Instructions for Replacing the Backlight in a
1785 Series Unit
1. Disconnect the power source cable and any other cables from
the PanelMate unit. If a high-speed interface module is attached,
remove the module.
2. Remove the cover from the electronics module by unscrewing
the screws holding the cover on.
3. Remove the circuit board by removing the standoffs, and the
screws holding the circuit board to the display plate assembly.
4. Disconnect the backlight cable from the inverter. If necessary,
you may have to remove the inverter by removing the screws
connecting the inverter to the display plate.
Note:
In newer models, a standoff has been placed next to the back-
light cable connector to prevent it from disconnecting from the
inverter. The inverter has to be removed in order to disconnect the
backlight cable.
5. Remove the standoffs on the display plate to release it from the
front panel.
6. Remove the display module from the display plate by unscrew-

cartridge by unscrewing the two screws holding the backlight
cartridge to the display module and sliding gently apart about 1/8
inch and then lifting up.
