Shek, how about emailing me if you need help with the soldering. It is not difficult, but a detail which was unique in my experience is that there are traces on both sides of the circuit board; and the capacitor looks as if it needs to be soldered on both sides. That is, one lead from the cap solders to a trace on one side and the other lead solders to a trace on the other side.

Additional note: these electrolytic caps have a "+" and "-" terminal. The "-" terminal is marked, the other is not. Observe the polarity of the old cap before you remove it and be sure to match polarity with the replacement.
