Stop measuring voltage on the ILPI354 pins directly. The pitch is 0.5mm—one slip of the probe and you short VREG5 to GND, killing the IC instantly.
provide community-verified component values and pinouts for the ILPI series. ilpi354 va schematic updated
The is more than just a PDF file; it is a diagnostic bible that saves hours of guesswork. By following the corrected resistor values, understanding the revised snubber networks, and respecting the updated component ratings, you can repair boards that others throw into the e-waste bin.

: Provides the necessary voltage (VLED+) to the backlight strips. The is more than just a PDF file;
If the backlight flashes and goes out, the ILPI-354 VA protection circuit is likely tripping due to a bad lamp or a faulty inverter transformer.
