I currently don’t have a good display to test with.
There was some liquid damage on the camera connector. After cleaning I verified that all pins are good (no shorts). Here's what I got so far:
• 5V power rail goes to the display assembly
• camera and ALS bus pins are at 1.8V
• ALS_INT_L is 1.25V
• FTCM_RESET_L never goes high when I try to use the camera

Resistors are good. I replaced UD120/40 and UP420. No change. The LPDP_FTCAM_DATA bus remains at 0V even during camera access.

Probably a bad display? it's just curious to see both camera and ALS both nonfunctional since they have separate data lines.
