Failed CCFL lamp or failing inverter transformer. Ilpi-354 V.a Schematic

This chip controls the brightness (via PWM dimming) and monitors the current and voltage flowing to the lamps. Common ICs used in these designs include chips from brands like Beyond Innovation or GreenPower. Have you noticed any like bulging capacitors or burn marks

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. The Switch Mode Power Supply (SMPS) Section Common ICs used in these designs include chips

The output side of the inverter transformer produces extremely high AC voltages. Do not attempt to measure this voltage with a standard multimeter, as it can damage your meter or cause a severe shock.

The large filter capacitor on the primary side can hold a charge of over 300V DC long after the board is unplugged. Use a high-wattage resistor to safely discharge it before touching the board.

Do not just replace the fuse. Check the main switching transistor/MOSFET and the bridge rectifier diodes for shorts. If you replace the fuse without fixing the short, the new fuse will blow immediately.
