Check the secondary windings of the inverter transformer using a multimeter set to the resistance (Ohms) scale. If the board has two transformers (or a dual-winding transformer), compare the resistance of the high-voltage windings. They should be within a few ohms of each other. If one measures open or significantly different, the transformer is defective. The is a power supply board schematic primarily
