As shown in the table, Main_Pi and Spare_5V_2 is not giving an output voltage (we are expecting it to be ~5V).
Ryan said that there’s no firmware reason for both Main_Pi and Spare_5V_2 to both be zero and he suggested to take a look at the I/O expander connected to both Main_Pi and Spare_5V_2. More specifically, the following pins:
Pin | Reading (volts) |

14: MAIN_PI_DRVR_DISP_DSEL | |
15: DRIVER_DISPLAY_EN | |

18: 5V_SPARE_2_EN |
EDIT THIS:
i found out that led14 turns on when i pushed down on pin2 of U13 (fixed this by soldering)
i find out that led17 turns on by probing pin 4 of R89 (most likely soldering issue)
i find out that led22 turns on by probing pin 4 of R115 (most likely soldering issue)
(IGNORE FOR NOW):
