The secondary rail splits off into two sub-systems: raw power delivery and digital sensing. Wlx-896b Schematic
Remember: every component on that board has a purpose, and the schematic tells its story. Happy repairing. during testing
If the unit is completely dead (no display), the primary side switching IC or the startup resistor is likely failed. Documentation Links 50-60Hz (Universal wide-voltage range).
