C7428 power supply is designed with wide voltage, which can adapt to the grid voltage of 110v-245v, and it is like the Toshiba 2500XH. The shift circuit of the gridTo adapt to the grid voltage of 110v-245v, the circuit is designed to be able to shift double rectification/bridge rectification. When the voltage is lower than 145v, it shifts into double rectification; when the voltage is higher than 145v, it shifts into the bridge rectification. After the voltage, which is input by the grid, is low-pass filtered, it is firstly rectified by V801 and V802 and C808 gets a recognizing voltage, then the voltage is imposed on the 2-pin and 5-pin of STR81145.
