Signal pattern: White raster
Video level: 90%

(3) The color analyzer (CA-210) should be verified by a
spectrum radiation brightness meter such as the CS-1000
or an LCD standard.

Adjustment procedures.
(1) Enter the Service mode menu by following the procedure
in the section 1.1.
(2) Check that the initial data of the adjustment items no. 6,
7 and 8 are in the below shown values. If they are different,
change them to...
No. 6 = 224
No. 7 = 224
No. 8 = 224
(3) Receive the white raster signal. And decrease one or
two of the parameters R DRV_WARM, G DRV_WARM, or B
DRV_WARM in order to meet the X/Y coordinates with the
below values.
NOTE: At least one of the parameters should remain in the
initial value.
REMARKS
(1) Color temperature should be adjusted under the condi-
tion in which the screen is the brightest, thus, the initial value
of adjustment is set at its maximum.
(2) Beware there is RESET in each of picture mode.
(3) When the adjustment items no. 6, 7 or 8 are selected, the
color temperature of the picture changes to warm mode.
(4) Color temperature Warm synchronizes with the drive data
of the Normal mode color temperature. Therefore, when the
drive data of Normal color temperature is changed, the drive
data of the Warm color temperature is changed too.
