Daktronics displays are built for long life and require little maintenance. However,
from time to time, certain display components will need replacing. The
Replacement Parts List in Section 4.11 provides the names and numbers of
components that may need to be ordered during the life of the display. Most display
components have a white label that lists the part number. The component part
number is in the following format: 0P-_ _ _ _-_ _ _ _ (component) or
0A-_ _ _ _-_ _ _ _ multi-component assembly).
Following the
Replacement Parts List is the Daktronics Exchange and Repair

component needs replacement or repair.
