I don't like to waste time with these things. If I see one dodgy
electrolytic, I do the lot (at least of that size/value/voltage).
And if some 'genius' has used one as the timing capacitor on a one-shot,
you've probably just introduced a fault by replacing it (if the original
one was still OK)... Not a problem in most PSUs, I'll admit.
You still need the ESR meter to prove you had a capacitor problem in the
first place, of course.

Assuming this is an electronic problem, I would first
test all the
electrolytics on an ESR meter. High-ESR capacitors cause the most odd
faults on SMPUSs...
I'll need to find one...
