Schematic — Zd-95-g-f

Look for a wide PCB track going to one pin of the main power inductor or the positive terminal of the LED load. This pin will also connect to the anode of the freewheeling diode. It should not have continuity to GND.

The large "bulk" electrolytic capacitor is a common failure point. Check for bulging or leakage. 3. Secondary Output Stage zd-95-g-f schematic
