The Replacement Parts List in Section 8.9 includes part numbers of components it may be
necessary to reorder during the life of your display. Most scoreboard components have a white label
that lists the part number. Refer to the Replacement Part List and the drawings in this manual to
obtain the correct replacement part number for any damaged component. Also refer to the
appropriate manual for a list of potential problems with add-on or separately-mounted message
centers.
For troubleshooting assistance and to order replacement components, contact your service provider
first. Your service provider may have the appropriate part or assembly on hand and, in an
emergency, may be able to provide same-day service.
Your scoreboard service may advise you to call Daktronics directly, or your facility may not have an
area or regional service provider. In those instances, feel free to call the Daktronics Help Desk at
877-605-1115. For faster service, note the model of the scoreboard and any problem-area assembly
numbers, as shown on the scoreboard spec sheet. If you need to order replacement components, it
would be helpful to have a purchase order number or other purchase information available at the
time you call.
