Mercedes-Benz display touchscreen failure is usually caused by damage to the touchscreen itself or a malfunction in the ADC chip that reads touch resistance values. Below is relevant information: Repair Method: For touchscreen failure, you can use a paperclip to press the RST hole (reset button) on the DVD to restore the device to its initial state. Function of the Central Control Screen: The car's central control is where you operate comfort and entertainment devices such as the air conditioning and audio system. The central control includes the central door lock system, allowing the driver to control the opening and closing of all doors and the window lift system. The central door lock system primarily has three functions: central control, speed control, and individual control. The driver can control all door locks, and when the vehicle reaches a certain speed, the doors automatically lock. Other doors have independent switches, allowing individual control of each door.
