Hi
I have this board 820-3462 the thunderbolt port near the magsafe board don't work.
I check some voltage:
PP3V3_SW_TBTAPWR pin 18 U9410 = 0V
PP3V3_S4_TBTAPWRSW = 3,3V
I compare the U9410 and U9610 in diode mode all pin, that all the same.
i think it's the VOUT failed on the U9410 but some component behind, is it possible another component?
thanks for your help.
