6.1 Internal Display Access
Daktronics GalaxyPro ® displays provide access to internal components by removing the front
modules. The display may need to be opened to perform maintenance or for troubleshooting.
To access the interior of the display, perform the following steps:
1. Disconnect power to the display.
2. Locate the latch access fasteners on the module
(Figure 37). One is centered below the second
row of pixels and one is centered above the
bottom two rows.

3.
With a 1 /
8
" hex wrench, turn the latch access
fasteners a quarter turn counter-clockwise.
Gently pull the module far enough forward to
reach behind the back and disconnect the power
and ribbon cables (Figure 38). Note the cable
connections so they can later be reconnected
correctly.
4. Disconnect the two ribbon cables from the
module by spreading the tabs on the sides and
then lifting the cable head from the jack. Note
how they are connected to the back.
5. Unplug the power cable by squeezing the tabs on
the sides of the plug head and pulling out.
6.
When ready to reinstall the module, reconnect
the cables to the module, making sure that the
tabs are tightly pushed against the cable head.
Carefully push the ribbon wires back into the
cabinet so they are clear of the module edges.
7.
Place the module into its proper location, checking that the weather stripping is in
place. Latch the module both top and bottom by turning the hex wrench clockwise a
quarter turn.
Note:
• 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.
Figure 38: Removing a Module
• 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.
