    I just replaced my LCD. It was working fine, but now just stopped working. It's a mid-2009 A1286 15in Macbook Pro.

    The computer itself works fine and I tested it using an external monitor. I can FAINTLY make out the display on the screen, so I'm guessing it is a backlight issue? Don't mid-2009 don't have display inverters?

    I also tried resetting the pram and SMC.

    Check the backlight of the display, if you faintly see something then the panel seems fine.

    Since the new unibody don't have a inverter, does this mean its a logic board problem? The computer does work with an external monitor.
