Ilpi-354 V.a Schematic [work] [EXCLUSIVE ⇒]

Users on Forum-Monitor.net.ru have documented pinouts for the LED backlight driver (DP860EGN) specifically for the ILPI-354 board found in Dell E2316H monitors.

Symptom 3: "Flash of Light" then Black Screen (Status LED stays Green)

A known issue where the monitor powers on but the backlight remains off or flashes briefly. Ilpi-354 V.a Schematic

If your monitor model matches one of the above, the fault likely lies with this power supply board.

Inside, the board is built around several key sections that work in harmony: Users on Forum-Monitor

Uses a precise TL431 shunt regulator paired with an optocoupler (e.g., PC817). The optocoupler translates voltage variations on the secondary side back to the primary PWM controller via infrared light, constantly adjusting the duty cycle to maintain stable output voltages.
