Hi friends, good afternoon...

I got a 16" MBP liquid damage and the mess was concentrated at the SSD region, front and back of the board... after some caps replacement, I'm having 5V at the ISL9240 but no PPBUS_G3H. When I plug the charger, it bounces from 5v 0.3amp and 5v 0Amp... Could it be a bad ISL9240?

Thanks in advance

Eduardo

PPBUS_G3H was shorted... I inserted 2.0V on the rail, found some components hot, replaced all and the last one that was keeping draining amperage was the R5620 (When I took it off, the power supply came to 0Amp. I'm trying to find this Resistor from a donator board... rough mission, until now.

Put back that resistor.
NEVER-EVER a resistor will cause a short to ground.
And NEVER again inject voltage into PPBUS_G3H in such manner.

You have short on PPBUS_G3H_SSD0_SNS, possibly U9580.
Your SSD is fried now more than sure.
