    Hi,

    A question.

    The upper part of the screen is very dark.

    Is this a bad inverter or a bad lcd screen?

    Thanks

    Depends, if it's led backlit you are most probably right, if it's the one which still has the ccfl light it could be the inverter or the ccfl lamp, but most of the time it's the inverter.

    none of the macbook non unibodys were led backlight. They were all CCFL.

    White Macbook Unibody and the aluminium unibody are LED backlight.

    So you more or less contradict yourself, it has a inverter and that means that it could be broken and not the display.

    Sorry, ill have to rephrase myself.

    "Happens with all macbook NON unibodies coming of age."

    Could only be an inverter or possibly another fault (damaged inverter cable or logic board) if the backlight fails to come on or backlight flickers NOT if you have partial backlight.

    In this instance the inverter is doing its job correctly but its the CCFL lamp at the top which is failing to power on thats causing the top areas to become dimmer.

    By all means justperry could be right but hey what do i know, im a newbie.

    Nothing to do with being a newby, you could well know more about things than me.

    But I have to disagree with the above, you say it's not the inverter and it's doing it's job, if there are two lamps(CCFL) there are two channels on the inverter so one could be gone while the other one still works.
    And I repeat, it might be the CCFL as well, it's hard to tell, but not the display as you earlier said.

    But this all doesn't really matters, the OP has a problem and he knows where to look.

    Cheers for now.
