4. Remove the two nuts and washers securing the touchscreen controller to the game and re-

move the controller from the mounting screws. Then disconnect the touchscreen controller

cable from the back of the controller and disconnect the Molex connector (orange and gray

wires) running from the touchscreen controller cable to the main power harness.

5. Remove the black poly tape from around the edges of the old touchscreen. Remember how

the tape was placed in order to tape the new touchscreen.

6. Use dental floss to carefully cut the foam tape holding the touchscreen to the picture tube until

you are able to completely remove the touchscreen.

7. Remove any remaining adhesive residue with denatured alcohol, then wipe the surface of the

picture tube with the supplied alcohol wipe.

Touchscreen Installation

1. Clean the reverse side of the replacement touchscreen with the supplied alcohol wipe.

2. If there is no tape already on the screen, cut pieces of the supplied 1/2” double-sided foam tape

long enough to cover each edge of the screen without overlapping. After the tape is in place on

the screen, peel off the backing.

3. Replace the new touchscreen over the picture tube (with the cable on the right if you are facing

the game), making sure the screen is properly and evenly aligned over the picture tube. Then

clean the front of the screen with the supplied alcohol wipe.

4. Remembering the manner in which the tape was placed around the touchscreen you removed,

place and cut a length of the supplied black poly tape evenly over an entire edge of the touch-

screen and repeat until all 4 edges are covered.

5. Place and cut a longer length of black poly tape around all 4 edges of the screen.

6. Route the new touchscreen controller cable under the picture tube and away from the flyback

transformer. Then reconnect the cable in the back of the controller and secure the controller on

the mounting screws in the game with the existing hardware. Also connect the Molex connec-

tor (orange and gray wires) to the main power harness.

NOTE: Use the supplied roll of 3/8” foam tape (the thicker of the two 3/8” rolls) if you need to

replace the gasket on the inside of the front bezel. Be sure to remove all of the existing foam

tape and adhesive first.

7. After replacing the front bezel, install the lid on the chassis, connecting the fan power connec-

tor, monitor control board, ground strap, and plastic drain tube. Then pull the lid towards you

until the spring-loaded levers lock into place. See Figures 1 and 2 for locations.

8. Close and lock the lid.

9. Plug in and turn on the game.

10. When the game is finshed booting, calibrate the touchscreen.

11. Replace and lock the coin box or coin box/bill acceptor assembly.
