PDF schematic for the Sony MBX-187 mainboard, with IRX-5040 also named, likely a related model or part reference. Around 735 KB in size, it gives the circuit detail needed to trace supply rails, follow signals and identify components by designator during board-level repair. Use it to localise shorts, missing voltages or failed regulators. No revision is given in the name, so read the revision silkscreened on the PCB and compare it with the title block before relying on component values.
