Mechanical Instructions
Index of this chapter:
1. Set Disassembly
2. Service Position
3. Assies/Panels Removal
4. Set Re-assembly
1. Disconnect the degaussing coil [1].
2. Release the two fixation clamps (at the mid left and mid
right side of the bracket), and remove the bracket from the
bottom tray, by pulling it backwards [2].
3. Turn the chassis tray 90 degrees counter clockwise.
4. Move the panel bracket somewhat to the left and flip it 90
degrees [3], with the components towards the CRT.
5. Turn the panel bracket with the rear I/O toward the CRT.
6. Place the hook of the tray in the fixation hole of the cabinet
bottom [4] and secure it.
Note: Figures below can deviate slightly from the actual
situation, due to different set executions.
4.1 Set Disassembly
Warning: Be sure to disconnect the AC power from the set
before opening it.
4.3 Assies/Panels Removal
4.3.1 Front Interface Assy/Panel Removal
4.1.1 Rear Cover
1. Remove all fixation screws of the rear cover (do not forget
the screws that hold the rear connection panel).
2. Pull the rear cover backwards to remove it.
4.2 Service Position
1
Before placing the Mono Carrier in its service position, remove
the Front Interface assy/panel (see paragraph “Front Interface
Assy/Panel removal”), the Side AV assy/panel (see paragraph
“Side AV Assy/Panel removal”) and the PIP assy/panel (if
exists) (see paragraph “PIP Assy/Panel removal”).

1. Remove the complete module from the bottom plate, by
pulling the two fixation clamps upward [1], while sliding the
module away from the CRT [2].
Note : these clamps are difficult to access.
2. Release the two fixation clamps [3] at the side of the
bracket, and lift the panel out of the bracket (it hinges at
one side).
