< How to mount a new LCD >
1. When mounting a red LCD, mount it on the red LCD
plate (No.23796019) or when mounting a blue LCD,
mount it on the blue LCD plate (No.23796018) so that
the FPC section faces upward and main unit side faces
downward.
2. When mounting a green LCD, mount it on the LCD
plate used so far. In this case, prepare the green LCD
mounting jig (No.23796021), and position the LCD
plate so that its two holes (1) matches two protruded
parts on the jig. Then place the green LCD on it in the
same direction as the red and blue LCDs by tightening
screws (3 holes (2) on the LCD plate).
Note:
• Be always sure to attach the black shielding sheet on
the LCD.

3. Mount the LCD plate with a new LCD mounted at the
bottom side of the LCD block (can be mounted only in
one direction) and tighten the screws. Do not tighten
the screws completely. Tighten the screws temporarily
so that the LCD can move for later pixel matching
adjustment of the LCDs.
Note:
• Do not mount the filter cover to allow the LCD
adjustment.
< Adjustment of LCD >
If the red and blue LCD panels need to be adjusted, follow
the procedures in the item "Red/Blue LCD adjustment".
However, if the green LCD panel needs to be adjusted,
follow the procedures in the item "Green LCD adjustment".
After the green LCD panel adjustment is carried out, it is
necessary to replace or adjust the red and blue LCD panels
as described in the item "Red/Blue LCD adjustment".

< Drive PC board remounting >
Remount the drive PC board under the filter cover not
installed. Connect cables removed from connectors on the
drive PC board and the LCD panel as they were con-
nected. (If a signal generator which can not generate a
white raster signal is not available, do not connect the
LCD panel.)
< Setup >
1. Make a wall chart on white fiber board as illustrated in
Fig. 3-2-6.
