Service Positions
For easy servicing of this set, there are a few possibilities
created:
•
The buffers from the packaging.
•
Foam bars (created for Service).
4.2.1
Foam Bars
Required for sets
1
42"
Figure 4-6 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
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.
