    Hi i got a laptop today and when i power it on, im greeted with a blank white screen, what ive tried so far is;

    Connecting to an external monitor which gives me an image and works fine.
    Tried the screen in a different laptop and its works fine.
    Tried a known working screen in the laptop which also showed up white.

    Anyone else ever comes across this or know anything about it.

    Any help greatly appreciated,

    thanks.

    Sounds like a motherboard problem, what kind of graphics card does it have?

    Yep, sounds like graphic card dead (mostly it happens with Nvidia chips)

    Pretty sure the graphics is Ati, ill have to check later, so is it normal for them to work on an external monitor even if the chip is dead+ Im also gona throw in a guess and say its not fixable.

    Hi Im pretty sure that if it work on ex monitor then its not the chip and its either the cable connecting the lcd to MB or its the screen itself but no the MB it is fixable but dont have an idea of cost

    its not the lcd anyway as it was tested in another laptop and it works just fine as for the cable to the MB I dnt have a spare one of them around to test but all the connections have been checked and it seems ok.

    the cable that conects lcd to mb is appox 20 1mm wires all it takes is for one of these to break inside its plastic coating and your lcd wont work try adjusting the cable with laptop turned on and see what happens or open and close lid slowly and watch the screen to see if the picture comes back, if it does cable is problem
