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.

No it's not the connector, it's in good state like the other, i think it's a problem with the interface (i haven't VOUT on the U9410)
the VOUT is generate by U9410 not?
when i plug a thunderbolt gigabit, not detect on the system, the other port work well.

It can look good but in most non water damage cases it will be the issue. Too complex to mess with considering you have 1 working port. Again take my advice and don't mess with it.
