Access the table from the front as described in

Remove the malfunctioning module by cutting the red and blue wires connecting
it to the rest of the light string. Refer to
Figure 22 (1)
. Cut the wires as close to the
old module as possible to ensure there is enough leftover wire for reconnection.
Each module is held in place by double-sided tape on the back. Use a flathead
screwdriver underneath the module to pry it free.

Remove any adhesive residue left by the double-sided tape, remove backing from
double-sided tape on new module, and apply it where the old module was just

.
Note:
Instead of using wire nuts to splice the red and blue wires together, a set of
jumper wires (part # 0A-1778-7007) may be connected between the positive
(red) and negative (blue) terminals of the replacement module and another
module above or below it. If there is an additional module in the string after
the replaced module, it must also be reconnected with another set of jumper
wires.
