    Test dusplay "backlight only" A1297 macbook pro 2010

    Hi

    I have image but no backlight. Fuse is blown. I think the display is faulty or cable lvds.. but not shorted last 3 pins in connector to GND
    .. Can I test the screen backlight only unplugged from motherboard with 32v at those pins? (Expecting to see a backlight only)?

    You won't see any operating screen voltages if the screen is disconnected. Check for shorts at the screen connector for backlight with the screen connected (no power obviously) and disconnected to make sure there is little or no difference. Replace the fuse once confirmed to check for proper voltages.
