Maintenance 26
6.1 Access to Display Interior
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 36). One is centered below the top row
of pixels and one is centered above the bottom
row.
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 the power and ribbon cables (Figure 37).
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.
• 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.
