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 special
tools should be used when and as recommended.
It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully read in
order to minimize the risk of personal injury to service personnel. The possibility exists that improper service methods
may damage the equipment. It is also important to understand that these CAUTIONS and NOTICES ARE NOT
EXHAUSTIVE. AOC could not possibly know, evaluate and advise the service trade of all conceivable ways in which
service might be done or of the possible hazardous consequences of each way. Consequently, AOC has not undertaken
any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recommended by
AOC must first satisfy himself thoroughly that neither his safety nor the safe operation of the equipment will be
jeopardized by the service method selected.
Hereafter throughout this manual, AOC Company will be referred to as AOC.
WARNING
Use of substitute replacement parts, which do not have the same, specified safety characteristics may create shock, fire,
or other hazards.
Under no circumstances should the original design be modified or altered without written permission from AOC. AOC
assumes no liability, express or implied, arising out of any unauthorized modification of design.
Servicer assumes all liability.
FOR PRODUCTS CONTAINING LASER:
DANGER-Invisible laser radiation when open AVOID DIRECT EXPOSURE TO BEAM.
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
damage the panel.)

• Save the original shipping carton and packing materials, as they will come in handy if you ever have to ship your
monitor.
• For maximum protection, repackage your monitor as it was originally packed at the factory.
• To maintain the cleanness of your LCD display, wipe it periodically with clean and soft cloth. The screen may be
damaged by any liquid splash.
• To keep the monitor looking new, periodically clean it with a soft cloth. Stubborn stains may be removed with a
cloth lightly dampened with a mild detergent solution. Never use strong solvents such as thinner, benzene, or
abrasive cleaners, since these will damage the cabinet. As a safety precaution, always unplug the monitor before
cleaning it.

9. 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 xyY 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. MEM.CHANNEL 3 cool (7800K color):
2
7800K color temp. parameter is x = 296 ±20, y = 311 ±20, Y = 180 cd/m
B. MEM.CHANNEL 4 warm (6500K color):
6500K color temp. parameter is x = 313±20, y = 329 ±20, Y =180 cd/m
3. Into factory mode
Turn on power, press the MENU button, pull out the power cord, and then plug the power cord. Then the factory
OSD will be at the left top of the panel.
4. Bias adjustment:
.
2
.
Set the Contrast
to 50; Adjust the Brightness to 80.
5. Gain adjustment:
Move cursor to “-F-” and press MENU key
A. Adjust 7800K 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)
2
3. The LCD-indicator on chroma 7120 will show x = 296 ±20, y = 311 ±20, Y =180 cd/m
4. Adjust the RED of color1 on factory window until chroma 7120 indicator reached the value R=100
5. Adjust the GREEN of color1 on factory window until chroma 7120 indicator reached the value G=100
6. Adjust the BLUE of color1 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±2
B. Adjust 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)
2
3. The LCD-indicator on chroma 7120 will show x = 313 ±20, y = 329 ±20, Y = 180 cd/m
4. Adjust the RED of color3 on factory window until chroma 7120 indicator reached the value R=100
5. Adjust the GREEN of color3 on factory window until chroma 7120 indicator reachedthe value G=100
6. Adjust the BLUE of color3 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±2
Turn the Power-button off to quit from factory mode.
