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.

Instructions below apply to the 42HFL5682L/xx, but will be

completely disconnected from the back-end board. Both
boards could be damaged. Do not damage the EMC foam
