Once you have the box open, you have to remove the circuit board to access the solder joints.
Carefully disassemble these corner supports by pressing the center pins out of them.
Then squeeze the end of the support to slide it out.
My three cracked joints connected this component to the circuit board.
I used a butane soldering iron, It lets me hold close to the tip and there's no cord in the way.

Well done, excellent tutorial.
Cracked or "cold" solder joints are the most frequent failures on any PC board!
