Replacing the PanelMate® ePro PS, PanelMate ePro PS EE, and
PanelMate ePro PS OD 7685x-12 Series Backlight Assembly
Introduction
The Backlight Replacement Kit provides a replacement backlight for the PanelMate ePro PS 7685T-12
Series, the PanelMate ePro PS EE (Enterprise Edition) 7685T-12E Series, and the PanelMate ePro PS
OD (Outdoor) 7685T-12OD Series. Although the figures provided are for the ePro OD models, the
disassembly for the ePro PS and ePro EE models are the same.

Backlight
Disposable Anti-static Wrist Strap
Caution: Electrostatic Discharge (ESD) can damage static-sensitive electronic components. You
should perform these procedures only at an ESD workstation. If an ESD workstation is not
available, you can provide some protection by wearing an anti-static wrist strap and
attaching it to a metal part of the system chassis.
Warning: This procedure requires electrical and mechanical skill and should be attempted
only by qualified technicians.
Required Tools
Phillips screwdriver size P0 and P1. Magnetic would be helpful.
Nut Driver or socket size ¼”
Jewelers small phillips screwdriver. Magnetic would be helpful.
Small electronic cutters
Instructions for Replacing the Backlight
1. Disconnect the power source cable and any other cables from the PanelMate unit.
2. Remove the chassis cover from the electronics module by unscrewing the five screws at the back of
the unit and the single screw on the connector side of the unit. See Figure 1.

16. Gently and carefully, pull the backlight cartridge out of the display. Make sure to pull the backlight
cartridge straight out.
Caution: The backlight cartridge is very fragile. Any twisting or bending during removal can cause
the lamps to break possibly leaving broken glass inside the display.
17. Gently and carefully, insert the new backlight cartridge into the display. Slide the backlight cartridge
very carefully and straightly. Make sure not to twist or bend the cartridge. Be careful not to push or
tug on the wires attached to the backlight cartridge as they are very fragile. See Figure 10.
Caution: The new backlight cartridge is very fragile. Any twisting or bending during insertion can

Figure 9 and Figure 7.
20. Reattach the display to the display plate. See Figure 8.
21. Reattach the backlight cables to the inverter board. Ensure the two wires in each connector are on
either side of the small white standoffs. See Figure 7.
22. Reattach the inverter board. See Figure 7.
23. Reattach the display plate to the front panel making sure to feed the touchscreen cable through the
opening in the plate. See Figure 7.
Cleaning: Clean off any fingerprints or dirt that may have gotten on the inner display surface or the
backside of the front panel.
24. Place the video cable back under the two cord clips. See Figure 7.
25. Tilt the board along the fan edge to reconnect the video cable and the inverter cable. See Figure 6.
