My roommate's LED lights went out, and she traced it down to a bad wallwart. I thought I'd crack it open and see if there's any (electronic) gore.
Nothing on the trace-side of the PCB, nothing seems to have gotten super hot and burnt, unlike that last power supply I opened

And the top looks okay too, except maybe that cap on the left that's clearly on the way out.

(You may spot something else wrong. Hang on to that)

@foone Bulging cap on the left?

Back in the 90s I had an Ethernet card go out on me. Quick visual of it revealed nothing. Sniff test showed me where something had smoked that I didn’t notice the first time.

Hard to do these days with more highly integrated circuits and fewer tiny surface mount devices (well, on systems that have been mass produced for more than a few revs). (1/2)

@foone It’s not a very good test anyhow. 🤣
