Yamaha CS5 repair

Synth Repair
1

I have a Yamaha CS5 which was left on when the wall power to it was turned off. When the wall power was switch back on the next day, it made a short sound and then stopped working.
Currently the power light on the synth comes on, but I get no sound.
Does anyone know what may have been damaged?

Check the two internal fuses on the power supply - if one has popped you may see just what you have. The power light is driven from the -15VDC rail, hence if +15VDC fuse has blown for some reason then you would experience what you see - power light but nothing else.
