Before conducting Unit replacement work, always be sure that every
cable-tie that fastens the cable has been removed.
Replacement work without the above may lead Unit/cable breakage.
Step 3 Remove the top and bottom screw covers of the monitor.
Using a 4 mm width flat head screwdriver, remove the top and bottom screw covers of the
monitor.
The top and bottom screw covers are fastened with six stoppers and seven stoppers,
respectively. Insert a flat head screwdriver into the driver insertion slots at both edges and remove
each cover by raising the cover from the edges little by little. If you try to remove the covers by
force, it may damage the monitor or break the screw covers, so be careful.
Do not damage the screw covers while removing them. Hold down each screw cover near the
stoppers, slowly apply force in the vertical direction to eliminate flexure as much as possible,
and then remove the cover
