Concluding note Use the structured sections above to map the actual NM-C561 schematic for GS44B / GS54B hardware: identify nets, populate tables with the real net names and measured voltages from the board, then apply the troubleshooting and modification guidance. If you provide the actual schematic file or photos of the PCB with legible silkscreen, I can extract pin mappings, populate the test-point table, and deliver a board-specific handbook with measured nominal values and bespoke repair steps.
