Hi.
I am working on repairing a consumer power supply 110V have a challenge identifying one part photo attached. It reads short which made me think it was an inductor 55uH but the circuit board shows it as a zener diode which I thought might be 1N55H. It is wired in reverse from the control pin of the chip (Gate) and the positive winding of the transformer secondary.

I’d appreciate any help.
The board markings definitely indicate a diode, but it does look like an inductor to me. If it helps at all, I found a datasheet online for the MIP2E4D showing the following schematic. Of course, designers don’t always follow the schematics provided exactly, so yours may vary, but perhaps this might help a bit.
Edit: Upon further inspection, it may not be exclusively for the MIP2E4D.
Thanks David. I also thought it was an inductor but someone on Badcaps.net knew it was a Sony device and the part number of the component a MAZ 4150 15v Zener diode. I replaced it and the supply works.

Excellent! Great to hear you got it working!
