< 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".

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.
