Step 3: The PFC Enigma (Why is my main voltage stuck at 330V?)
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: R512 & R513 (PFC output voltage dividers). The ILPI-354 VA is a common power supply
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 If you see only 330V (rectified mains), the
Final Action Item: Before you replace IC501 or IC502, verify every resistor connected to its feedback pin against the updated values. Chances are, a single changed resistor (like R518 or R507) is the only thing standing between a dead board and a perfect 390V PFC output.
