6. Turn off both breakers inside the sign by clicking the blue buttons on the breakers until they click
   out.
7. Inside the Entrance Sign on the 2-pole breaker for the air conditioner, flip the switch down to
   power off.
8. Shut off the electricity to the Entrance Sign by turning the sign’s breaker off inside the ICS
   power distribution box.
9. Shut off the electricity to the air conditioner/heat exchanger for the Entrance Sign at the site’s
   main electrical service panel.

Completion Time

We estimate that it will take 1 hour to perform this procedure. Keep all hardware organized as you work. Please read the entire procedure before starting.

Procedure

1. Identify the location of the motherboard, video controller, and power supply inside the back of the digital Entrance Sign.
   
   
   
   
2. Identify the location of the cables that need to be disconnected.
   
   
   
   
3. The DVI cable is connected to the video control board and motherboard with 2 screws in each connector. Loosen these screws until the connector comes off each board. See Figure 3 for the video control board.
4. Use a small flat screwdriver to remove the orange and black board power wires from the video control board. Remove the backlight control wires by pulling on the connector until it is free from the video control board.
   
   
   
   
5. Using your fingernail, flip upward on the clips holding the ribbon cables on the left side of the video control board panel to the back of the display panel.
   
   
   
   
6. Remove all the 24VDC+ and 24VDC- connections from the power supply. Remove the 12VDC+ and 12VDC- connections for the motherboard.
   
   
   
   
7. Locate the 12V wires just removed from the power supply. Disconnect the other end of that cable from the motherboard. It will not be needed.
8. Hold the video board control panel (including metal plate) with one hand while removing the (2) screws on the left holding it to the back of the display panel. After you remove the screws, slide the video control board panel to the right and lift out of the Sign.
   
   
   
   
   
   
9. Locate the replacement Video Control Board Panel.
10. While holding the video control board panel in place with one hand, attach the ribbon cables to the connectors, and then close the clips. Continue to hold the video board control panel while you attach (2) screws that hold the video control board panel to the back of the display panel.
    NOTE: The Ribbon Cables are very delicate, please be careful.
    
    
    
    
11. Identify the location of all the cables to be connected.
    
    
    
    
12. Remove the 24 VDC power cable to the backlight. Discard this cable. A new cable will replace the one you are removing in the next few steps.
    
    
    
    

Installing Video Control Board

1. Install the new 24VDC power cable to the backlight.
   NOTE: The difference in the number of wires going to the upper and lower connector sockets on the display. The lower connector has more wires in it. Also, the pigtail for the backlight control wire splits off the cable near the lower connector.
   
   
   
   
2. Locate the new 12V power cable.
   
   
   
   
3. Attach the white connector to the power terminal on the motherboard. It can only be inserted one way.
4. Connect the control board power wires to the circuit board. Be sure the screws in the plug are visible on top before plugging it in. 
5. Connect the backlight control plug to the backlight connector on the left side of the board.
   
   
   
   
6. Connect the 12V cable to the power supply. Please observe the diagram on the power supply for the proper location for these connections. (12VDC- is wired to 12V COM on the power supply, not 12VDC-.)
   
   
   
   
7. Locate the new HDMI cable shown in Illustration 2. Attach the HDMI cable to both the video panel and the motherboard. Either end of the cable can go in either location. See Figure 19 and Figure 20.
8. Completed Assembly.
