Hello again.
I have a 820-00239 that appears dead - no life, no fans.
No USB activity at all.
No signs of any liquid anywhere on either size of the board.
Tried with known good AC adaptor with just the bare board.
I don't seem to get 20v anywhere - the most I get is 5.7 volts.
I'm also fairly unfamiliar with and very confused by the whole USBC 4x ports setup.
With the charger connected to USB TA (JB500 outer USBC port)
PP20V_USBC_TB_VBUS = 5.7V (measured at FB200)
The other ones TA, XA, XB all read 0.0v.
UB400 appears to be getting hot, but nothing else is.
Any advice greatly appreciated.
