1. 
Using R/C, set the LCD TV to adjustment mode.
2. 
Set the specified level for point 7, and measure the luminance.
Set the R/G/B initial value tentatively, then treat the strongest color of R/G/B 
as fixed value, adjust remained other.
2 colors by reducing value to get “target value” of point 7.
  R>G  Ye=G*1.05
When the value of Ye over an initial value ( 928 ),set value 928.
  R≦G  Ye=R*1.05
When the value of Ye over an initial value ( 928 ),set value 928.
Set the value of Ye which was calculated from the above conditional expression
in MG7YXXXX.
Adjust R/G/B repeatedly until converging to “target value”.

[Caution]
 To measure the chromaticity and luminance , please wait more
 than the following delay time from return marks of “OK”.
 Because there is a delay time to output the pattern after
 executing a test pattern output command.
  
* Picture delay time : 70ms
  (the maximum total delay of the main microcomputer
 and LCD controller)
[ Target value for adjustment ]
 The target value applies correspondingly to the teaching set.
 And read the target value from the marking position.
