The updated schematic for the ILPI354 VA board is a critical service document for technicians dealing with "dead set" or "no backlight" issues in budget LG televisions. The "VA" designation typically refers to the panel type (Vertical Alignment), implying the circuit is tuned for the driving requirements of VA LCD panels. The updated version of this schematic addresses previous ambiguities regarding the LED driving circuit and introduces clarity on the protection modes that often confuse repair technicians.

Before you replace IC501 or IC502, verify every resistor connected to its feedback pin against the updated values. Chances are, a single changed resistor (like R518 or R507) is the only thing standing between a dead board and a perfect 390V PFC output.
