[SOLVED]2012 A1286 820-3330 no green light, PPBUS_G3H AND PP3V42 Present ,liquid spilled
Hi,
having a 820-3330 board, got spilled on 1.back light circuit 2. a bit on u7000 and u8900 and a bit every where, but really nothing much screwed up.
cleaned off, soldered new back light connector(i know i should fix the power problem first, but that's quick so i replaced it anyway)
so long story short, U7000 replaced, 4 current sensing resistors connected to u7000 checked,all fine.
ppbus_g3h =12v, pp3v42 = 3.38v ,sys_onewire=3.3 , adapter_Sense=3.3
replaced u6900, r6990(was burnt),u6990. still same thing now, NO GREEN LIGHT.
on the other side of the board, looks totally clean, very sure only this side got spilled on, so can't imagine the SMC got anything under it.
any advice would be appreciated.
