This doesn’t look good Zach. The first thing you will need to do is check if 5V and 1V8 is getting to the connector, you will need the screen connected for this. Second you will need to diode the connector paying special attention to

·         90_MIPI_AP_TO_DISPLAY_DATA0_CONN_P

·         90_MIPI_AP_TO_DISPLAY_DATA0_CONN_N

·         90_MIPI_AP_TO_DISPLAY_DATA1_CONN_P

·         90_MIPI_AP_TO_DISPLAY_DATA1_CONN_N

You will need to compare these readings with a known good board. Without seeing how the phone is behaving it is difficult to diagnose over the internet. You could try clamping the CPU if you cannot find any irregularities with the connector circuits.
