| Step 1: |
TURN POWER OFF. UNPLUG GAME. High voltages are present inside the game when plugged in, which can injure or kill. Leave power off, and game unplugged, until work is complete!
|
Step 2:
 |
Unlock backbox and remove backglass to gain access to fluorescent tube and circuit boards inside.
|
Step 3:
 |
Remove old fluorescent tube from it's mounting sockets on either end of the tube. To do this, rotate the tube 1/4 turn, and pull straight out from the sockets.
|
Step 4:
 |
Open insert panel to gain access to circuit boards on back side of panel.
Remove the Squawk & Talk board (far/lower left), and the lamp driver board (far right) to gain access to the screws behind them that hold the fluorescent lamp sockets in place.
You will need a 1/4-inch socket driver to remove the factory-original mounting screws for each board (2 screws per board).
Plastic standoffs will also hold each board in place. Use needle-nose pliers (or similar) to pinch each standoff while you remove the board from it.

|
Step 5:
 |
Using a Phillips screw driver, remove the 2 screws and washers that hold the lamp sockets to the insert panel.
Discard the screws, but keep the washers.
|
Step 6:
 |
Place a washer on one of the new shorter screws that comes in the kit, and install it into the right-side hole (nearest the insert panel hinge).
Secure the lamp socket to the screw on the front side of the insert panel.
The shorter screws for the lamp sockets allow the slightly-larger-diameter LED tube to fit in the sockets properly, without hitting the original long screws.
|
Step 7:
 |
For the left screw hole (farthest from the hinge), use a 9/64-inch drill bit and electric drill to make a new screw hole just to the left of the old screw hole.
About 1/8-inch between the old and new holes is best.
Using the remaining shorter screw from the kit, place a washer on it, and install it into the new hole you drilled for the left-side lamp socket.
Secure the lamp socket to the screw on the front side of the insert panel.
|
Step 8:
 |
Slip one of the 2 warning tags over the new LED tube and install it into the lamp sockets on the front of the insert panel.
Be sure to line up the pins on each end of the tube horizontally so they both slip straight into each socket.
Once in each socket, turn the tube 1/4 turn in either direction to lock it in place in the sockets.
The tube can be installed in either direction (it has no polarity). We recommend installing the tube so that the back masking on the tube is facing AWAY FROM the insert panel. This directs most of the tube's light at the insert panel, but tends to disburse the light more evenly, and illuminate the backglass better, once it's installed and illuminated.
|
Step 9:
 |
Gain access to the power supply in the main cabinet by opening the coin door, removing the front lockdown bar and playfield glass, then raising the playfield and supporting it with the metal prop stick on the inside right wall of the main cabinet. Ensure the playfield is secure in the upright position before continuing.
Locate the ~120-vac wires coming out of the left side of the transformer. These will be 2 brown wires that lead to a 6-pin connector. They will share the connector with 4 black wires which lead to the fluorescent starter, and ballast, mounted on the front of the power supply assembly.
Disconnect the connector as shown.
|
Step 10:
 |
Locate the wiring harness adapter included with the kit and install it between the 2 connectors you disconnected in the previous step.
We recommend slipping the 2nd warning tag over this adapter harness before connecting it (warning tag not shown in image).
Warning tags on the adapter harness and LED lamp will alert future service persons to the changes that have been made to these parts, and help avoid possible problems.
|
| Step 11: | Check your work, then plug game in and turn power on. LED tube should light up right away. If not, turn power off, unplug game, and double-check your work.
