Need Jadis JP80MC help

Looking for Jadis JP80NC schematic diagrams or even for a picture of power supply view with bottom cover removed. Need clear pictures to see values and components. Was sold a totally unit with a totally burnt power supply components. Surprisingly, unit is working somehow. Seller refused to take it back and return my money, so now I'm stuck. Have fixed a lot of equipment, but here I do need some help.Thank you, Mark.
