The invention discloses a microphone fault detection circuit. The microphone fault detection circuit comprises a controller and a vibration sensor, the controller is electrically connected with the vibration sensor; the vibration sensor is used for collecting a vibration intensity value of a microphone plate of the microphone; and the controller is used for generating and sending a detection instruction for detecting a microphone function corresponding to the microphone to the television mainboard when the vibration intensity value is greater than or equal to a preset vibration intensity value limit value, so as to determine whether the microphone board is damaged or not. The invention also discloses a microphone fault detection circuit detection method, equipment and a storage medium. Whether the state of the microphone board of the microphone is damaged or not is judged according to the detection instruction and the self-detection result, so that when the microphone function of the television cannot be used
