LED driving power supply control method, LED driving power supply and storage medium

The invention relates to an LED driving power supply control method, an LED driving power supply and a storage medium, and belongs to the technical field of power supplies, and the method comprises the steps: when an LED display screen is powered on through a preset LED driving power supply, judging whether there is a failed LED in the LED display screen based on a preset camera; if the fault LED exists, taking the fault LED as a fault LED, and positioning the fault LED to obtain a positioning coordinate value; judging whether the positioning coordinate value is within a preset edge coordinate range or not; if the positioning coordinate value is within a preset edge coordinate range, controlling all LEDs within the edge coordinate range where the fault LED is located to be turned off based on the LED driving power supply, and obtaining an initial display area of the LED display screen; obtaining a reduction ratio of the LED display screen based on the initial display area; and reducing the initial display are
