ADC
Calibrate is used for correcting ADC of VGA and Component channel.
W/B ADJUST is used for adjusting white balance;
POWER MODE is used to set up power-on mode, Standby means the,TV will be in standby state after power-on;
W/B ADJUST is used for adjusting white balance;
POWER MODE is used to set up power-on mode, Standby means the,TV will be in standby state after power-on;
MEM means the TV will be in the same state before the last
power-off.
Force On means the set will be working
automatically after power-on, this mode is also used for factory machine aging. Default setting will
be Standby mode unless you specified.
ISP MODE” is used to upgrade TV software from VGA port when the item is set as ON and the set is connected to ISP adjustment equipment; DDC function of VGA port will be recovered when the item is set as OFF. The value of the item can not be kept in the memory, that is to say the item is reset as OFF after power ON again.

Adjusting
White balance
Default COOL color temperature is 12000K, chromaticity coordinates is 272 ,278 Default Normal color temperature is 9300K, chromaticitycoordinates is 285,293
Default COOL color temperature is 12000K, chromaticity coordinates is 272 ,278 Default Normal color temperature is 9300K, chromaticitycoordinates is 285,293
Default Warm color temperature is 6500K, chromaticity coordinates is 323,329
How to set the white balance
Before adjusting white balance put the TV on for 30 minute.Use white balance apparatus CA-210 and switch to any channel have checked.
1. Switch to HDMI channel.
2. Enter into initial factory menu.
3. Move to item W/B ADJUST and press key Ok to enter into interior factory menu
4. Input DVI/HDMI signal VG-848 Timing: 8561024×768/60 Hz Pattern:921 16 step Gray move cursor to item MODE press keys UP and DOWN to select item HDMI1 or other HDMI channels, then move cursor to item TEMPERTURE press keys UP and DOWN to select item COOL.
5. Adjust items R GAIN,G GAIN,B GAIN to set chromaticity coordinates of the 14th step is 272,278
6. Adjust item R Offset,G Offset,B Offset to set chromaticity coordinates of the 4th step is 272, 278
7. During adjustment,make sure that color temperature of bright step is X=272±10 Y=278±10 and color temperature of dark step is X=272±10 Y=278±10
8. Then move cursor to item COPY ALL to copy white balance data to the other channels except DTV channel
9. Check if color temperature of HDMI NORMAL and WARM meet requirements as below:
Bright step: allowable error is ±10, dark step: allowable error is ±10;
otherwise adjust items R-GAIN ,B-GAIN,R-OFF,B-OFF to meet requirements and then save data.
