On the right side of the motherboard there is a coin shaped capacitor. In picture two you can see a detailed view of the capacitor (5.5V 0.22F).

Note which polarity of the capacitor is facing which side on a piece of paper.

You can find the + and - Symbols on the legs of the capacitor.

Remove the capacitor.

The Brother technician used side cutters to remove the defect capacitor.

Be careful to LEAVE ENOUGH OF THE WIRE to be able to solder a new capacitor onto them.

Looking at you piece of paper, solder the new capacitor in THE RIGHT DIRECTION (POLARITY) to the remaining wires from the removed capacitor.
