Re:
Control Board Installation for Megatouch Combo Jukebox and MegaTunes
If you are replacing the control board on a Megatouch Combo Jukebox, you will need to disable the jumper located
at JP8 on the board if there is a jumper at this location. When replacing the control board in a MegaTunes unit, the
jumper must be in place. Also, if you are sending a board in for repair, be sure to remove the I Button from the
board before sending it in and replace it when the board is returned. The I Button should always remain with the
game.
To install the control board in a Megatouch Combo Jukebox:
1. Turn off and unplug the jukebox.
2. Remove the rear door and locate the control board in the unit. It will either be located next to the fluorescent
lamp assembly or next to the single board computer (see Figure 1).
3. Disconnect the antenna and all harnesses from the board. Be sure to note where each connection was made.
4. Remove the screws fastening the board to the unit and remove the board. Then remove the I Button and
replace it in the replacement board. See Figure 2.

5. Using Figure 2, locate JP8 on the new control board.
6. If there is a jumper at this location, remove the jumper from the pins on the control board and replace it so one
of the pins is exposed. This will both disable the jumper and keep it from being misplaced. See Figure 2.
7. Install the new control board in the jukebox in the manner you removed the old board.
8. Reconnect the antenna and all harnesses to the board.
9. Replace the rear door.
10. Plug in and turn on the game.
NOTE: It may be necessary to reprogram the remote control after replacing the control board. See your
owner’s manual for instructions.

replace it in the new board. See Figure 2.
