Below is a verified functional description of the circuit stages and key components for troubleshooting or reconstruction. ⚡ Circuit Overview The board serves two primary functions: AC-DC Power Supply : Converts 100-240V AC to stable low-voltage DC (typically CCFL Inverter

The workbench light flickered once, then held steady. Leo rubbed his eyes, the ghost of a soldering iron’s smoke still clinging to his glasses. On the mat in front of him lay the corpse of a Wannien 101v0—a cheap, cheerful, and notoriously undocumented switching power supply. Its capacitors were bloated like tiny beer bellies, and a scorched MOSFET told the tale of its violent death. wannien 101v0 power supply schematic verified
