Anybody know/repair the wall wart type power supply/charger part that usually fails? My old LG wall wart power supply gave up the ghost while I was using the monitor it powers. Suddenly the monitor died. I verify zero voltage from the plug that goes into the back of the monitor (used my DMM). I have a stash/parts bin accumulated over decades and am handy with repairing electronics stuff and soldering, but am wondering what usually fails in there. There's the satisfaction of having repaired it myself, but if it's the small IC maybe I'm better off just getting a used unit.
what is the usual cause of a dead power brick?

Electrolytic caps are the usual culprit in a switching power supply. Barring that, a transistor overheating and cooking itself to death.
Either way, wall warts are usually a pain to take apart....they go straight to the trash and get replaced.

How 'bout electronics recycling?
From most accounts, that does more harm that good although NIMBY.
Is my Dell laptop power supply a linear of switching type? CN - 0DF263 - 71615 - 821 - 57F2

If it's ROHS compliant my uncle has said that he's seen arcing on soldering. I've seen capacitors go bad. This happen to my Microwave and was a quick fix.
It's not worth fixing, just replace it.
Yeah - these sort of things generally aren't worth repairing. Some might be repairable, but it's going to be tough.
I had one Lenovo USB-C power supply fail, but I'm not sure what it was. Could have been the brick or possibly a problem with the cable or connector. It was a captive cable rather than one with a port that could accept a separate cable.
