1.2" & 2.1" Displays
To remove a power supply that has
failed, first remove the LED module in
front of the failed power supply as
described in LED Module
Replacement.
Each power supply is attached to a
power supply plate by two (2) 3x10
metric screws. The plate is secured to
the back sheet by two (2) #6 screws
and nuts as shown in Figure 33. Use a
5/16” wrench to remove the #6 nuts
(the screws do not need to be removed).
Lift the power supply and plate off the #6 screws. The metric screws securing the power
supply to the plate are now accessible. Use a #1 Philips head screwdriver to remove the
screws and free the power supply.
Both 0.7” and 1.2/2.1” Displays
Disconnect the power cables as shown in Figure 34. The power supply is now fully released
and ready for replacement. Follow the previous steps in reverse order to reattach the new
power supply. Refer to your display’s schematic for the proper wiring configuration.
