Locate capacitors C17, C26, C19, C28

Remove the capacitors. It may help to cut off the body of the capacitor 
with wire cutters so each leg can be removed individually.

Clear the solder from the round positive pads of each capacitor. (The 
square pads marked with more white ink is the negative one)
