=> Caution : Before White-balance, the AV ADC should
be done. (ZH:AV3, TH:AV1, MH:VIDEO1)
=> After Aging, When the procedure is changed White
balance adjustment, it will be canceled Heat_run mode
auto.
(Notice : Before White-balance, change input mode Move
to AV3(ZH) or AV1(TH) or VIDEO1(MH) by using
the FRONT-AV KEY on Remote controller.)

adjustment.
- AV ADC(ZH: AV3, TH : AV1, MH: VIDEO1)
should be done before White-balance.

6.1 Manual white Balance (AV)
1) Execute CA-110 Zero Calibration.
2) Execute the SET Heat Run for 30minutes
3) As below Fig. 4, Supply 216Level (85 IRE) full screen
pattern to Video input.
37LC2R-ZH,42LC2R-ZH : AV3/AV4 (Input 50Hz),
32LB1R-TH : AV1/AV2 (Input 50Hz)
4) Press the FRONT-AV KEY on R/C for converting input
mode.
5) Set the PSM to Standard mode in Picture menu.
6) Enter the White Balance adjustment mode by pressing the
INSTART key twice(White Balance) on R/C.
7) Stick sensor to center of the screen and select each items
(Red/Green/Blue Gain and Offset) using /(CH+/-) key
on R/C.
8)Adjust Only High Light with R Gain/B Gain using /(VOL
+/-) key on R/C.
9) Adjust it until color coordination becomes as below.
X-axis : 0.283±0.003
Y-axis : 0.298±0.003
(R/G/B gain and R/G/B offset Default values are different in
according to using module )
10) Adjust High light with R/B Gain.
