If you're missing a single line the vast majority of the time it's a break in the connection at the glass.

Take something pointed and non-conductive and push in on the area where the connection is while the game is on.
I use orangewood sticks (I've covered these in my soldering guide) or you could fashion something out of a wooden skewer.
The pin you have marked slides between two sheets of glass (at the top after the 90 degree bend) and presses against a copper pad. You will need to expose the copper pad and then epoxy the pin to the pad.
Quoted from mof:It works!
It sure took a while, but it was a fun fix. I hope it holds!
Now to cure the epoxy at 149F for 60 minutes...

Congratulations. That's a delicate repair.
