9. White-Balance, Luminance adjustment
Approximately 30 minutes should be allowed for warm up before proceeding white
balance adjustment.
Before started adjust white balance, please setting the Chroma-7120 MEM. channel 1 to
6500 color, MEM. channel 2 to 7800 color ( our 6500 parameter is x = 313 ±10, y = 329
±10, Y = 200 ±10 cd/m2 , 7200 parameter is x = 296 ±10, y = 311 ±10, Y = 200 ±10 cd/m2)
How to setting MEM.channel you can reference to chroma 7120 user guide or simple use
“ SC” key and “ NEXT” key to modify xyY value and use “ID” key to modify the TEXT
description
Following is the procedure to do white-balance adjust
Press MENU button during 2 seconds along with press Power button will activate the
factory mode, then MCU will do AUTO LEVEL automatically. Meanwhile press MENU the
OSD screen will locate at left top of panel.
I. Bias adjustment:
to 70.
1.
Set the contrast
2.
Sdjust the Brightness
to 90.
II.
Gain adjustment:
Move cursor to “-Factory-” and press MENU key
a. Adjust 6500 color-temperature
1 Switch the chroma-7120 to RGB-mode (with press “MODE” button)
2 Switch the MEM. Channel to Channel 01 (with up or down arrow on chroma
7120)
3 The LCD-indicator on chroma 7120 will show x = 313 ±10, y = 329 ±10, Y =
200 ±5 cd/m2
4 Adjust the RED on OSD window until chroma 7120 indicator reached the value
R=100
5 Adjust the GREEN on OSD, until chroma 7120 indicator reached G=100
6 Adjust the BLUE on OSD, until chroma 7120 indicator reached B=100
7 Repeat above procedure (item 5,6,7) until chroma 7120 RGB value meet the
tolerance =100±2
8 Press Exit on OSD window to save the adjustment result
33
EN7220 Service Manual
b. Adjust 7800 color-temperature
9 Switch the chroma-7120 to RGB-mode (with press “MODE” button)
10 Switch the MEM.channel to Channel 02 (with up or down arrow on chroma
7120)
11 The LCD-indicator on chroma 7120 will show x = 296 ±10, y = 311 ±10,
Y = 200 ±5 cd/m2
