8. Adjustment of white balance
When the LCD panel or LCD control PWB has been replaced, the white balance may get out of spec. If it is too
much out of spec, take this adjustment.
(1) Preparations
1) Have a white balance measuring instrument [Minolta CA-210] at hand. Place a luminance meter at the
center of the screen.
2) Turn on the TV power and get the set in the following conditions.
AV mode: [DYNAMIC], Monochrome: [ON], Black: [OFF]
The signal is not particularly specified.
(2) Adjustment procedure
1) Enter the adjustment process mode, referring to "3. Entering and exiting the adjustment process mode."
2) Using the cursor (UP/DOWN) keys, select Adjustment Process Pages 10/12/ and 11/12.
3) Using the program (
ù
/
Ù
) keys, move the cursor to MGAMMA R/G/B.
4) Set the cursor to MGAMMA G6 to have the specified gradation "448" at Point 6. The luminance meter
shows the x and y status values. Using the cursor (LEFT/RIGHT) and VOL (+/–) keys, obtain the standard
values of Point 6: x = 0.272 and y = 0.277. Now jot down the G adjustment value of Point 6 ("A"). Do the
same for MGAMMA R6 and MGAMMA B6.
5) Move the cursor to Point 1 (MGAMMA R1/G1/B1) to have the specified gradation "96" at Point 1.
The G initial value "B1" of Point 1 is displayed. Make the following calculation.
(G initial value "B1" of Point 1) x [(G adjustment value "A" of Point 6) / (Gradation "96" of Point 1)] = C1
Adjust the keys so that the C1 value becomes the G setting of Point 1.
For the R and B values of Point 1, adjust the MGAMMA R1 and B1 values, respectively, to the Point 1
standard ones.
