HI.

I have an A1932 820-01521 with PP3V3_G3H and PP3V3_UPC_XA_LDO shorted.

I´ve replaced U3100 by an CD3215C00 (instead the original one CD3125C00Z).

However, the mac powers on once, and then PP3V3_G3H and PP3V3_UPC_XA_LDO gets shorted again.

I've already replaced 3 U3100, but with the same result (powers on once, and then stays at 5V).

On the last time, I saw a small sparkle on U3000 when disconecting the charger.

Can it be because the CD3215 difference?

Can you help?
