820-00850 USB C port charge on one side only

[ajdoc]

Cant find any liquid damage.
One port charge only on one side, nothing on another side.

'Mac USBC & EDP meter" shows correct diode mode readings of JB500.
Replaced CD3510 just in cases and no progress.

Diode mode values RB630, QB630 are correct.

When plugged on the faulty side got 0V on FB200

Any idea?

Did you try with another USB-C connector?
Corroded terminals can't be detected checking on JB500.

Compare both QB630/40 readings with other channel.
