Important Safety Notice
Proper service and repair is important to the safe, reliable operation of all AOC Company Equipment. The service
procedures recommended by AOC and described in this service manual are effective methods of performing service
operations. Some of these service operations require the use of tools specially designed for the purpose. The

CAUTION-Use of controls or adjustments or performance of procedures other than those specified herein may
result in hazardous radiation exposure.
CAUTION -The use of optical instruments with this product will increase eye hazard.
TO ENSURE THE CONTINUED RELIABILITY OF THIS PRODUCT, USE ONLY ORIGINAL MANUFACTURER'S
REPLACEMENT PARTS, WHICH ARE LISTED WITH THEIR PART NUMBERS IN THE PARTS LIST SECTION OF
THIS SERVICE MANUAL.
Take care during handling the LCD module with backlight unit
-Must mount the module using mounting holes arranged in four corners.
-Do not press on the panel, edge of the frame strongly or electric shock as this will result in damage to the screen.
-Do not scratch or press on the panel with any sharp objects, such as pencil or pen as this may result in damage to
the panel.
-Protect the module from the ESD as it may damage the electronic circuit (C-MOS).
-Make certain that treatment person’s body is grounded through wristband.
-Do not leave the module in high temperature and in areas of high humidity for a long time.
-Avoid contact with water as it may a short circuit within the module.
-If the surface of panel becomes dirty, please wipe it off with a soft material. (Cleaning with a dirty or rough cloth may

10. White- Balance, Luminance Adjustment
Approximately 30 minutes should be allowed for warm up before proceeding White-Balance adjustment.
1. How to do the Chroma-7120 MEM. Channel setting
A. Reference to chroma 7120 user guide
B. Use “ SC” key and “ NEXT” key to modify x, y, Y value and use “ID” key to modify the
TEXT description Following is the procedure to do white-balance adjust
2. Setting the color temp. you want
A. 6500K color:
6500K color temp. parameter is x = 313 ±20, y = 329 ±20
B. 7300K color:
7300K color temp. parameter is x = 301 ±20, y = 317 ±20
C. 9300K color:
9300K color temp. parameter is x = 283 ±20, y = 297 ±20
D. sRGB color:
sRGB color temp. parameter is x = 313 ±20, y = 329 ±20
3. Enter into factory mode
Press the MENU button, pull out the power cord, then plug the power cord. Then the factory OSD will be at the
left top of the panel.
4. Bias adjustment:
Set the Contrast
to 50; Adjust the Brightness to 90.
5. Gain adjustment:
Move cursor to “-F-” and press MENU key
A. Adjust Warm (6500K) color-temperature
1. Switch the chroma-7120 to RGB-Mode (with press “MODE” button)
2. Switch the MEM.channel to Channel 4(with up or down arrow on chroma 7120)
3. The LCD-indicator on chroma 7120 will show x = 313 ±20, y = 329 ±20
4. Adjust the RED on factory window until chroma 7120 indicator reached the value R=100
5. Adjust the GREEN on factory window until chroma 7120 indicator reached the value G=100
6. Adjust the BLUE on factory window until chroma 7120 indicator reached the value B=100
7. Repeat above procedure (item 4,5,6) until chroma 7120 RGB value meet the tolerance =100±5
B. Adjust Normal (7300K) color-temperature
1. Switch the Chroma-7120 to RGB-Mode (with press “MODE” button)
2. Switch the MEM. Channel to Channel 3 (with up or down arrow on chroma 7120)
3. The LCD-indicator on chroma 7120 will show 7300 color temp. x = 301 ±20, y = 317 ±20
4. Adjust the RED on factory window until chroma 7120 indicator reached the value R=100
5. Adjust the GREEN on factory window until chroma 7120 indicator reached the value G=100
6. Adjust the BLUE on factory window until chroma 7120 indicator reached the value B=100
7. Repeat above procedure (item 4,5,6) until chroma 7120 RGB value meet the tolerance =100±5
C. Adjust Cool (9300K) color-temperature
