Powering Off the System
Power off the system by turning the power switches to the Off position on the two left PDUs, single right
PDU and, if present, the PDU or auxiliary control unit behind the center display assembly.
Caution Make sure all system power is turned off before beginning this disassembly.
Removing Audio Components
Caution Take care not to mar or introduce smudges or dirt to the surface of the projector screen.
Step 14 Remove the Projector screen by performing one of the following actions:
• If your projector screen is slightly recessed and uses black side trims, complete the following steps:
a. Remove the side trims from the edges of the display.
Be careful not to mar the screen when you perform this step.
b. Use an open-ended wrench to loosen the feet on the bottom of the screen, and lower the screen.
c. After you have created a gap of approximately 1/2 inch (1 centimeter) between the screen and
the display shelf, detach the holes on the top screen from the locating pins on the underside of
the display shelves and remove the screen.
• If your projector screen does not have side trims and is flush with the display cabinet, grasp the outer
edges of the screen and pull it up and away from the Projector clips that hold the screen to the
Display shelves.
Step 15 Disconnect the Speaker cables from the Speaker terminals.
Step 16 Loosen the half-turn bolts on either side of the left Speaker board. Slip the Speaker board over the
half-turn bolts and remove it from the work area.
Step 17 If you are replacing the center or right Plasma display, remove the center speaker board by repeating
Step 15 and Step 16.
Step 18 If you are replacing the center Plasma display, proceed to the next section, “Removing the Camera
Cluster”.
Step 19 If you are replacing the right Plasma display, remove the right speaker board by repeating Step 15 and
Step 16.
Step 20 If you are replacing the right Plasma display, skip to the “Removing the Left Tabletop Door Section”
section on page 11-8.
