Repeat steps 4 through 10 for the blue
CRT, except now you will cover the

can cut off the unnecessary colors in the
service mode by individually changing
the data in adjustment category "2150P-
2" , item # 1"RGBS". To display blue
only, change the data to "1", to display
green only, change the data to "2", to
display red only, change the data to "4".
All colors are displayed when the data is
set to "7".
