Ilpi-354 V.a Schematic -

Once filtered, the AC or fluctuating DC input passes through a bridge rectifier network (often designated as BR1 on the schematic).

Supplies constant current to the LED backlight strip.

The Ilpi-354 V.a is an integrated power supply and LED driver board (often referred to as a PSU/Inverter combo). It converts AC mains voltage into the low-voltage DC required by the monitor's main logic board and the high-voltage DC needed for the LED backlighting. Ilpi-354 V.a Schematic

When working with the ILPI-354 V.A schematic board, always follow standard safe electronics workbench practices:
