[Adjustment]
Check that the values on page 7/13 of process adjustment are set as below. If not, change them accordingly.
1. Display the current adjustment status at point 6. (Page 8/13 of process adjustment)
The display for checking the adjustment status is toggled by pressing the “6” button on the remote control.
(Normal OSD display 
→ “6” → display for check (OSD disappears) → “6” →normal OSD display → . . . )
2. Read the value of the luminance meter.  x=0.272 , y =0.277
3. Change MGAMMA R6/MGAMMA  B6 (Adjustment offset value) on page 9/13 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 5. (Each time the “5” button on the remote control is pressed, the adjustment status check dis-
play is toggled.)
(Normal OSD display 
→ “5” → Check display (OSD disappears) → “5” →Normal OSD display → . . . )
Change M GAMMA R5/M GAMMA B5 (adjustment offset value) on page 9/13 of process adjustment so that the values of the luminance meter
approach x = 0.272 and y = 0.277.
5. Repeat step 4) for points 4, 3, 2,  and 1.
