Why does my Optimus Electronic Keyboard have no sound?
- BBarbara HernandezJul 29, 2025
If your Optimus Electronic Keyboard has no sound, even when pressing keys, there are several possible reasons: * The keyboard may have turned off automatically. Turn the power back on. * The volume might be too low. Increase the volume. * Headphones could be connected. Disconnect them. * There may be a power supply issue. Ensure the batteries are correctly inserted, matching the polarity (+/–). * The batteries may be drained. Replace them with fresh ones. * The AC adapter might not be properly connected. Ensure it is connected correctly. * If the MODE is set to FINGERED, you might be pressing too few accompaniment keys. Set the MODE to NORMAL or CONCERT CHORD, or press 3 or 4 keys to form a chord while MODE is set to FINGERED.
