[SOLVED]820-2879 No Green light, No power

[JohnB8812]

Board was originally slightly liquid damaged.
PPBUS: 12.58 volts
3V42: 3.42

SMC reset chip and entire top edge of board looked awful so replaced many burned components including U6990. Still get 3.42 volts on PP3V42 and 12.58 volts on PPBUS despite no green light. Rest of board looks clean SYS_ONEWIRE: 0 volts Adapter Sense with KNOWN GOOD DC in board is also 0 volts (?). What do I check for next?

Resistance to GND on 3V42? If below 18K then MCP is dead.

Ok will check tomorrow I kinda thought that the moment I opened it lol I hate 2010 13”s

Resistance to ground 4.6K so dead MCP the end. Thanks anyway Duke!
