TNMC & Electronic Caption Troubleshooting & Maintenance 41
For Displays Built Before September 2009
Figure 33 illustrates the component locations of an older 8x48-34mm display, and this layout
will also be similar for 8x32-34mm and 8x64-34mm cabinets. Refer to Drawing A-257029.
Figure 34 illustrates the component locations of an older 8x48-46mm display. The 8x32-46mm
cabinets only include a single power supply assembly.
Standard Daktronics outdoor LED scoreboards are typically front-accessible, but some
models may be ordered with rear service access. For that reason, TNMCs and electronic
captions have been designed so that they may be accessed from both the front and rear.
Front Access
1. Loosen the latch fasteners on the front
face the LED module using a 1/8" hex
wrench (or
7
/
32
" nut driver for displays
installed prior to 11/29/05). One latch
fastener is centered below the top row of
pixels and one is centered above the
bottom row (Figure 35).
2. Turn each fastener a quarter-turn
counter-clockwise (if using a nut driver,
turn the top latch clockwise and the
bottom latch counterclockwise).
Note: Do not over turn the fastener!
3. Carefully remove the module from the face of the display.
