No video, but here are the exact steps for removing the upper playfield:
With playfield lifted, disconnect the 2 blue network cables from the main board and the white 5 pin and white 4 pin plugs (solenoid power) from the z-connectors. Label the blue network cables if they are not already - one is for switches, the other leds.
Clip any wire ties that would prevent the disconnected wires from feeding into the lower playfield cutout.
Lower the playfield.
Remove stone wall from front of upper playfield (2 wood screws).
Remove mystery machine (2 wood screws) and disconnect network cable from inside van.
Remove orange wireform (1 screw).
Remove UPPER purple wireform (1 11/32 nut).
Remove blue wireform (1 11/32 nut).
Remove the large upper playfield plastic (3 5/16 nuts).
Remove 2 square head wood screws on right side of upper playfield now exposed by removing large plastic.
Unplug and remove left spotlight (1 screw and 1 hexpost).
Remove leftmost plastic (3 5/16 nuts) to allow for easier removal of screws in next step.
Remove 2 ¼ wood screws from left woodrail on lower playfield (frees the bracket holding up the left side of upper playfield).
Remove topmost plastic and cut zip tie (3 machine screws).
Remove entrance gate (1 5/16 nut) and plastic post (1 ¼ post screw) – this will allow the guide rail to flex backwards in order to clear the entrance ramp when removing.
Remove 2 entrance ramp screws.
Carefully lift front of upper playfield slightly to separate, then gently pull forward to clear the entrance ramp.
Feed disconnected wires up through lower playfield cutout and you should be free!
