Intermittent VCC or current sense noise.
Often connected to the Positive (+) side of the large filter capacitor (300V–400V DC) to initiate the switching process. Common Components on the ILPI-354 VA ilpi354 va schematic upd
(For a visual diagram, search “ILPI354 VA schematic UPD” in image search – but here’s a descriptive layout) Intermittent VCC or current sense noise
The board converts AC power into several DC rails. The "VA" part of the schematic likely tracks the or secondary voltages like required for the video scaler and logic circuits. Soft Start Feature: Many of these boards include a soft start circuit ilpi354 va schematic upd
