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 part number 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-_ _ _ _-_ _ _ _ (circuit board) or 0A-_ _ _ _-_
_ _ _ multi-component assembly).
Following the Replacement Parts List is the Daktronics Exchange and Repair and
Return Programs in Section 4.12 . Refer to these instructions if any display
component needs replacement or repair.

The concept of using LED displays as a cost effective, high impact method of
communication is rapidly growing throughout many industries and businesses. The
reasons for this growth are many, but the need for additional features and complexity
of multiple display installations has emerged. Daktronics display systems have been
designed to meet those needs.
