Maintenance
Caution:
• Never pull on the flex cable. This may damage the cable end or the connector.
• Take care when handling cables and connectors. They are fragile and can be damaged.
Note:
• Due to the short length of the video cable, remove it prior to fully opening the case.
• Proper operation of the monitor depends upon correct cable re-insertion following disassembly. Ensure
that the flex cable is aligned properly and fully inserted into the connector prior to locking the connector
tab down.
3 Remove the touchscreen five-wire cable from the CPU PCBA.
4 Remove the power switch/monitor assembly by sliding the “ZIF” connector locking mechanism outward,
then removing the cable from the socket.
5 Unlatch the touchscreen cable and remove the eight 6-32-inch × 1/4-inch screws (three along the top, three
in the center, and two at the bottom of the PCBA).
If you are replacing the front bezel, proceed to the next section (Replacing the Display or Touchscreen
Assembly, Backlight Inverter, and Power Monitor Assemblies) for removal of the remaining front bezel
assembly components.
