Section 10: Display Maintenance
This section explains the steps necessary
to maintain the GalaxyPro ® GP3 display.
Daktronics GalaxyPro ® GP3 displays
are front accessible. Remove modules
on the front of the display to gain access
to internal components. Figure 19 and
Figure 22 show internal component
locations.
Important Notes: Turn OFF power before
any repair or maintenance work is done
on the display.
10.1 Internal Display
Access
1. Disconnect power to the
display.
2. Locate the two access holes to
gain access to the quarter-turn fasteners
on the module.
3. Using a 1 /
8
” hex head wrench, turn each latch a
quarter turn
counter-
clockwise.
4. Gently pull
the module
far enough
forward
to reach
behind and
disconnect
the power
and signal
cables.
Note: Do not
allow module
