Ilpi354 Va Schematic Updated Free May 2026

The ILPI-354 power supply board is commonly found in older 22-inch LCD monitors, specifically models from Acer (like the AL2216W) and BenQ. Updated repair guides and blog posts typically focus on resolving the common "no power" or "screen flicker" issues caused by aging components. 🛠️ Common Hardware Failures

Let’s clear up the confusion.

Optocoupler & TL431: These components handle the feedback loop. If the output voltage is "pumping" or unstable, the schematic will show you the resistor divider network connected to the TL431. Check these resistors for value drift. The ILPI-354 power supply board is commonly found

Voltage Rails: The board typically outputs 5V for the logic board and a variable higher voltage (often around 17V-20V) for the LED backlight string. Technical Resources

• Observation: The updated schematic highlights the PFC controller IC (often a standard 8-pin SMD package). The output voltage is regulated at approximately 380V–400V DC. Technicians using older schematics often expected 390V, but the updated diagrams show tighter tolerances, noting that a drop below 360V here will inhibit the main relay or the startup sequence.
