely check the lcd inverter, bring it to a shop if your not comfortable with taking it apart yourself. have them remove it and try using an external monitor. my screen just suddenly stopped working then you could make out the image then the laptop would shut off after a few seconds. if this sounds famliar then i would check on the part. you can find them on line fairly cheap. between 50 - 200 dollars us. i haven't replaced mine, money is tight and i have 2 other pc's to work on, so no rush to fix, but letme know if it works for you.
