IBM LCD L170 Computer Monitor Service mode
White-Balance, Luminance adjustment
Approximately 30 minutes should be allowed for warm up before proceeding white balance adjustment.
Before started adjust IBM LCD L170 Computer Monitor white balance, please setting the Chroma-7120 MEM. channel 1 to 6500 color, MEM. channel 2 to 7200
color, and MEM. channel 3 to 9300 color ( our 9300 parameter is x = 296 ±10, y = 311 ±10, Y = 190 ±10 cd/m2 and 6500
parameter is x = 313 ±10, y = 329 ±10, Y = 200 ±10 cd/m2 , 7200 parameter is x = 303 ±10, y = 319 ±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 located at left top of panel.
I. Bias adjustment :
1. set the contrast to 90.
2. adjust the Brightness to 100.
II. Gain adjustment IBM LCD L170 Computer Monitor:
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 tolence =100±2
8 Press Exit on OSD window to save the adjustment result
B. Adjust 7200 color-temperature, IBM LCD L170 Computer Monitor
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 = 303 ±10, y = 319 ±10, Y = 200 ±5 cd/m2
12 Adjust the RED on OSD window until chroma 7120 indicator reached the value R=100
13 adjust the GREEN on OSD, until chroma 7120 indicator reached G=100
14 adjust the BLUE on OSD, until chroma 7120 indicator reached B=100
15 repeat above procedure ( item 5,6,7) until chroma 7120 RGB value meet the tolence =100±2
16 Press Exit on OSD window to save the adjustment result
c. adjust 9300 color-temperature
17 Switch the chroma-7120 to RGB-mode (with press “MODE” button )
18 switch the MEM.channel to Channel 03 ( with up or down arrow on chroma 7120 )
19 The lcd-indicator on chroma 7120 will show x = 296 ±10, y = 311 ±10, Y = 190 ±5 cd/m2
20 Adjust the RED on OSD window until chroma 7120 indicator reached the value R=100
21 adjust the GREEN on OSD, until chroma 7120 indicator reached G=100
22 adjust the BLUE on OSD, until chroma 7120 indicator reached B=100
23 repeat above procedure ( item 5,6,7) until chroma 7120 RGB value meet the tolence =100±2
24 Press Exit on OSD window to save the adjustment result
Turn the POWER-button off to on to quit from factory mode.
