Adjusting flapping of the green lens
After finishing the lens focus adjustment, adjust flapping of the green lens
(angle of the green CRT) so that the upper and lower parts, and the left and
right parts of the screen are equally in focus.
1
Open the upper cover.
For how to open the upper cover, see page 17 (EN).
2
Remove the front cover and the CRT fixing screws.
For how to remove the front cover, see page 18 (EN).
Each CRT is locked with two CRT fixing screws at the factory. When
you adjust flapping for the first time, be sure to remove all six CRT
fixing screws.
3
Place a white paper over the front of the screen. Note whether the focal
surfaces on the upper, lower, left and right parts of the screen appear to
be leaning forward or backward.
