Verify output voltages from the PSU harness (+15V, -15V, +5V, +48V). If any rail is missing or sagging heavily, the PSU regulation circuitry or an internal short-circuit on that specific rail is responsible.
A complete breakdown of official Yamaha part numbers for ordering replacement faders, potentiometers, jacks, and internal boards.

The user manual provided in the box covers basic operations: gain staging, aux send routing, FX selection, and USB recording. It explicitly warns users not to open the chassis. The service manual, conversely, is written for certified technicians with oscilloscopes, multimeters, and soldering stations.
