• Re-assembly
Note: Figures below can deviate from the actual situation, due
to different set executions.
4.1 Service Position Monitor
Figure 4-1 Service Position
First, put the monitor in its service position. (Can be done via
buffers as showed on figure, but preferable via new service
position solution as described below. Still some improvising is
needed for service positions panels however). Therefore,
disconnect all cables connected to the monitor and take the
monitor of the wall (or tabletop stand). Then, fix the monitor to
the 2 service-poles. (the 2 poles together form a service-kit:
3122 785 90480; this service-stand can be used for 30” until
42” FTVs.
4.2 Rear Cover Removal
To be able to access or measure the panels, remove the rear
cover (metal back plate):
Warning: make sure that the mains power is disconnected
before you remove the metal back plate.
1.
Remove all fixation screws of the back plate, as indicated
in the figure above (five at the top, five at each side, seven
at the bottom and the two larger ones just below the 'wall
mounting holes').
2. Remove the metal back plate. Make sure that wires and flat
foils are not damaged during plate removal.
4.3 Service Position Panels
4.3.1 SCAVIO Panel
Solder-side SCAVIO
Figure 4-2 Service position SCAVIO (1)
To access the panel:
1.
Remove the cables from connectors 0320, 0305, 0301,
0319 and 0388 on the SCAVIO panel.
2. Remove the power cable from the mains power inlet to the
power supply (connector 0308).
3. Remove the five screws at the bottom of the SCAVIO-
panel cover plate.
4. Hold the SCAVIO panel while removing the top screw, in
order to prevent that it will fall.
5. Take the panel out, and turn it 180 degrees, so that you
face the solder side of the SCAVIO panel.
6. Reconnect all cables. Use a standard power cable to
connect the mains directly to PSU-connector 0308, and
use the 'LED/Switch panel' service kit 3122 785 90410 (as
the original cable is too short).
Caution: When measuring, watch out for the 'hot' left heat sink
of the PSU!
Another way to measure the SCAVIO panel:
1.
Remove the five screws at the bottom of the SCAVIO-
panel cover plate.
2. Hold the SCAVIO panel while removing the top screw, in
order to prevent that it will fall.
3. Put a piece of paper (or cardboard) in front of the Power
Supply.
4. Take the panel out, and turn it upward [B], so that you face
the solder-side of the SCAVIO panel.
Caution: Make sure that the metal connector plate does not
touch any 'hot' part of the Power Supply (heatsink).
