There is a simpler trick: get a  tool that allows  to heat or cool the
caps. This could be:
 - a hair dryer or heat gun
 - your soldering iron
 - a candle or a lighter/matches if used with care
 - cold spray
try to heat/cool any suspect cap and see if the problem changes.
If it does, you found a bad cap.
