System Disconnected

If the Touch-screen Display is not blank, but is displaying “System Disconnected!” in the middle of the screen,
ensure the 4 by 1 Molex connector, located behind the display at the top, is connected and that the wires are fully
inserted (see Figures 16-2 and 16-3). If the connector appears to be fine, check the wiring connections on the
back of the touch-screen display (remove display assembly, see Figure 16-3); Green, Red and Black go to
terminals 1, 2 and 3 respectfully.
