Mid Trim Panel

The mid trim panel is fabricated from sheet steel. The function of the trim is to act as
a strengthening brace for the door assembly and to provide an area for the
playbuttons and coin entry to be mounted.
The mid trim panel is fitted with a "drop-in" playbutton panel and is attached to the
door assembly by studs and screws. It can be removed from the door for repair or
replacement.
Game conversions require the "drop-in" panel be replaced to accommodate different
playbutton configurations. This panel is secured to the mid trim by four nuts fitted to
studs. These nuts are accessed from the underside of the mid trim.
Removal and Replacement Procedures:
To remove the mid trim panel from the door of the machine:
1. Open the cabinet door, and switch OFF the machine.
2. Remove the reflector panel from inside the door:
Remove the four screws that secure the panel to the right-hand door side,
•
nearest the hinge at the base of the door and behind the coin comparator.
Disconnect the looms to the coin comparator and the fluorescent ballast.
•
Press down on the panel to disengage from under the coin entry slot on the
•
door mid trim.
•
Carefully remove the reflector panel from its locating slots.
3. Unplug all of the playbutton microswitches from the playbutton bodies (see
Playbuttons in this chapter). Mark each switch for easy identification.
4. Remove the screws on either side of the mid trim panel that attach it to the
door.
5. Pull the mid trim panel from the door.
Replacement is a reversal of the removal procedure.

Playbuttons

The playbuttons function as the interface between the player and the machine.
Various games have different configurations of playbuttons, and the playbuttons
themselves may vary from game to game, or from market to market. The playbuttons
are mounted onto the "drop-in" panel.
Removal and Replacement Procedures:
To replace a playbutton lamp (refer to Figure 4-7):
1. Open the cabinet door, and switch OFF the machine.
2. Grasp the microswitch and lamp holder unit and pull it down, out of the body of
the playbutton.
3. Pull out the faulty lamp, and push in the replacement lamp.
