[SOLVED] 820-2936-A No green Light {corrosion under SMC}

[aurel476]

Another board with dark green light

PP3V42_G3H 3,47V
PPBUS_G3H 12,27V

U7000 :
SMC_BC_ACOK 0,6V
Pin 17/18 3,2 Ohms
Pin 27/28 20,4 Ohms

SMC_BC_ACOK line high

already replaced ISL

Bad SMC clearly ?

If SMC_RESET_L is high, bad SMC or corrosion under SMC.

If SMC_RESET_L is low, SMC is bad and pulling it down or U5010 is bad.
