It's worth it to at least give it a try repairing those boards yourself.
Hopefully you have a decent capacitor ESR meter to find bad electrolytic
capacitors. Mine paid for itself the first week.

You can usually recognize bad caps from their brand names, bulging/broken
vents, and the nature of the circuit in which they are employed. E.g.,
with high temperatures and high ripple currents that lead to internal
heating.

Caps are cheap (more or less). I've seen folks selectively replace only
the "defective" caps on a board. Where's the logic in that? Do you think
the others are less likely to fail or will somehow be more convenient to
replace at a later date?
