Service instructions for removing and installing the 15" monitor in the Megatouch Ion eVo, eVo Wallette, and Elite Edge games, including dongle socket and cable handling.
Monitor Removal
1. Turn off and unplug the game.
2. Place something in front of the game to brace the bezel once the strain relief cord is undone,
then unlock and open the CPU section.
3. Remove the screw and washer fastening the strain relief cord, then remove the remaining 5
screws fastening the LCD mounting bracket to the game. The dongle socket ground wire will
also be removed in the process. See Figure 1.
4. Remove the nut, wire and bolt from the dongle socket assembly located on LCD mounting
bracket, then remove the bracket. See Figure 1.
5. Carefully cut the tie wraps around the VGA monitor cable and remove the ground wire. Dis-
connect the cable from the monitor and the motherboard. See Figure 1. Unscrew the bracket
on the underside of the I/O board to release the cable.
6. Remove the OSD cable from the twist clamp and disconnect it from the OSD board and the
monitor. Then remove the OSD board from the Velcro attached to the back of the monitor and
set it aside. See Figure 1.
7. Disconnect the LCD power connector (black and yellow wires). See Figure 2.
8. Carefully cut the tie wrap around the touchscreen controller cable and disconnect the cable
from the touchscreen controller. Also remove the ground wire. See Figure 1.
9. Disconnect the touchscreen power cable from the touchscreen controller (See Figure 1), then
disconnect the Molex connector identified by the orange and gray wires.
10. Loosen the 6 screws (3 per hinge) on the monitor side of the hinges in order to raise the hinges
and allow room to remove the monitor. See Figure 2.
NOTE: Elite Edge games may require you to remove the joystick in order to allow the neces-
sary room for loosening of the hinge screws. To remove the joystick, carefully place the game
on its side. Remove the 2 screws securing the protective bracket on the bottom of the game
and remove the bracket. Disconnect the joystick connector and remove the joystick. Return
the game to its upright position.
11. Slide the monitor out of the bezel.
12. If you will not be reusing the existing touchscreen, continue with installing the new monitor. If
you will be reusing the touchscreen, note the orientation of the screen (i.e., the positioning of
the ribbon cable and which side is the front) before removing it from the monitor. Then use
dental floss to carefully cut the foam tape holding the screen to the monitor. Once the
touchscreen is completely free from the monitor, remove any residual foam tape from the
screen with denatured alcohol and clean the glass with the supplied alcohol wipe.
Monitor Installation
1. If you will not be using the touchscreen from your original monitor, skip to step 3. If you will be
using the original touchscreen, clean the glass on the new LCD monitor with the supplied
alcohol wipe, then cut pieces of the supplied 1/2” foam tape long enough to cover each edge of
the monitor without overlapping. After the tape is in place on the monitor, peel off the backing.
2. Carefully place the touchscreen over the monitor in the same manner it was attached to the old

monitor, making sure the screen is properly and evenly aligned over the glass. Clean the front
of the touchscreen with the supplied alcohol wipe once it is in place.
3. Carefully slide the new monitor into the bezel, making certain that the white edge of the
monitor and the monitor wire connections are facing the bottom of the bezel. Ensure that the
monitor is properly centered, then tighten the hinge screws. See Figure 2.
NOTE: If you removed the joystick on your Elite Edge, carefully return the game to its side and
reconnect the joystick to the connector in the game. Place the protective bracket in its previous
position, sliding it under the lazy Susan and making sure the cutouts are placed around the
installed screws. Make sure all wires are secured inside the bracket, then reinstall the 2
screws securing the bracket. Return the game to its upright position.
4. Install the supplied LCD mounting bracket and fasten it to the game with the 6 screws. One
screw (and washer) will fasten the strain relief cord, while another will secure the blue ground
wire for the dongle socket. See Figure 1.
5. Replace the dongle socket assembly by securing the bolt, green wire and nut over the LCD
mounting bracket. See Figure 1.
6. Connect the touchscreen controller cable to the touchscreen controller and secure it with a tie
wrap. Also restore the touchscreen controller cable ground wire. See Figure 1.
7. Connect the touchscreen power cable to the touchscreen controller (See Figure 1) and recon-
nect the Molex connector (orange and gray wires).
8. Connect the LCD power connector (black and yellow wires). See Figure 2.
9. Reattach the OSD board to the Velcro on the back of the monitor, then connect the new OSD
cable to both the OSD board and the monitor. See Figure 1. Secure the cable in the twist
clamp.
10. Connect the new VGA cable to both the monitor and the motherboard. Run the cable beneath
the I/O board mounting plate and secure it in place with the bracket and 2 screws. See Figure
8. Also replace the ground wire.
11. Tie wrap the VGA monitor cable and the OSD cable.
