Over years of thermal cycling, secondary electrolytic caps dry out or bulge at the top vent seals. Swapping out degrading capacitors on the 5V or backlight lines with low-ESR equivalents commonly fixes standby looping.
The ILPI354 VA schematic has been updated to improve power delivery and simplify layout for modular LED driver applications. ilpi354 va schematic updated
Use the schematic to find the VCC pin of the PWM controller. If this IC isn’t getting power (usually around 12V–15V), the board won't start. 2. Voltage Fluctuations Over years of thermal cycling, secondary electrolytic caps
Elevate base DC rails to the needed forward voltage required by the monitor's specific LED screen configuration. ⚡ Critical Failure Modes & Repair Guide Use the schematic to find the VCC pin of the PWM controller

Whether you are a long-time follower of the project or just tuning in, this update brings the design one step closer to finalization.
