Ilpi-354 V.a Schematic (2027)

The is a power supply board commonly used in Dell monitor models such as the SE2216H , SE2216HG , E2316H , and SE2218HV . While a full, high-resolution official schematic for this specific board version is rarely released by manufacturers, technicians often rely on component data and similar board layouts for repairs. Key Technical Details & Components

Primary side failure (fuse blown, dead MOSFET, or faulty PWM IC).

Open LED backlight strip or a tripped over-voltage/over-current protection in the LED driver zone.

If you are looking for a physical replacement, this board is widely available on secondary markets like eBay and AliExpress under part numbers such as or 491A011H1400H06 . Ilpi-354 V.a Schematic

Working with power supplies involves exposing live capacitors that can hold a lethal charge even after the monitor is unplugged. Always discharge the large filter capacitors before touching the board.

If you lack a dedicated hardware schematic document or specialized soldering equipment to safely debug high-voltage circuitry, swapping the entire power board is highly recommended. Complete replacement units are readily available on online marketplaces like AliExpress. To replace the board: Disconnect all external video and power cables.

Measure in diode-test mode. Forward bias should show roughly 0.15V to 0.4V for Schottky types. A reading of 0.00V indicates a dead short that forces the SMPS into hiccup-mode protection. The is a power supply board commonly used

The defining feature of the ILPI-354 V.A schematic is its current monitoring capability.

AC Input → EMI Filter → Bridge Rectifier → Bulk Cap → PWM IC + MOSFET → T1 Primary | T1 Secondary → Schottky Bridge → LC Filter → Voltage Divider → TL431 → Opto → Back to PWM | └─> Current Sense (R32) → IC1 (Current Limit)

This is the entry point for AC power. The schematic details components like the fuse, varistors (for surge protection), and the bridge rectifier that converts AC to a rough DC signal. Always discharge the large filter capacitors before touching
