Measure raw input voltage at the first MOSFET. Verify if the step-down IC creates the LDO outputs. VCORE VRM, APU Display Logic, LVDS/eDP Connector The schematic diagram for this board is a

If the board is receiving power but producing no sound, the schematic will help you locate the or Standby pins. Many implementations of the LM495 include a logic-controlled mute function. If the transistor driving this pin has failed (common in the MB-series boards), the amp will stay silent forever.

: Many technicians have reported boards that died after a screw or other metal object fell into the chassis and shorted something on the board. Check the board carefully for any physical damage, particularly near the screw mounts.
