Daktronics displays are built for long life and require little maintenance. However, from time
to time, certain display components will have to be replaced. The Replacement Parts List in

component.
1.2 Daktronics Nomenclature
To fully understand Daktronics drawings, it is necessary to know how various components
are labeled in drawings. This information is useful when trying to communicate maintenance
or troubleshooting efforts. The label “A” on a drawing item typically denotes an assembly.
An assembly can be a single circuit board or a collection of components that function
together, usually mounted on a single plate or in a single enclosure.
In addition, the following labeling formats might be found on various Daktronics drawings:
ƒ
“TB _ _” denotes a termination block for power or signal cable.
ƒ
“F _ _” denotes a fuse.
ƒ
“E _ _” denotes a grounding point.
ƒ
“J _ _” denotes a power or signal jack.
