    Asus ux31a2 no power

    I have the above m/b which I have only 19v and 5v rails only.
    I checked for short on pu8100 on 3v side and everything was ok
    I disolder pjp8102 and on PL8100 I have 3.3v but 5v was missing.
    I checked for short on both pins of the joint but there was no short.
    I solder joint pjp8102 I have 5v but not 3.3v.
    If I disolder pjp8102 pin1 has 19v pin1 0v


    Can someone help!
    Thanks
