it looks like a couple of capacitors(?) I have on the board have burst and I was wondering if you could help me identify them so I can replace them. I've attached a picture which contains both of the blown components; one is almost directly in the middle of the picture and the other is up about an inch or two from the one in the center at approximately 10 o'clock. They both have "S533" printed on them but nothing else.

Any help you can provide would be much appreciated....
