Answers :

Any bulged capacitor is a failed capacitor. The nice-looking ones next to the bulged ones have failed too since they are in the same circuit.
The real fix is to replace ALL the Electrolytic capacitors. You can use ones with slightly higher voltage ratings without problems provided that they will fit.You can use two 470's to replace a 1000 provided you can fit them in.
There may also be a 47mf/25 volt cap off to itself. Replace it too, if it fails, the unit will just not come on at all.
