I've been trying to fix a casio wk1630 for a friend. I haven't been able to find any circuit diagram manuals or pin outs for voltage readings. The keyboard comes on but no sound. When you press keys the display shows the key that was pressed but no sound. Also when you turn on the drums to play there is no sound. I have inspected every inch of the circuit boards and wiring checking for broken traces or cold solder joints and found nothing. I have metered all the wiring and it is all good. I did find some evidence of something getting spilled on it so I'm assuming one of the IC chips is bad. Just need a repair manual for it.
