Default Technics PCM Digital Ensemble PR305 Organ


I am trying to fix the above mentioned organ. This organ is obselette now and the authorised service centre is closed. This unit is totally dead, except for the front power indicator, the display, all the key illuminators are dead. I suspect it is a power supply problem. I just wonder if anyone has a schematic for this organ or similiar organ. I took voltage reading going into the microprocessor PCB and noticed the presence of +15 V DC and -15V DC but no 5V DC presence. I guess the processor needs a 5V DC to operate. Am I right, please advice.
