[Condition of the unit for inspection]: PC mode, backlight (+16), colour temp (High)
[Input signal condition] : HDMI 1080i 15IRE(LO), 78IRE(HI)
[Adjustment reference device] : Minolta CA-210
[Input signal condition] : HDMI 1080i 15IRE(LO), 78IRE(HI)
[Adjustment]
1) Display the current adjustment status at point HI. (Page 12/14 of process adjustment)
Feed the 78IRE signal.
2) Read the value of the luminance meter. x=0.272, y =0.277
3) Change R GAIN(HI)/ B GAIN(HI) (Adjustment offset value) on page 12/14 of process adjustment so that the values of the luminance meter
approach x=0.272 and y =0.277.
(Basically, G is not changed. If adjustment fails with R and B, change G. When G is lowered, the weaker of R and B must be fixed.)
4) Display the adjustment status of the current point LO.
Feed the 15IRE signal
Change R GAIN(LO)/ B GAIN(LO) (adjustment offset value) on page 12/14 of process adjustment so that the values of the luminance meter
approach x =0.272 and y = 0.277.
approach x =0.272 and y = 0.277.
5) Both HI and LO are repeating the step from 1 to 4 until becoming an aim value.
