Drawing A-257029 indicates the location of the TNMC controller for each of the
TNMC models. Figure 13 below illustrates a typical TNMC layout. Complete the
following steps to remove the controller from the display.
1. To access the controller from the front, unlatch the latch fasteners on the
front face the LED module. Refer to
Drawings B-126111 and B-126112 .
(The fasteners are referred to as “latch plugs” on the drawings). One latch
fastener is centered below the top row of pixels and one is centered above
the bottom row. They may be slightly hidden by the louvers.
2. Using a

" nut driver, turn each fastener a quarter-turn. Turn the top latch
clockwise and the bottom latch counterclockwise. Carefully remove the
module and detach the ribbon cables. It may be helpful to label the cables
so you will know which cable goes to which connector when reattaching.
