    Hi Dave is the BIOS screen currently displaying as in picture in your post? Also if so is the video configured for dual monitors? If it connects Via HDMI then VGA possibly in BIOS is not selected properly..

    Reset your CMOS...

    Pull out your battery, power cable and any other screen plugged in, hold the power button down for 30 seconds, then plug your battery back in and power on, let me know how you get on :)

    On the other hand...

    It can't be an inverter or LCD issue as you can view the BIOS.

    Hi Dave, ive tried those tips, the laptop screen does have power to it as its a dim light black colour.
    Im wondering if i may have damaged the screen flexi cord taking it appart ?
    Ive looked at the cord itself and theres loads of tiny wires (impossible to detect a pulled or stretched one). :(

    on some LED models if you dont remove the main battery damage can occur to a diode.

    might need new LED LCD screen or cable.
    hope not mainboard.. it does NOT have inverter as its LED

    I agree with McG certainly checking continuity in cable would be where to start .. I hope it is a simple inexpensive fix Dave
