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.
