Instructions for mounting the SSB
To mount the (replacement) SSB, perform all the steps of the
SSB removing procedure in reverse order.
Caution
Avoid the risk of damage to the SSB or failing circuitry!
The TV set might reboot under load conditions (regardless of
the firmware version), when thermal foams are not present or
not fully covering the SOC and other circuits!
Observe the following rules when handling the SSB:
• Make sure that all parts are at the right location.
• Carefully check all thermal foams between the SSB and
the display panel.
Refer to the drawings with thermal foam locations for SSB
in Chapter 10. Circuit Diagrams and PWB Layouts
sure that:
– all required foams are present on the display panel,
– no foam is damaged,
– each foam has the right dimensions,
– each foam is placed at the right location (with the right
angle),
• Make sure not to damage the EMC foams on the SSB
shields and that they are correctly mounted.
• Insert all screws at the original position.
• Make sure that all cables are placed and connected in their
original position. See Wiring Diagrams in Chapter
