Adjustment procedures
(1) Enter the Service mode.
(2) Check that the adjustment items no. 0, no. 1 and no. 2
of the Service Mode menu have the next initial values. If the
initial values are different, set them as the following data.
No. 0 = 230
No. 1 = 230
No. 2 = 240
(3) Receive the white raster signal. Step down two (or only
one) of either of the R DRV_COOL, G DRV_COOL or B
DRV_COOL adjustment parameters and change to the
following values
(NOTE: At least one of the adjustment parameters should
remain in the initial data value).
REMARKS
(1) Color temperature should be adjusted under the condi-
tion in which the screen is the brightest, thus, the initial value
of the adjustment is set at its maximum.
This adjustment only decreases brightness.
(2) Beware, there is RESET in each picture mode.
(3) When the adjustment items no. 6, 7 or 8 are selected, the
color temperature of the picture changes to warm mode.
4.2 Normal Mode.
