  1. hey I am working on a buddies laptop. He has this problem where the screen is very

    dim the image comes on but is very faint. He bought a new inverter which did not fix

    the problem so we tried to connect a new backlight to the inverter which also did not

    fix the problem also we got a new lcd cable which also did not fix the problem should

    we just get a new screen or is it a problem with the motherboard. Thanks

    I would say a loose connection or a bad LCD cable

    As I said above it actually fixes the screen

    when it has this problem i just connect it and out of nowhere the screen works perfect. I've tested all the hardware Ram, Hdd & Mobo all is working fine

    hey if anyone has the problem with the screen being scrambled it was due to the circuit board on the lcd screen
