Hi Chris,
It seems that the problem is related to getting contact right away.
I would check on the following:
(1) The position of the metal plates. Did they maybe change? I would make sure that these metal plates are really good fastened on the side of the circuit board where there are no circuits (the side you see on picture 3).
(2) Before fixing the metal plates, however, I would lift them and would clean the area beneath, so that the plates actually hit the area/dot on the circuit board where they supposed to hit it. You can clean that area with isopropyl alcohol and - in addition - also use a soldering iron to carefully "create" a fresh and flat solder point.
