4.2 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).
Note: the aluminium service stands can only be used when the
set is equipped with so-called "mushrooms". Otherwise use the
original stand that comes with the set.
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]. 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.

Aluminium Stands
Figure 4-4 Aluminium stands (drawing of MkI)
The new MkII aluminium stands (not on drawing) 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 new stands are backwards compatible
with the earlier models.
Important: For (older) FTV sets without these "mushrooms", it
is obligatory to use the provided screws, otherwise it is possible
to damage the monitor inside!
