One of your two PPLED lines is damaged. You replaced the diode but the problem could be with the filters (L2200/L2210), the diodes (D8228/D8258), the Coils (L8225/L8255) or the PMIC itself.

You need to probe the circuit to understand what seems to be failing. Check for continuity on the filters, shorts on the lines, measured voltages etc. Let us know what you find and we can give you more pointers.
