    I have 2012 MBP Retina with no backlight, and cant figure it out how to fix it.
    what it does is simply when I power it up backlight comes for a second and goes complete black, I mean no backlight whatsoever!
    there is no water damage or nothing as far as I know.(btw I know how to solder and change parts. I have rework station as well)
    my main guess is ,as of now , backlight fuse. however I don't know on these motherboards.
    Here is the short video of it

    Take it into apple?

    Given the design of the display panel, I don't think its really repairable and more likely it needs to be replaced.

    if you look at my post history i have posted a complete list of backlight fuse locations including pictures on all portable macs from 2008.

    you may find it there.

    you know how a fuse works right? measure continuity across the fuse, if the result is over a megohm then the fuse is blown.
