You cannot just look for the bugling cap and/or electrolyte leaking physical symptoms of bad/failed caps. One needs a quality ESR meter to drill down as to whether or not a cap is indeed open/shorted/leaking/defective. A companion tester would be one of the old school 20-600VDC out of circuit leakage testers. Too many people these days are getting wrapped around the troubleshooting "axel" just looking for physical evidence of failures in this regard (IMHO); test do not guess is one of my favorite motto's.
