Update 10/27: A few readers have pointed out to me that it's likely a bad capacitor, which cap it is, and how to test that and/or fix it! When troubleshooting old electronics, rule #1 is "check the caps". Electrolytic capacitors are the most common failure item in solid-state devices. This alarm clock predates the infamous capacitor plague but the finite and somewhat short lifespan of electrolytics has been known since their invention.

> which cap it is One of my led wall lamp died. I opened the driver/transformer and has a very suspictious capacitor with a curved top. Anyway, I just bought a $3 driver replacement in front of my home. (I'm bad at soldering, so I'd probably need a whole afternoon to try to fix it).
