What to do if my Korg Concert C-340 has no sound?

If your Korg Musical Instrument produces no sound, first ensure the volume isn't set to 0. Increase it to a suitable level. Also, check the PHONES connectors for any plugged-in jacks, as these disable the internal speakers. If a jack is present, unplug it. Finally, verify that the MIDI Local function is set to ON. If it's OFF, switch it to ON or try turning the instrument off and then on again.
