Hello all.
I have finally found what I believe to be the problem with this macbook.
this is not my first post regarding this repair.
The macbook does not boot.
main power rails are present.
u3900 gets hot fast after it has mag plugged in. But no boot and no power.
has anyone got any recommendation as to what I can do about this.
The board originally had water damage around r1661 the test point for r1661, r1663, r1669 were completely corroded.
R1663, r1662, r1664 have been removed.
but I dont see how they could cause u3900 to heat up so much.
any suggestions or advice is appreciated
thanks
