OK, That's what I was thinking originally as well, but there don't seem to be any capacitors that appear to be bulging or anything that I can see of, but then again I guess an electrolytic doesn't always have to fail by venting...
How can I test if an electrolytic has failed or not? I'm asking because my ESR tester isn't working anymore for some reason (it reads "no or unknown part" everytime I attach an electrolytic capacitor to it, even known good ones).
Any particular values of capacitors that I should look out for that are known to be trouble prone in these things?
