Probably not. That is the main filter cap. Most likely it is one of the smaller caps. Look for white corrosion an the base of all of the caps. Since they are electrolytic caps, they either leak on to the board or dry up. You can test every cap or replace them all. I think they are switching power supplies therefore the tolerances of the caps is critical.
