Service. Take note of the following part number formats. (Not all possible formats
are listed here.)
• “0P- _ _ _ _- _ _ _ _” denotes an individual circuit board, such as a driver
board.
• “0A-_ _ _ _ - _ _ _ _” denotes an assembly, such as a circuit board and the
plate or bracket to which it is mounted. A collection of circuit boards
working as a single unit may also carry an assembly label.
• “W- _ _ _ _ ” denotes a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true for
ribbon cables.
Most circuit boards and components within this display carry a label that lists the
part number of the unit. If a circuit board or assembly is not listed in the
Replacement Parts List in Section 4.5, use the label to order a replacement. A
typical label is shown in
Figure 4. The part number is in bold.
