4.1 Cable Dressing

4.2 Service Position

4.3 Assy/Panel Removal

4.4 Set Re-assembly
4.1 Cable Dressing
Notes:
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.
F_15800_002.eps

Figure 4-1 Cable dressing

4.2 Service Position
First, put the TV set in its service position. Therefore, place it upside down on a table top (use a protection sheet or foam bars).

4.2.1 The 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 first placing a mirror flat on the table under the TV you can easily see if something is happening on 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.

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.
