Maintenance 21
Section 6: Maintenance
Power must be turned OFF before any repair or maintenance work is done on the display.
Qualified service personnel are recommended for servicing internal electronic components.
Daktronics’ engineering staff must approve ANY changes made to the display. Before altering the
display, detailed drawings for proposed modifications must be submitted to Daktronics’ engineering
staff for evaluation and approval, or the warranty will be null and void.
Daktronics GalaxyPro Revolution displays are both front and rear accessible, meaning internal
components are accessed by removing either the modules or rear access panels. The display must be
opened to perform maintenance or troubleshooting. Figure 21 shows internal component locations.
Some components are restricted to specific sections. For example, Multi-Line Controllers (MLCs) are
only located in the left sections while the controller is only located in the lower left section. Refer to
the appropriate Layout Drawings for the location of components in specific display sizes.
