6.5 Replacing Parts
Location of Internal Components
To replace components inside a display, only the module in front of the specific component
will need to be removed. The components in a typical 12 mm Galaxy displays are located as
shown in Figure 21.
Module Replacement
To remove and replace a module, follow these steps:
1. Locate the latch access fasteners on the module. One is centered below the third row
of pixels and one is centered above the bottom threerows.
2. With a 1 /
8
" hex wrench, turn both latch access fasteners a quarter turn – one latch
turns counter-clockwise to open and the other clockwise to open. Refer to in Figure
25 for a module being removed.
3. Gently pull the module far enough forward to reach behind the back and disconnect
the power and ribbon cables.
4. Connect the power and signal cables to the new module.
5. Position the module in place, making sure that the cables are inside the display.
6. Close both latches using the hex wrench.

Important Notes
• The weather-stripping on the back edge of the module must be intact and in good
condition if it is to prevent water from seeping into the display.
• The module latches must be fully engaged to create a watertight seal around the edge
of the module. The module should be firmly seated against the display when the
latches are fully engaged.
