Ilpi-354 — V.a Schematic
The lifeblood of the Ilpi-354 V.a lies in its power regulation. The schematic reveals a robust linear power supply design, typical of the era in which this unit was conceived.
Technicians frequently encounter "no power" issues related to this board. Key components to inspect during troubleshooting include: POWER SUPPLY - NETZTEIL - ALIMENTAZIONE Ilpi-354 V.a Schematic

What are the the monitor is showing (e.g., dead, flashing green light, screen goes black after 2 seconds)? Do you have access to a multimeter or an ESR meter ? The lifeblood of the Ilpi-354 V
Boosts voltage to the required level to drive the monitor's LED backlight string. Compatible Monitor Models flashing green light
Remember that the high-voltage primary side is lethal. Always use an isolation transformer and discharge the bulk capacitor (C5) through a resistor (e.g., 10kΩ 5W) before probing. With the Ilpi-354 V.a schematic in hand and the systematic approach outlined above, you can rescue valuable industrial electronics from the scrap heap and restore them to factory specifications.
