I've been working on this board for some time now. It was slightly water damaged and had no green light and was missing some rails.
I changed the SMC and have green light and all my power rails. CPU gets warm. Fan spins for 8 seconds, off for 4 seconds, and on for 4 seconds, and will turn back on and stay on.
U7200 was hit the worst. Had to make jumpers and changed the chip. C6950 & C6951 hit with blown vias. U5810 pin 10 corroded and switched with one from 820-00165 board. U5660 pins 4 & 5 have a little corrosion but left alone; seems ok.
I have tried a couple SMCs and get the same results.
