Before inspecting the schematic routing, match the physical markings on your printed circuit board (PCB) with the standard technical manufacturing identifiers to ensure exact revision alignment. ILPI-354 / ILPI-354 V.A (Version A) Common Part Numbers (P/Ns): 790JW1400601R00 790JX1400603R00 491A011H1400H03 / 491A011H1400H06
At the heart of the schematic is the Pulse-Width Modulation (PWM) controller IC paired alongside a heavy-duty power MOSFET. The PWM controller pulses the gate of the MOSFET to high frequencies (typically 50kHz to 100kHz). This action chops the high-voltage DC across the primary winding of the main flyback isolation transformer. 3. The Secondary Rectification & LED Driver Stage
Typically manufactured by TPV (Top Victory Electronics) for Dell. Ilpi-354 V.a Schematic
Before replacing parts blindly, verify values against these standard component parameters:
The is a common power supply board found in several Dell monitors , including the E2316H, SE2216HV, and E1916HV. Finding a complete, official schematic for this specific board can be challenging, as they are often proprietary to the manufacturer, but technicians frequently share circuit details for common repair issues like LED backlight failure. Before inspecting the schematic routing, match the physical
ILPI-354 V.A is a foundational internal power supply and LED driver board designed specifically for mainstream . It provides critical AC-to-DC power conversion and backend LED backlight voltage regulation. This highly specialized board is most notably deployed inside models such as the Dell E2216HV, SE2216H , SE2218HV, E1916HV, and E2316HF.
What (like a multimeter) do you have accessible to probe the circuit rails? This action chops the high-voltage DC across the
Works with the controller to manage power flow. B. Secondary Side (Low Voltage & Backlight)
If you are currently troubleshooting a broken monitor board, let me know it is presenting (e.g., ticking sounds, no power light, screen flash) or what voltages you have measured on the secondary connector so we can pinpoint the faulty component together! Share public link
While a single PDF schematic is hard to come by, the board follows a standard architecture: 1. The Hot Side (Primary Circuit) Input: Accepts 100-240V AC.
