Thanks a lot, bro.
Keep up the good work like always.

This unit doesn't power on: simile dead. Will not accept charge or power up. These measure are taken right after connected to battery.
Does L10_AP come active when the power is put on ?

Bro you make another check but after you press power button without lcd and post result be careful to not short something.
Some coils output voltage after power button is pressed,Light coil and L9_AP charging coil output voltage after battery is connected.
Tell me readings after power button is pressed to see if voltage is supplied to CPU,RAM,Mass Memory,BB CPU,BB Flash etc.
In most cases if some voltage is missing or less replace that coil that is output of that missing voltage if not solve reball replace PMIC.
