Why Capacitors go bad

<< weird when I first saw this post there was no picture of described condensor so I assumed we were talking electronics.sorry to muddy the waters!>>

capacitors dry out. The dielectric dope in them just dries out then they short internally and blow their tops...literally. They are like foil and wax paper wrapped in a roll, eventually the foil shorts to the other foil layer. See the swollen tops? Find a non-op flat screen TV and I can almost guarantee there are a few of these on the power board, .50 a piece.
