If the buzzer is not functioning, first check if the buzzer has been muted or disabled, and verify the configuration operates the buzzer. Next, check and reconnect the buzzer lead if it is disconnected. If neither of these resolves the issue, the LCD/Keyboard may need to be replaced due to a hardware fault.
