    820-00239-A 20v on PPDCIN_G3h_CHGR, 0.77v on PPBUS_G3H

    Sorry, I meant to write 0.41 and not 4.1. ? It measures 0.41

    820-00239-A 20v on PPDCIN_G3h_CHGR, 0.77v on PPBUS_G3H

    yes, I measured diode mode. PPBUS_G3H to ground is 4.1V and diode mode between F7000 pads is 0V.

    0V at F7000 Edit: or do you mean PPBUS_G3H to ground? That is 4.1V

    820-00239-A 20v on PPDCIN_G3h_CHGR, 0.77v on PPBUS_G3H

    Hi, I am working on an 820-00239-A. Charger was stuck at 5V, after replacing UB400 I'm getting 20V 0,0A on other 3 ports, the port UB400 is responsible for is still stuck at 5V. PPBUS_G3H is 0.77v. PP3V3_G3H is 3.4v. Can UB400 be responsible for PPBUS_G3H not being created properly?
