I am not too surprised to hear this. It could well have been bad from day 1.

That would surely be the next thing. I envisioned this set as a portable,
but it must be something a bit bigger than that since it has a cooling fan.
There's no excuse other than cheapness as to why these fans fail.

(Seriously. I have computer fans that were made in 1987 and are still going
strong.)

That seems like a pretty common outcome...the circuit works fine until one
day the capacitor really gives it up. Somehow it struggles along, maybe due
to reserves in the design? Sometimes other components fail when the
capacitor stops working, but in this case, it sounds like the unit has been
restored to perfect health.
