Service Positions
For easy servicing of this set, there are a few possibilities
created:
•
The buffers from the packaging.
•
Foam bars (created for service).
•
Aluminium service stands (created for Service).
4.2.1
Foam Bars
Required for sets
1
42"
Figure 4-3 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].
Caution: Ensure that the foam bars are always supporting the
cabinet and never only 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.

Aluminium Stands
Figure 4-4 Aluminium stands
The MkII aluminium stands with order code 3122 785 90690,
can also be used to do measurements, alignments, and
duration tests. The stands can be (dis)mounted quick and easy
by means of sliding them in/out the "mushrooms". The stands
are backwards compatible with the earlier models.
