4.2 Service Positions

For easy servicing of a TV set, the set should be put face down
on a soft flat surface, foam buffers or other specific workshop
tools. Ensure that a stable situation is created to perform
measurements and alignments. When using foam bars take
care that these always support the cabinet and never only the
display. Caution: Failure to follow these guidelines can
seriously damage the display!
Ensure that ESD safe measures are taken.

4.3.1 Rear Cover

Warning: Disconnect the mains power cord before removing
the rear cover.
1. Remove the fixation screws that secure the rear cover.
2. Lift the rear cover from the TV. Make sure that wires and
flat foils are not damaged while lifting the rear cover from
the set.

4.3.2 Small Signal Board (SSB)

Caution: it is mandatory to remount all different screws at their
original position during re-assembly. Failure to do so may result
in damaging the SSB.
1. Release the clips from both the LVDS Flat Foil connectors.
Caution: be careful, as these are very fragile connectors!
Take the flat foils out of their connectors.
2. Unplug all other connectors.
3. Release the tape near the bottom side of the set from the
LCD panel.
4. Remove all other fixation screws from the SSB.
5. Take out the SSB together with its shielding.
6. Remove the screws near the HDMI and L/R audio

Caution: be careful not to damage the thermal pad
between the SSB and shielding.

4.3.3 Power Supply Unit (PSU)

Caution: it is mandatory to remount all different screws at their
original position during re-assembly. Failure to do so may result
in damaging the PSU.
1. Unplug power connector from the SSB and remove the
wire wrap from this cable.
2. Unplug all other connectors from the PSU.
3. Remove all fixation screws from the PSU.
4. The PSU can now be taken out of the set.
