(m) Check if the x,y coordinates of color analyzer is in x=0.281 ± 0.015, y=0.311 ± 0.015.
If the color coordinates is out of range, adjust the R.G.B Bias & Gain to get the coordinates in X=0.281,
Y=0.311. Make sure that the coordinates is in range by using contrast control.
(n) Check the screen luminosity up to 30 Ft/L in brightness & contrast control to the maximum. If the screen
luminosity is not satisfactory, readjust the white balance.
