You should look for outward signs of a blown capacitor, while a bad cap may not always show signs
they usually do. In this case C13 (right side of picture) was the culprit. Look at the tops of all the
other caps and you can see they are all FLAT. Now look at C13, it has clearly swelled up and the top
is visibly “domed” upward. Also look for signs or leakage, brown spots on the cap or the board.
I will jump ahead just a little here so you can get a good idea of what to look for. These are the two
caps that were removed; on the left is C14 with the normal “flat” top. In the center is C13 with its
swollen and “domed” top. Even though there were no signs of leakage at first, once removed you can
see that the bottom of the capacitor was indeed leaking. (Picture on the right)
