4.2.1 Foam Bars
Required for sets
1
42"
Figure 4-2 Foam bars
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. See figure "Foam
bars" for details. Sets with a display of 42" and larger, require
four foam bars [1]. Ensure that the foam bars are always
supporting the cabinet and never only the display.
Caution: Failure to follow these guidelines can seriously
damage the display!
By laying the TV face down 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 monitor
the screen.

4.3.2 Keyboard Control Panel
1. Refer to next figure.
2. Remove the T10 parker screws.
3. Unplug connector.
4. Remove the unit. Note: as the unit is "secured" by bosses
located on the front cabinet, it can be difficult to remove the
unit. Therefore, it is advised to use a long thin screwdriver,
insert it vertically between the control knobs and the front
cabinet, and use it as a lever (see arrows) while pulling the
unit from the cabinet. You will here some "clicks" during
removal.
5. Release clips and remove the board.
When defective, replace the whole unit.
