Service Positions
For easy servicing of this set, there are a few possibilities
created:
•
The buffers from the packaging.
•
The original aluminium stands.
•
Foam bars (created for Service).
4.2.1
Foam Bars
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.
