Ilpi354 Va Schematic Updated ((full))

Widely found in Dell E-series monitors ranging from 19 to 23 inches. Schematic Details & Architecture

After the standby runs, the main relay (RL101) should click, and the PFC should boost voltage to ~390V. If you see only 330V (rectified mains), the updated schematic points to a new suspect: (PFC output voltage dividers).

[ V_OUT = 1V \times (1 + \fracR1R2) ]

No 3V/5V rail = No power = Dead laptop.

The ILPI-354 V.A is an integrated power supply and LED driver board (PCB #491A011H1400H03) used in several Dell E-Series and SE-Series monitors, including the E2016HL and SE2218HV. The circuit features a primary switching stage, typically utilizing components like the LD75xx or OBxxxx PWM ICs, and a secondary stage providing +5V and +12V/19V outputs. Technical documentation, including schematics and board layouts for repair, can be found via resources like AliExpress

: Converts AC input to DC; standard troubleshooting involves checking for continuity across its pins. Common Failure Points Blown Fuses [ V_OUT = 1V \times (1 + \fracR1R2)

: 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

: Provides the necessary voltage (VLED+) to the backlight strips.

First, a reality check. is rarely the primary component number. It is usually a marking code (top mark) on a smaller IC.
