The ILPI-354 V.A is a power supply board primarily used in several Dell LED-backlit LCD monitors. It functions as the "heart" of the display, converting external power into the specific voltages required by the internal circuits to ensure normal operation. Compatible Monitor Models

Key Updates to Note:

  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.
