Schematic for the Sony MBX-224 mainboard used in the M960 and M970 projects, marked as the H model at revision SA. The H and L variants are separate boards, with a sister L model on MBX-223, so confirm which one is fitted before using this 998 KB PDF. MBX is Sony's own mainboard numbering. Use the sheets to follow power sequencing, locate regulators and identify parts connected to a shorted or missing rail, and check that the revision on the PCB matches.
