problem with LCD screen

    Have a LCD screen connected to a laptop but can barely see the image. Tried adjusting contrast etc to see if that was the issue but as I cannot see the image I'm not sure what I'm adjusting. But I don't think its as simple as that.

    The original power supply for the screen was lost so I'm using another supply unit. The rating on the screen is 12V DC 3A. While the output from the new supply is +12V 1.0A.

    I'm no use with electricity etc so could this be the problem i.e. the screen is not getting enough power or the correct power to work correctly ?

    Well theres your problem goof. Your screen is getting 1/3 of the power it needs to operate. You need to find a power supply that matches the one you had. Do not go over that - or you will fry the monitor. Come to think of it dont use the monitor the way you are now. could be just as damaging.

    Thanks - thats what I presumed !!

    No chance of damaging the screen cause I cannot see a thing - even squinting very hard!!!!

    Might put my decision to train as a "sparky" on hold !!!
