    Macbook Pro Retina A1398 late 2013 (820-3662-A)

    Hi everyone,

    I have the following problem, see photo how i test the motherboard.
    Adapter start with green light and goes to orange and the fans are running directly and goes to high speed.
    I have measure a lot of points but , i don't know where the problem is. No chime and no display. Backlight is well on the screen .
    I think it is an heating problem but which components and where to look?
    I bought this macbook pro and it was with a cracked screen. I replaced the lcd but no screen only backlight.

    Can somebody help me or give some hints to look further
