Hello,
I bought a roland VR 760 that the previous owner said stopped working. I suspected the power supply was the problem. I have bought and repaired many synths over the years. Unfortunately I can not find the service manual for this keyboard . I have check voltages, looked at the address and data line on the CPU and memories and found nothing strange. Nothing on the front panel works at all no LCD the button mostly dont light up etc. Im wondering if there is an internal reset I can do to see if it will come to life.
Any suggestions would be welcome
Thanks
