Ilpi354 Va Schematic Upd May 2026

ILPI-354 V.A is a power supply and LED driver board primarily used in Dell monitors , such as the Dell SE2216H

Action:

Replace ILPI354 VA. Before powering up, check MOSFET gate for shorts and replace D3 (VCC clamping diode, 18V zener). ilpi354 va schematic upd

: If the monitor has a picture (visible with a flashlight) but no backlight, focus on the LED driver and its associated resistors on the 9th pin. Replacement Modules : In cases of severe board damage, some technicians use a 5-wire STR module ILPI-354 V

  1. Measure resistance from VCC (pin 7) to GND (should be >1kΩ). If low, check C4 for short.
  2. Disconnect the MOSFET gate (pin 6). If VCC stabilizes (~16V), the MOSFET or current sense is faulty.
  3. Verify R10 (current sense) is not open or drifted high.

If your monitor fails to power on or shows a flickering screen, the ILPI-354 board is often the culprit due to heat exposure and component aging. Measure resistance from VCC (pin 7) to GND

The Update: What Changed in the Schematic (Rev 2.x)

A:

Some clones omit pin 8 internally. In that case, do not rely on external 5V; use a separate 7805 regulator.

External Battery Mod:

Increasing the capacity by soldering heavy-duty wiring to an external, larger capacity 12V12 cap V battery for longer runtimes. 4. Common Repair Focus
