Based on the , keeping these components on hand will fix 90% of ILPI-354 failures: Fuse: 250V 3.15A or 4A (slow blow) Capacitors: 1000uF 16V/25V (Low ESR) Capacitors: 47uF 50V Bridge Rectifier: 2A/600V or 4A/600V ilpi354 va schematic updated

: Full-wave bridge rectifier diodes, primary bulk filter capacitor (typically rated at 68µF to 100µF, 450V), Pulse Width Modulation (PWM) controller IC, and an integrated high-voltage power MOSFET. The specific you are currently observing

: Affix a validated replacement ILPI-354 V.A board. Seat all internal wiring assemblies firmly back into their structural slots. Seat all internal wiring assemblies firmly back into

Low-voltage DC (typically 5V and 3.3V rails) used to power the monitor's logic/driver board (such as the companion ILIF-460 V.A or ILIF-473 V.A processing units).

Check continuity across the main input fuse. A completely open fuse implies a catastrophic short further down the circuit line.
