Important Notes: Disconnect power when servicing the display. Only qualified
service personnel should service internal electronic components.
8.1 About Replacement Parts
The following table contains some of the items that may need to be replaced
in a display over a period of time. These components are generally located
as shown in
Figure 10. If a component is not listed in the replacement parts
list, use the label to order a replacement. Most components within this display carry a label that lists the part
number of the unit. A typical label is shown in
Figure 21 with the part number in bold.
8.2 Instructions for Replacing Parts
Module Replacement
Tool Required:
1
/
8
” Hex Wrench
If LEDs have failed, do not attempt to replace
individual LEDs. Return a failed module to
Daktronics for replacement and/or repair.
Each module can be removed separately without
moving other components of the display.
1. Turn off power to the display.
2. Follow the instructions in Section 6.2
to release the module from the display
cabinet.
3. Disconnect the two ribbon cables from the
module, noting how they are connected
to the back. Release ribbon cables by
spreading the tabs on the sides and then
lifting the cable head from the jack.
4. Unplug the power cables by squeezing
the tabs on the sides of the plug head and
pulling out.
5. Connect all three cables to the new
module, making sure that the ribbon cable
tabs are tightly pushed against the cable
head. Carefully push the ribbon wires
back into the cabinet so they are clear of
the module edges.
6. Place the module into its proper location,
checking that the weather stripping is in
place. Latch the module tightly at both top
and bottom by turning the hex wrench a
quarter turn clockwise.
