Varistor/fuse is soldered on the Circuit board.  Remove a broken Varistor / Fuse with soldering iron 

and solder brand-new one.  (Fig. 7)

Note: Be sure to use the appropriate parts.

1. If Fuse is broken, Varistor is usually broken by showing the sign of breakage mentioned below.

    In this case, replace fuse and varistor at the same time.

             a) Cracks in the surface of varistor

             b) Black discolored surface of varistor

2. Only 

Varistor can be damaged if Charger is plugged in a power source at double the rated voltage.

    In this case, replace Varistor solely.

3. If Fuse is broken while Varistor is not broken, Circuit board can be broken.

    In this case, replace charging circuit complete.  (Fig. 6)
