Counterintuitively, it still might be worth it. If the power supplies which come with new lights are crappy and tend to fail long before the lights, it might make sense to buy a decent quality one separately, even if it costs more than a new set.

madires:
Of course, the wall warts included are usually of the cheap variety. If you replace them with a good quality one you might need to change the connectors. The lights have a modified DIN speaker connector.

A bit difficult to see, but some of the solder joints
could be suspect (cracked?). No expert, but maybe
you could test the green capacitor?

Took some more pictures on the sides:

I'll test the capacitors soon.
