4. Mechanical Instructions
Index of this chapter:
4.1 Service Position
4.2 Cable Dressing
4.3 Assy/Panel Removal
4.4 Set Re-assembly
Notes:
• Only information that is related to the iTV module, is
published in this manual. For the other information, see the
relevant chassis manual (order code on front page).
• Figures below can deviate slightly from the actual situation,
due to the different set executions.
• Follow the disassembling instructions in described order.
Note: To diagnose the set with ComPair it is not needed to
open the set entirely.
To access the ComPair connector, proceed with the following:
1. Manually unlock and remove the cover cap.
2. Remove the tape shielding that covers the ComPair
connector (1).
Note: Make sure that both the ComPair connector and the
UART connector are shielded off with a piece of insulating tape
after repair for ESD reasons. Place this tape over the holes in
the rear cover of the set.

4.1 Service Position
4.1.1 Foam Bars
Figure 4-2 Foam bars
The foam bars (order code 3122 785 90580) can be used for
all types and sizes of Flat TVs. By laying the plasma or LCD TV
flat on the (ESD protective) foam bars, a stable situation is
created to perform measurements and alignments. By placing
a mirror under the TV, you can easily monitor the screen.

4.3 Assy/Panel Removal
4.3.1 Rear Cover
Warning: Disconnect the mains power cord before you remove
the rear cover.
1. Remove the screws that secure the rear cover.
2. Lift the rear cover from the cabinet cautiously. Make sure
that wires and other internal components are not damaged
during cover removal.
4.3.2 i-Board Panel
Figure 4-4 i-Board panel
1. Disconnect all cables from the panel.
2. Untwist the fixation lip [1] c.c.w. with a pair of pliers.
3. Remove the panel.
4.3.3 Side I/O Panel
Figure 4-5 Side I/O panel
1. Disconnect the cable [1] from the panel.
2. Release the two fixation clamps [2] and lift the panel out of
the bracket.
4.4 Set Re-assembly
To re-assemble the whole set, execute all processes in reverse
order.
Notes:
• While re-assembling, make sure that all cables are placed
and connected in their original positions. See Figure "Cable
dressing". Also make sure that the anti-static copper foils
are not damaged and that they make good electrical
contact with the metal frame. Be careful with the fragile
LVDS cable.
