2013 Air board1.4ghz
Green Light/Switches to amber, no fan.
All rails present up to PP5V_S5 which measures at 1.72V
diode measurement at pp5v_s5 is 0.438
Checked around U7501 and it all "looks" fine. No obvious liquid damage to board.
PP5V_S4RS3 is next on the power rails, but doesn't that come from the I/O board? it is 0V (diode 0.421).
Known working I/O board, measures fine on another board.
Any help or ideas?
