What makes these things one day just not work anymore?

One sure way to find out is to take it apart, and do a post-mortem.

lol I cracked the case open and once I saw the transformer it can't be worth it to mess with it, besides the cable was too short.

If you already opened it up, it shouldn't be much extra work to measure the windings, and if they are good, measure the other parts (rectifiers and probably one or two caps).

Buzz out the winding to see which one is open, primary or secondary,

You said this was a DC wall wart - where is the bridge rectifier and filter cap?
