Replacing the LED Board

•
The LED Board can be damaged by static electricity.
Before handling the LED Boards, always touch an earthed metal surface to
discharge any static electricity.
•
If the two LEDs (red spots) under the Monitor Mask's filter (see illustration below) do
not illuminate, the LED board may be defective or malfunctioning.
As any defective LED Board will prevent the proper functioning of the game, replace
the defective LED Board as soon as possible.

2. Disconnect the LED Board's two connectors, remove 2off whizz nuts (M3), and remove
the defective LED Board.
