    Hi all

    Replaced my laptop screen when the colours all started going Negative. However, when i now turn on the notebook, the screen turns on but remains back.
    I've tried using the old screen but I get the same result. I imagine it may be the cable itself between the motherboard and the screen may be damaged, however what other solutions could I try?

    I've also noted that plugging in a Vga cable (with no laptop screen physically connected to the board) allows for an external monitor to be used. However if I try connecting the screen back up, the external monitor won't pick up a signal and turns itself off automatically.

    Probably the cable. Probably one or more leads got severed. Those wires in there are really small gauge and can get damaged pretty easily.

    A replacement is between £5-7 so I'm not hugely annoyed; are there any other potentials? Some magical button combo I need to try on boot?

    Hook to ext monitor and that will also tell you if the problem is cable or bad video chipset.
