Why is there no sound from my Casio LK-200S?

  Jeffrey FlynnAug 16, 2025
  There are several potential reasons for the lack of sound from your Casio Electronic Keyboard: * There may be a power supply issue. Ensure the AC adapter is correctly attached, the batteries are properly installed with the correct polarity (+/–), and that the batteries are not depleted. * The power might not be turned on. Check the POWER/MODE switch to ensure it is in the ON position. * The volume could be set too low. Adjust the MAIN VOLUME slider to increase the volume. * The POWER/MODE switch might be set to CASIO CHORD or FINGERED. Normal play is not possible in these modes; switch it to NORMAL. * LOCAL CONTROL may be turned off. Turn LOCAL CONTROL on.

  If the keys on your Casio Electronic Keyboard are lit but no sound is produced, it's likely a power-saving feature. The keyboard is reminding you that it was left on without any use. Press any button or keyboard key to restore power and sound to normal.

  If your Casio Electronic Keyboard song playback cuts out during SMF play, the data may be fragmented. You can try the following: * Save the data under a different name using the “save as” function without deleting the original data. Then, try using the newly saved data. * If the data was saved from another location, format the card (this will erase its contents) and save the data to the card again. Then, try using the newly saved data.

  If a key light stays on, on your Casio Electronic Keyboard, it means that the keyboard is waiting for you to play the correct note during Step 1 or Step 2 play. Press the lit key to continue, or press the PLAY/STOP button to quit Step 1 or Step 2 play.

  Mr. Thomas Weber DDSSep 12, 2025
  If playback stops part way through after transferring song data to your Casio Electronic Keyboard, digital noise from the USB cable or power cord likely interrupted data communication. Try these steps: * Stop playback, disconnect, and then reconnect the USB cable to the keyboard’s USB port, and try playing back the tune again. * If the problem persists, exit the MIDI software, disconnect and reconnect the USB cable, restart the MIDI software, and try playback again.
