Ilpi354 Va Schematic Updated May 2026

The ILPI-354 V.A is a common power supply board used in several Dell monitors, including the E1916HV, E2016, SE2216H, and SE2218HV.

While a full high-resolution "updated" schematic PDF is rarely hosted on public social posts, technical forums and repair communities identify the following key specifications and common repair points for this board: Board Overview & Compatibility

Part Numbers: Often labeled as 491A011H1400H03 or 491A011H1400H05.

Integrated Functions: The board combines the Power Supply Unit (PSU) and the LED Driver for the backlight. Compatible Models: Dell E-Series: E1916HV, E2016, E2216HV, E2316H. Dell SE-Series: SE2216H, SE2218HV, SE2219H. Common Technical Issues ilpi354 va schematic updated

Repair logs on Monitor Forums (forum-monitor.net.ru) and similar communities highlight these common failure points:

No Power / Dead Monitor: Often caused by a failure in the primary side switching section or a blown fuse.

Backlight Failure: The LED driver section (managed by IC601 on some revisions) may fail, causing the screen to remain black while the power LED is on. The ILPI-354 V

Voltage Instability: Replacing the entire board is often recommended over component-level repair because of the low cost of replacement units on sites like AliExpress and eBay . Search for Schematics

Downloading and Using the Updated Schematic

When searching for the file, avoid generic schematic databases that host the outdated 2008 version. Look for these identifiers in the file name or header:

• Filename: LG_ILPI354_VA_REV2.3_SCH.pdf
• Header text: "POWER SUPPLY FOR 32/37/42 INCH LCD"
• Date stamp: After 2015 (Older ones have 2009-2011 errors).

Key Fixes in the Updated Schematic

| Area | Original Issue | v2.2 Update | |------|----------------|--------------| | Primary Side | Missing startup resistor (R013) | Clearly labeled as 470kΩ, 1% | | PWM Controller | IC901 pin 5 (VCC) mislabeled | Corrected to 18V input from auxiliary winding | | Backlight Section | Omitted LED current sense resistors | Added R321, R322 (2.2Ω each) | | Protection Circuit | No OVP (over-voltage) threshold | Now shows 32V trigger point |
