During the working process of the LED display screen, various faults, such as receiving and sending problems of a receiving and sending card, or faults of the LED display screen, are occasionally encountered, and the fault cause is difficult to judge under the condition that no picture is displayed so as to be convenient to remove. As a driving part of the LED display screen, the LED display screen control card is generally composed of a transmitting card, a receiving card, and a DVI display card. The existing LED displays are generally configured with a self-checking circuit, but most of LED displays do not provide an external display indicator or a control button of the self-checking circuit for reasons of use scenes, cost, display appearance requirement, etc., the self-checking mode can only be entered through configuration options of the display, and the configuration options of the displays of various manufacturers and models are different in operation, button modes are different, detection modes are different, when the control card of the LED display fails, the configuration options of the display cannot be entered, and part of LED displays even do not enter the configuration options or control methods of the self-checking mode.

Therefore, in commercialized and industrialized application scenes, if the LED display screen needs to self-check the state of the display screen, or check the connection state of the sending card and the receiving card, the shell of the display screen is generally detached, and after the condition of an internal circuit (such as observing the condition of a fault lamp) is checked, the self-checking operation is triggered manually, so that the maintenance, the disassembly and the installation processes are complex, and time and labor are wasted.
