Schematic — Ilpi-354 V.a

Arc over in the high-voltage section or dry solder joints.

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. Ilpi-354 V.a Schematic

The ILPI-354 V.A is essentially two circuits combined on a single physical printed circuit board (PCB). This integration saves space and reduces manufacturing costs but requires careful troubleshooting to determine which side of the circuit is failing. 1.
