What to do if my Korg C-520 does not produce sound?

If your Korg Musical Instrument isn't producing sound, try these steps: First, ensure the AC adapter is properly connected to both the piano and the outlet. Next, check that the volume isn't set to 0; increase it to a suitable level. Also, verify that nothing is plugged into the PHONES connectors, as this will disable the internal speakers—if something is plugged in, unplug it. Finally, confirm that the MIDI Local function is set to ON (or turn the instrument off and then on again).
