Monitor Replacement
Perform the steps that follow to remove the monitor from the cabinet for service or replacement.
Be sure to follow all safety precautions while working with a monitor.
Tip:
When removing the monitor from the cabinet, it is always best to have two people to
support the weight of the monitor.
1.
Turn the cabinet OFF and disconnect the AC power cord.
2.
Disconnect all cables that connect the monitor to the cabinet, typically the following:
•
VGA Video cable from the back of the Monitor.
•
Power cable that connects to the monitor chassis PCB, located on your left as you
face the monitor rear.
•
Green
ground wire from the monitor frame on some models.
3.
Remove the monitor remote control board from inside the coin door. Coil this cable and tie it to
the monitor to prevent it catching while the monitor is being removed.
4.
Inspect the disconnected cables and monitor frame to make sure that there are no wire ties
holding the monitor to the cabinet.
5.
Remove the retaining brackets from above and below the monitor. The upper bracket is secured
with three Torx security screws, the lower bracket with four screws (two near each end).
