Discharge the main filter capacitor using a resistor, not a screwdriver.
The primary section handles high-voltage Alternating Current (AC) processing and converts it into filtered Direct Current (DC).
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.
To help you with the specific problem you are facing with your ILPI-354 V.A board, could you tell me: Ilpi-354 V.a Schematic
The board is a combined Power Supply Unit (PSU) and LED Driver. It typically features: Primary Section:

It converts AC mains voltage into the low-voltage
Because the ILPI-354 features a dense assembly of components, interpreting its functions without a visual guide is remarkably difficult. As noted by Technical Resource Archives
