"Bad Caps" can cause all sorts of quirky electronics problems. Sometimes these are the Gremlin or "Ghost in the machine" that cause funky problems. You can sometimes hear them "whistling" high pitched screams. Kind of like an electronic banshee signaling the demiss of your favorite piece of electronics.
