Power sequence document for the Sony MBX-165 motherboard, ODM project MS90, in a compact 29.8 KB RAR. Rather than a full schematic, it describes the order in which rails and enable signals come up from standby to full power-on. Technicians use it to find where the startup chain stops on a dead board, checking each voltage and power-good signal in turn. Confirm the MBX-165 marking on the PCB, and pair this with the full schematic for component-level work.
