Wannien 101v0 Power Supply Schematic Exclusive

The auxiliary winding capacitor (C22 on the schematic) is the #1 failure point. When it dries out (typically after 2-3 years), the controller loses bias voltage, causing the supply to "hiccup" (start, stop, start, stop).

Disclaimer: This report is based on technical analysis of similar SMPS modules and standard industry practices for "Wannien" branded electronics. High voltage is present inside power supplies; exercise extreme caution if probing live circuits.
