Install the Replacement LCD:

Once the original LCD is completely removed, the replacement can be

installed in its place.

Since there is a slight difference in the depth of the LCD dimensions, the

LCD must be mounted differently than the original. Also, the top 4 pins on

the LCD must be covered in order to prevent them from shorting on the

metal mounting frame. Figure 13 indicates the pins which must be covered

and Figure 14 shows those pins covered with electrical tape.

In order to account for the difference in depth the replacement LCD must

be placed behind the mounting frame as shown in Figure 15. The top 2

screws must be screwed in from the backside as shown in Figure 16, 17

and 18. The bottom right screw can be screwed in from the front as shown

in Figure 17.

Once the replacement LCD is mounted in place, plug the cables in, as

shown in Figures 18, 19, and 20.

Fig. 21 - Testing the LCD

Test the LCD:

Now that the replacement LCD is mounted and plugged in, it is possible to

test the LCD to make sure it is properly installed and working before closing

the unit up.

Since the case is opened be sure to be cautious and avoid touching the

insides of the unit when it is powered up, this may result in a shock or

worse.

To test the LCD, plug the unit up and power it on, the LCD should light up

and display characters. The LCD contrast can be adjusted as needed by

turning the contrast knob.

Once the LCD is verified working, the installation is complete. Power off the

unit and unplug it, then screw it all back together. Install completed.
