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.

MOSFET driver often paired with the LED backlight circuitry. Voltage Outputs: Typically provides a stable output to the main logic board and roughly 17.5V - 18V to the backlight driver stage. 2. Device Compatibility Ilpi-354 V.a Schematic

This usually indicates a backlight driver failure . Verify if you have ~17.5V at the input of the driver IC (pin 9) and check for a ~3V Enable (ENA) signal from the logic board. This chip controls the brightness (via PWM dimming)
