Ilpi-354 V.a Schematic «Top 100 VERIFIED»
The primary reservoir capacitor stores dangerous voltage levels long after the AC cord is pulled. Confirm it drops to 0V with a voltmeter before handling component leads.
Before inspecting the schematic routing, match the physical markings on your printed circuit board (PCB) with the standard technical manufacturing identifiers to ensure exact revision alignment. ILPI-354 / ILPI-354 V.A (Version A) Common Part Numbers (P/Ns): 790JW1400601R00 790JX1400603R00 491A011H1400H03 / 491A011H1400H06
If you lack a dedicated hardware schematic document or specialized soldering equipment to safely debug high-voltage circuitry, swapping the entire power board is highly recommended. Complete replacement units are readily available on online marketplaces like AliExpress. To replace the board: Disconnect all external video and power cables. Ilpi-354 V.a Schematic
Because individual board components like transformers and specific SMD driver ICs can be difficult to source or "nightmares to repair," many technicians recommend a full board replacement.
If you are looking for this schematic for repair purposes, the ILPI-354 is known for a few standard issues: ILPI-354 / ILPI-354 V
LED Driver IC Protection loop, Open-circuit backlight string array
Supplies constant current to the LED backlight strip. Ilpi-354 V.a Schematic
The ILPI-354 V.A power board operates as an internal power regulator. It converts high-voltage alternating current (AC) from a wall outlet into standard low-voltage direct current (DC) rails to power the logic mainboard and the display panel’s LED backlighting.
A documented real-world repair case for the ILPI-354 revealed a hidden problem:
