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 Spare Part list (SBOM) and 10-7-3 Thermal
Foams on 8700 series to make 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 (and with the
right angle),
•
Make sure the EMC foams on the SSB shields are not
damaged and correctly mounted.
•
Insert all screws at the original position.
•
Make sure that all cables are placed and connected in their
original position.
