: Under normal operation, the voltage to the LED strips typically jumps to around 40V .
Locate the secondary diodes leading to the output connector. The typical output for this board is 5V (logic) and a higher voltage, typically over 16V , for the LED driver.
The ILPI-354 power board is the central power supply module for several popular Dell monitor models, including the , E2216HV , SE2216H , SE2218 , E1916HV , and E2316HF . If you experience sudden blackouts, blinking screens, or complete power failure on any of these models, it is highly likely that the ILPI-354 power board is the culprit.
Before touching your soldering iron, it is helpful to match the monitor's behavior with the most probable component failure. Ilpi-354 V.a Schematic
The is an internal power supply and LED driver combo board manufactured for popular budget-friendly Dell monitors. Understanding its schematic layout is critical for component-level repair, especially when troubleshooting common display failures like lack of power or backlight loss.
: If the DP860EGN chip is unavailable, seasoned technicians map it directly to the highly compatible OZ9998BGN chip, which features an identical pinout configuration. The Secondary Connector Pinout

Inspect the solder joints around the inverter transformer and the CCFL connector pins. The high voltage and heat can cause the solder to crystallize and crack over time. Resoldering these joints often cures the problem. Safety Warnings
Measure continuity across the main fuse. Test for a shorted bridge rectifier diode. Blown main fuse immediately upon replacement. Short-circuited Power MOSFET.
: It is frequently used for repairing monitors like the LG Flatron W2242S and Philips 220CW , where this specific board is the core power and inverter module. The ILPI-354 power board is the central power
The is a widely used power supply and LED driver board found in several Dell LED monitors, including popular models like the Dell E2216HV, SE2216H, and SE2218HV. It acts as the "heart" of the monitor, converting AC mains voltage into the stable DC voltages needed by the screen's internal logic and backlight system.
