of the schematic, such as the power distribution or signal processing units?
At the AC input, you will find a fuse, a varistor (MOV) for surge protection, and a network of inductors and X/Y capacitors forming an EMI filter. If the monitor is completely dead with no standby light, this is the first area to check. A blown fuse here almost always points to a shorted bridge rectifier or a shorted main switching MOSFET. The Feedback Loop

I powered up a mystery Ilpi-354 V.a without a schematic once. The main filter cap (63V 4700µF) exploded after 10 seconds — the previous owner had swapped in a 40V cap by mistake. Always measure DC resistance across the rails before applying power. : From what I can gather, the Ilpi-354 V
Primary side failure (fuse blown, dead MOSFET, or faulty PWM IC).
: Enable pin (3V logic signal sent from the mainboard to wake the backlight driver).
Driven by a Pulse-Width Modulation (PWM) controller IC and a high-voltage power MOSFET (sometimes integrated into a single chip like a Fairchild/OnSemi Power Switch or Power Integrations LinkSwitch chip). This stage rapidly pulses the high-voltage DC across the primary winding of the isolation transformer. 2. Secondary (Cold) Side Circuitry If the monitor is completely dead with no
