    Firstly, confirm that all brightness levels (usually a keyboard function) are correct

    Next plug in an external monitor, to confirm all software settings are correct
    There may be a toggle function button, on your laptop to select external monitor
    Or just start the laptop with the external monitor plugged in

    If the external monitor works

    Then you have a hardware fault with your LCD screen on your laptop
    In most cases this is the Inverter board (electronic board in screen area)
    You would need to dismantle the screen to locate this part
    At which time, you could also check all internal connections

    Note: This type of computer servicing requires an experienced person, who will need to follow all power and anti-static recommendations
    You may also need to locate the dismantle guide for your laptop (if exists)
