6) Take the same steps as in 5) for the following.

1 Set Point 2 to the specified gradation "136".

Multiply the G initial value "B2" of Point 2 by ["A" / Gradation "136" of Point 2] to have the G setting
C2 of Point 2. Adjust the MGAMMA R2 and B2 values, respectively, to the Point standard ones.

2 Set Point 3 to the specified gradation "248".

Multiply the G initial value "B3" of Point 3 by ["A" / Gradation "248" of Point 3] to have the G setting
C3 of Point 3. Adjust the MGAMMA R3 and B3 values, respectively, to the Point 3 standard ones.

3 Set Point 4 to the specified gradation "324".

Multiply the G initial value "B4" of Point 4 by ["A" / Gradation "324" of Point 4] to have the G setting
C4 of Point 4. Adjust the MGAMMA R4 and B4 values, respectively, to the Point 4 standard ones.

4 Set Point 5 to the specified gradation "396".

Multiply the G initial value "B5" of Point 5 by ["A" / Gradation "396" of Point 5] to have the G setting
C5 of Point 5. Adjust the MGAMMA R5 and B5 values, respectively, to the Point 5 standard ones.

5 Set Point 6 to the specified gradation "448".

Multiply the G initial value "B6" of Point 6 by ["A" / Gradation "448" of Point 6] to have the G setting
C6 of Point 6. Adjust the MGAMMA R6 and B6 values, respectively, to the Point 6 standard ones.

[White balance adjustment standard values]

Point 1 standard values: x = 0.272, y = 0.277 (gradation 96)
Point 2 standard values: x = 0.272, y = 0.277 (gradation 136)
Point 3 standard values: x = 0.272, y = 0.277 (gradation 248)
Point 4 standard values: x = 0.272, y = 0.277 (gradation 324)
Point 5 standard values: x = 0.272, y = 0.277 (gradation 396)
Point 6 standard values: x = 0.272, y = 0.277 (gradation 448)

Factory settings

See to below caution

» Enter the adjustment process mode.
» Bring the cursor on to [INDUSTRY INIT] on page 2/12.
» Using the VOL (+/–) keys, set to [ON]. Press the OK key to execute the

initialization. The /////// pattern appears, and the adjustment process
mode is automatically replaced by the TV screen. Now the initialization is
complete.

` Never turn off the power during the initialization process.

The following settings will be back to their factory ones.

1. User settings

2. Channel data (e.g. broadcast frequencies)

3. Password data

To exit the adjustment process mode, unplug the AC power cord from the outlet to force off the power. (When
the power is turned off with the remote controller, once unplug the AC power cord and plug it in again. In this
case, wait 10 seconds or so before plugging.)

Caution: When the factory settings have been made, all user setting data, including the channel settings, are

initialized. (The adjustments done in the adjustment process mode are not initialized.) Keep this in
mind when initializing these settings.
