Akai MPC 2500 main CPU PCB assembly board alternative?

I bought an Akai MPC 2500 online from Guitar Center as a fixer upper. They originally thought that the LCD Screen was damaged but the repair guy in my hometown says it’s likely the Main CPU PCB assembly board. Unfortunately MPC Stuff only gets them when people give them parts. Does anyone know of alternative way to get this CPU PCB assembly board outside of getting it from MPC Stuff?

Think best bet is trying to find another broken unit of which the PCB board still functions, and then Frankenstein those units together into a working one. You might need some other parts in the near future too.
