The invention discloses a display screen blank screen processing method and system, electronic equipment and a storage medium, and the method comprises the steps: obtaining a vehicle ignition switch signal, and supplying power to a main control unit according to the vehicle ignition switch signal; when the main control unit detects that the whole vehicle is powered, vehicle power supply state information is obtained through detection of a vehicle application battery detection module; performing analysis according to the vehicle power supply state information and a preset working state condition to obtain power supply working state information, and determining power supply identification information of a system on chip according to the power supply working state information; when it is determined that the power supply identification information is a power-on state identification, the system on chip is powered on through a power management module so as to execute a display screen starting process. According to the embodiment of the invention, the blank screen problem of the display screen can be effectively relieved, and the reliability and stability of the vehicle-mounted terminal system are improved. The method can be widely applied to the technical field of vehicle machine fault processing.
