< Green LCD adjustment >

1. Confirm connection of the LCD panel (if not con-

nected, connect the LCD to the connector of the PC

board.)

2. Turn the projector on.

3. Input the cross hatch pattern from the RGB connec-

tors. Adjust the green color only.

4. Prepare two focus adjustment jigs. Insert them onto

two holes on bottom of the LCD plate, and adjust the

LCD plate back and forth until the best focus is

obtained in considering left and right balance of the

projection screen. (Refer to Fig.3-2-7.)

5. If the focus or raster geometry is changed, when

tightening the screws holding the LCD mount, loosen

the screws slightly and readjust.

6. Prepare one focus adjustment jig and insert it onto the

upper hole of the LCD plate, and adjust the LCD plate

back and forth until the best focus is obtained in

considering upper and lower balance of the projection

screen. (Refer to Fig.3-2-7.)

7. If the focus or raster geometry is changed, when

tightening the screws holding the LCD mount, loosen

the screws slightly and readjust.

8. When the green LCD is replaced, the pixel matching

adjustments for the red and blue panels will be

necessary in many cases. (If the pixel matching is

obtained in above adjustment, it is not necessary.)

Accordingly, turn off the power. Remove the FPC

section of the red and blue LCDs from the PC board

connectors, and remove the red and blue LCD plate

from the LCD block.

9. Remove the red and blue LCD from the LCD plate

and mount them on new LCD plates.

10. Mount the new red and blue LCD plates on the LCD

block.

11. Perform the adjustment steps (1) – (9) described under

"Red/Blue LCD Adjustment" for each red and blue

LCD.

12. After completion of the red and blue LCD adjust-

ments, perform the steps (10) – (18) described under

"Red/Blue LCD Adjustment".
