Replacing the LCD
Display
The Model GC868’s measurements are displayed on a a two-pane
LCD graphic display panel. The LCD display normally provides
years of dependable service, but it is easily field-replaceable when
necessary. To replace the LCD display, see Figure 4-1 on page 4-10
for the component locations, and complete the following steps:
1. Remove the printed circuit board, as described in a previous
section of this chapter.
2. Using a 3/16” nutdriver, remove the four nut/washer sets that
secure the display shroud to the inside of the console cover. Lift
the display shroud off its mounting studs.
3. Using a 1/4” nutdriver, remove the four standoffs that secure the
LCD display assembly to the console cover. Lift the LCD display
assembly off its mounting studs.
4. Place the new LCD display assembly over the mounting studs on
the console cover and fasten it in place with the four standoffs.
Make sure that the LCD display assembly is oriented as shown in
Figure 4-2 on page 4-11.
Caution!
Do not overtighten the standoffs or the display assembly
may be damaged.
5. Position the LCD display cables between the two right side
mounting studs, and install the display shroud over the mounting
studs. The top and bottom edges of the shroud are bent at a 90 °
angle to the main surface, and these edges must face inwards
toward the display assembly.
Note:
One edge of the display shroud is covered with a piece of
black electrical tape. This side of the shroud should be on the
right, to protect the cables against abrasion.
6. Fasten the display shroud to the console cover with the four sets of
nuts/washers.
Caution!
Do not overtighten the nuts or damage to the mounting
threads may occur.
Complete the LCD Display replacement by proceeding to the
Installing the Printed Circuit Board section on page 4-7.
