Why does my Casio LK-43 Electronic Keyboard have no sound when keys are pressed?

  There are several reasons why your Casio Electronic Keyboard might not be producing sound when you press the keys. It could be due to a power supply problem. Ensure the AC adapter is correctly attached, the batteries are properly installed (+/–) and not dead. Also, check the volume level by pressing the VOLUME button. If you have headphones plugged in, unplug them from the PHONES/OUTPUT jack. Make sure the POWER/MODE selector is set to NORMAL, not CASIO CHORD or FINGERED. If you've selected Tone '99 PERCUSSION', only the keys marked with percussion instrument illustrations will produce sound. Finally, ensure that LOCAL CONTROL is turned on.

To resume normal operation, simply press any button or keyboard key. This will return the keyboard to its initial power-on setting.

  If you're experiencing issues like a dim power indicator, the instrument not turning on, a flickering or dim display, low speaker/headphone volume, sound distortion, interrupted sound at high volume, sudden power failure, or continuous sound output after releasing a key while using battery power on your Casio Electronic Keyboard, it likely indicates low battery power. Replace the batteries with a new set, or use the AC adapter instead.

  If you cannot change the TRANSPOSE/TUNE/LOCAL CONTROL settings on your Casio Electronic Keyboard, it could be for one of two reasons: the keyboard is in Song Bank Mode, or demo tune play is in progress. To solve this, press the SONG BANK button to return to the normal mode, or stop the demo tune play.

  If a key light stays on, 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. Alternatively, press the START/STOP button to quit Step 1 or Step 2 play.
