Daktronics signs are built for long life and require little maintenance. However, from time to time,
certain sign components will need replacing. The Replacement Parts List in Section 4.11 provides the
names and part number of components that may need to be ordered during the life of the sign.
Following the Replacement Parts List is the Exchange/Replacement Procedure in Section 4.12.
Refer to these instructions if any sign component needs replacement or repair.
1.2 Safety Precautions
1. Read and understand these instructions before installing.
2. Be sure that the display is properly grounded.
3. Disconnect power before working on the display.
4. Do not modify the display structure or attach any panels or coverings to the display
without the written consent of Daktronics, Inc.
5. Care must be taken when handling the display’s face panel to prevent any injuries or
damage, especially in windy conditions.
1.3 Daktronics Nomenclature
To fully understand some Daktronics drawings, such as
schematics, it is necessary to know how various
components are labeled in those drawings. This
information is also useful when trying to communicate
maintenance or troubleshooting efforts.
Introduction 1-2
A module is the building block of the Galaxy sign. Each
module measures 16 pixels high by 48 pixels wide. By
placing modules side-by-side and on top of one another a sign
of any size can be designed and built. Individual modules can
be easily removed from the sign if required. Figure 2
illustrates how Daktronics numbers modules on a Galaxy
sign. Figure 3 breaks down the module numbering method.
