What are the the monitor is showing (e.g., dead, flashing green light, screen goes black after 2 seconds)? Do you have access to a multimeter or an ESR meter ?
Working on power supply boards like the ILPI-354 V.A involves dealing with lethal voltages. Ilpi-354 V.a Schematic
Usually arranged in a push-pull or full-bridge configuration to drive the inverter transformer. What are the the monitor is showing (e
If you are using the schematic to repair an ILPI-354 V.A board, several well-known failure modes are worth investigating. flashing green light
Do not just replace the fuse. Check the main switching transistor/MOSFET and the bridge rectifier diodes for shorts. If you replace the fuse without fixing the short, the new fuse will blow immediately.
