(2) Set [R], [G] and [B] Flat Field level to 204, respectively.
(3) Open Menu [Area Shading] and click [STC]. Then adjust
the screen with the slide bar for adjustment level setting
so that the screen is evenly colored.
(4) Open Menu [DDIC] [Flat Field] and set [R], [G] and [B]
Flat Field level to 614, respectively.
(5) Open Menu [Area Shading] and click [DYN]. Then adjust
the screen with the slide bar for adjustment level setting
so that the screen is evenly colored.
(6) Open Menu [DDIC], and set [DYNDAT] [STCDAT] to
[Off].
(7) Open Menu [Flat Field] and set [R] Flat Field level to 204,
[G] and [B] Flat Field level to 0, respectively. Record the
brightness of the screen at this time
(8) Set [R] Flat Field to 614 and record the brightness of the
screen at this time.
(9) Return [DYNDAT] and [STCDAT] to [On].
