This is a well known problem among TV repairmen (my
brother is one).
Early failure of electroytics is becoming increasingly common. I've
had to replace about half of them in my vcr power supply and it's only
5 years old! OTOH I'm using a 40-year old radio where they are still
in good order...
Early tantalums are another problem area. If one goes, replace them
all.
I would not fret too much about these bum capacitors - in a few years
they will pretty much be out of the market and into the trash.
Since the dawn of (electronics) time, there have been infestations of
poorly made, sometimes counterfeit electronics parts, that foul up the
industry for awhile. Nothing changes.
