SEGA Saturn Power Board Schematic

[black_kawa]

Hello guys, i have a Japanese Sega Saturn Model 2 here that the power board is releasing "the magic smoke". I want to repair it, but i want the schematics to help with the repair. I searched the net, but i couldnt find the schematic. There is any schematic on the power board for the japanese model 2? Or not?

Thanks in advance.
