820-02757: Not powering up on magsafe/usb-c except on battery

[repMacFixit]

Got this board, no sign of liquid damaged. The MagSafe light is off but once I plug in a usb-c it goes from 5v with some current draw to 20v but no current draw. This happens on both usb-c ports. The system ran while the battery still had charge. Suspecting the cd3217 chip for the MagSafe but wondering if there are anything else I can check. I’ve checked for shorts on all the components around the chip and all looks good. Also, like the A2442, does the chip have to be pulled from the same donor board and same position (I have a A2338 with the same usb-c chip or will a A2779 or A2780)?

Couple Measurements taken

PP3V3_UPC5_LDO: 3.4V
PP3V3_S2_LDO: 3.2V

CD3217 chips must come from same model donor board, maintaining the position also.

Compare diode mode readings around all them.
They switch to 20V if battery is disconnected?

The Magsafe light is controlled by charger, in base of the communication with the MacBook.
Do you get some voltages on the U5500 at least?
