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.)

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 set the Chroma-7120 MEM Channel 3 to Warm (6500K) color, MEM Channel 4 to Normal (7300K) color, MEM Channel 9 to Cool (9300K) color , and MEM Channel 10 to sRGB color ( our Warm color parameter is x = 313 ±30, y = 329 ±30, Y>150cd/m2; Normal color parameter is x = 302 ±30, y = 318 ±30, Y>150cd/m2; Cool color parameter is x = 283 ±30, y = 297 ±30, Y>130cd/m2; sRGB color parameter is x = 313 ±30, y = 329 ±30, Y>150cd/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 .

2. Setting the color temp. you want A. MEM.CHANNEL 3 (Warm color):

Warm color temp. parameter is x = 313 ±30, y = 329 ±30, Y>150cd/m2

B. MEM.CHANNEL 4 (Normal color):

Normal color temp. parameter is x = 302 ±30, y = 318 ±30, Y>150cd/m2

C. MEM.CHANNEL 9 (Cool color):

Cool color temp. parameter is x = 283 ±30, y = 297 ±30, Y>130cd/m

D. MEM.CHANNEL 10 (sRGB color):

2

sRGB color temp. parameter is x = 313 ±30, y = 329 ±30, Y>150cd/m2

3. Enter into Factory mode of AOC e1621wb:

Press the MENU button, pull out the power cord, and then plug the power cord. You will enter into factory mode.

4. Bias adjustment:

Set the Contrast to 50; Adjust the Brightness to 80.

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 3 (with up or down arrow on chroma 7120)

3. The LCD-indicator on chroma 7120 will show x = 313 ±30, y = 329 ±30, Y>150cd/m2

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 reachedthe 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±2

49

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 4(with up or down arrow on chroma 7120)

3. The LCD-indicator on chroma 7120 will show x = 302 ±30, y = 318 ±30, Y>150cd/m

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 reachedthe 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±2

C. Adjust Cool (9300K) color-temperature

1. Switch the Chroma-7120 to RGB-Mode (with press “MODE” button)

2. Switch the MEM. Channel to Channel 9 (with up or down arrow on chroma 7120)

3. The LCD-indicator on chroma 7120 will show x = 283 ±30, y = 297 ±30, Y>130cd/m

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

2

7. Repeat above procedure (item 4, 5, 6) until chroma 7120 RGB value meet the tolerance =100±2

D. Adjust sRGB color-temperature

1. Switch the chroma-7120 to RGB-Mode (with press “MODE” button)

2. Switch the MEM.channel to Channel 10 (with up or down arrow on chroma 7120)

3. The LCD-indicator on chroma 7120 will show x = 313 ±30, y = 329 ±30, Y>150cd/m2

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 reachedthe value G=100

6. Adjust the BLUE of 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

E. Turn the Power-button off to quit from factory mode.
