Adjustment procedures
The TV set should be working above 30 minutes to be in a stabler state before adjustment. Use CA-210 BBY channel to adjust white balance;
* Switch to HDMI channel;
* Press key “INPUT”, then press digital keys “2, 5, 8, 0” in turn to enter into primary factory menu;
* Move cursor to item “W/B ADJUST” and press key “OK” to enter into the inferior submenu;
Input HDMI signal (VG-849 Timing: 856(1024×768/60 Hz)， Pattern:921 16 step Gray); move cursor to item “MODE”, press keys ▲ and ▼ to choose item “HDMI”, then move cursor to item “TEMPERTURE” and press keys ▲ and ▼ to choose “COOL”.
Fix “G GAIN”, adjust “R GAIN, B GAIN” to set 14th chromatic coordinates as (272, 278);
Fix “G OFFSET”, adjust “R OFFSET、 B OFFSET” to set 4th chromatic coordinates as (272, 278).

* To make sure chromatic coordinates of bright scale are (X=272±10， Y=278±10) and chromatic coordinates of dark scale are (X=272±10，Y=278±10) during adjusting;
* Move cursor to item “COPY ALL” to copy white balance data to other channels except DTV channel;
* Check if chromatic coordinates of NORMAL and WARM meet the requirements (permitted error of NORMAL bright scale: x±1,±10, permitted error of NORMAL dark scale: x±10，y±10. permitted error of WARM bright scale and dark scale: x±10,y±10); if not, adjust “R_GAIN /B_GAIN/R_OFF/B_OFF” to be up to the requirements and then save the data.

* Perform “Copy All” for Normal/Warm adjustments except DTV channel.
* Check if chromatic coordinates of other channels meet the requirements, if not, do adjustment for nonstandard channel alone with the same procedures from b) to j) as HDMI channel’s and then save the data.

Switch to HDMI channel, change to 16-grey-scale program from central signal source, adjust white balance with the same procedures from e) to g) as HDMI channel’s; but pay attention not to perform “COPY ALL”
* Inspect all channels after completing adjustment to check if display is normal.
Refer to the following rule for adjustment
