Mechanical Instructions
1. Remove the middle fixation screw (1) from the bottom side
of the connector plate (as this holds the SSB bracket).
Note: Sometimes it is easier to loosen the complete
connector plate and remove it together with the SSB.
2. Remove all connector fixation screws (2) from the front
side of the connector plate.
3. Remove the two female screw locks (3) of the VGA
connector.
4. Release the plastic cable clips (4) on the shielding and
disconnect all cables from the SSB.
Note: Be careful with the fragile LVDS connector on the
SSB.
5. Now, completely remove the SSB (together with all the
shieldings) from the set.
6. Once the SSB is out, remove the fixation screws (5) from
the shielding.
7. Remove the shielding, it hinges at the left side (acc. photo).
8. Remove the fixation screws that hold the panel(s), and take
out the panel(s).
Notes:
•
Pay special attention to the EMC foam on the SSB
shielding. These must be replaced in their initial positions
during set re-assembly.
•
Insulate the tuner pins, so they cannot touch the shielding
(see also figure "SDM Service jumper" in Chapter 5).

Disassembly
1. Place the TV set face down on the foam bars. Place the
bars at the edges of the set, so they will support the front
frame and not only the glass plate!
2. Remove the LED/Switch and Top Control panels (1).
3. Next step is to unplug the following cables (see also
"Wiring Diagram" in Chapter 6):
–
AC Power (Mains) plug between Mains Filter and PSU
(loosen cable from clamps).
–
All cables on the Audio panel.
–
LVDS plug on SSB. Caution: Be careful, because this
connection is very fragile!
–
SSB supply plugs on PSU.
–
Audio Panel supply plug on PSU.
