a) Visually check that the display is not tilting left
or right.
b) Manually check that the display can be bent,
lifted, rotated to the left and right normally, and
no abnormal sound indicating that the display
is loose can be heard during this process.
c) Manually check that when the support arm of
the display is pulled, the display can move up
and down with the support arm; when the
support arm wrench is rotated to the
position, the support arm can be locked in the
middle position and then cannot turn left or
right. No obvious loosening is found during the
process.
d) Disassemble the back shell of the control
panel, and use the M5 socket head wrench to
check that the M5X16 hexagon socket cap
screw with plain washer is not loosened.
Visually check that the cable has not been
