3 – 7

Adjustment gradation values (INFO) appear on page 7/7 3-4 lines of process adjustment, and adjustment initial values (offset value) appear on pages
7/7 5-10 lines. For white balance adjustment, adjust the offset values on pages 7/7 5-10 lines.

1. Preparation

1) Luminance meter reference device                          :Minolta CA-210

2) Condition of the unit for adjustment and inspection  :Modulated light: MAX (+16)

2. Setting

1) The luminance meter is set to the center of the screen of the set. 

2) In “INCH SIZE” on the process adjustment page 1/7, sets it to the size of each panel with the  /  key to R/C. 

3. Adjustment method

Check that the values of point A and B on page 7/7 of process adjustment are set as below. If not, change them accordingly.

1) Display the current adjustment status at point B. (Page 7/7 of process adjustment)

The display for checking the adjustment status is toggled by pressing the “OK” button on the remote control.

(Normal OSD display 

→ “B” → display for check (OSD disappears) → “B” → normal OSD display → ...)

2) Read the value of the luminance meter.

3) Change Point B ADJ R/Point B ADJ B (Adjustment offset value) on page 7/7 of process adjustment so that the values of the luminance meter

approach x = 0.272 and y = 0.277.

(Basically, Point B ADJ G is not changed.)

4) Follow Point A as well as item 3).

Change Point A ADJ R/Point A ADJ B (Adjustment offset value) on page 7/7 of process adjustment so that the values of the luminance meter
approach x = 0.272 and y = 0.277.

5) Select “WB WRITE” on page 7/7 in the process, set “YES”, and press the OK key of remote control.

The adjustment value is written. and then shut down the AC power.

* Initial value of RGB of point B: 3500

* Initial value of RGB of point A: based on calculated of each G point

6) [Adjustment value]

* Teaching set send by engineering dept is set as reference
