    Hy guys!
    I`m working on a Sony Vaio and the image is very dim! I think it`s an invertor problem but when I`ve got to inverter I have 2 power output to the screen i think this is because the screen is haveing 2 backlights

    Any ideea where I can read more things about Screen Invertors?

    Do you thing I can connect a screen with one backlight?

    Thanks,
    Andrei

    If your machined is designed with two back lights and you only get one working then I would expect half of the screen to be very dark. Couldn't your problem also be the backlight? They're normally a cold cathode fluorescent lamps. Here's a reference on that: en.wikipedia.org/wiki/Backlight

    New inverter didn`t solve the problem;
    I`m looking now for a new screen;
    What is strange for me and I don`t understand is the fact when I`m trying to connect to the laptop to an external monitor I don`t get any signal! This make me to thing video unit is faulty .... but on the screen still have dim image!?
    What do you thing guys?

    Best regards,
    Andrei

    Have you tried adjusting the brightness and contrast?

    Connecting external moniors may need a function key pressed. Consult your laptop's documentation.

    I think most laptops would require a Fn key to be pushed! If you have a dim image, it would seem the graphic circuit is working and it is the lighting that is the problem (inverter, backlight, of contrast/brightness settings).
