First check continuity between the spot in the red circle, and the orange dot to the right of it. Press the button and make sure the value goes close to 0ohms when pressed. Just becasue those buttons 'click' when pressed does not mean they are good.
If the button tests good, then solder a jumper wire and connect the 2 Orange spots. Also make sure the solder joint in the Red circle is good making connection to that trace there.
