Just replace the visibly bad caps, and you're 90% sure to be good to
go. No test equipment needed other than your eyeballs. And, in
general, the caps only have to be close in value (but do not go lower
in voltage rating). I've fixed loads of these - very few have anything
wrong other than bad caps in the backlight supply.

If you have a good supply of caps, it's a good idea to replace all the
similar ones, not just those that are already bulging. The rest are
likely to follow soon.
