[Adjustment Procedure]
1) Using the remote control, set the LCD TV to adjustment mode.
2) Measure Max brightness (Lmax).
3) Calculate min. brightness (Lmin)=Lmax/3 000.
4) Measure Point 2 brightness (Lhigh).
5) Set the reference value R,G,B of Point 2 (Ref 2)=2032 x (127/P2)
where P2=255 x [(Lhigh-Lmin)/(Lmax-Lmin)]1/2.2
6) Set the specified gradation for point 2, fix the most faint colour to get reference
value, adjust others 2 colour to minus adjustment for reference value of point 2.
7) Measure Point 1 brightness (Llow).
8) Set the reference value R,G,B of Point 1 (Ref.1)=640 x (40/P1)
where P1=255 x [(Llow-Lmin)/(Lmax-Lmin)]1/2.2
9) Set the specified gradation for point 1. Set G of point 1 to the default value [(Ref.1 x
G value of point 2/Ref.2), with fractions rounded] and adjust RB to the reference
value of point 1.
10)Set the G of point Max. to the default value (4080 x G value of point 2/Ref.2). Set
the R,B Max. value [Gmax-G value of point 2 + (R,B value of point 2)].
11)Adjusted value is writing at [command] MSET0003.
12)Shut down the AC power.
