It has been a while for me, but once you make sure that the magnet is in the up position, and after you remove the backglass, I suggest laying the upper playfield on the main playfield glass and the connections should be obvious.

There is a clip that holds it from being swiveled forward at the top.

Good luck.

I honestly don't remember, but those screws look like they could be easily removed in order to get the PF off the hinge.

At the bottom of the plate pictured isn't that slot where the hinge post could slip through?
