* About PDP
After done all adjustments, Press IN-START button and
compare Tool option and Area option value with its BOM, if it
is correctly same then Change “RF mode” and then unplug
the AC cable.
If it is not same, then correct it same with BOM and unplug AC
cable.
For correct it to the model’s module from factory JIG model.

9. Adjustment of White Balance
9-1. Purpose and Principle for Adjustment
of the Color Temperature
(1) Purpose: Adjust the color temperature to reduce the
deviation of the module color temperature.
(2) Principle : To adjust the white balance without the
saturation, Fix the one of R/G/B gain to C0 and decrease
the others.

(3) Adjustment mode: Two modes of Cool, Warm and Medium
9-2. Required Equipment
(1) Remote controller for adjustment
(2) Color Analyzer : CA-100+ or CA-210 or same product
(2) Color Analyzer : CA-100+ or CA-210 or same product
- PLASMA TV(ch : 10)
(3) Auto W/B adjustment instrument(only for Auto adjustment)
- Do the white balance adjustment under the 10LUX
* Notice: When using the Color Analyzer with PDP,
recommend the CA-100 more than CA-210.
If CA-100 can not available, it is also good to use the CA-210.
If CA-100 can not available, it is also good to use the CA-210.
