D704(SSM12L) Vf=0.38V and If=1A.
So when system power on, the
system loading is about 400mA
(3.3V is about 200mA and 1.8V is
about 200mA), So D35 changed
from 1N4148(or BAT42) to
SSM12L(schottky diode).

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. MEM.CHANNEL 3 (7800 color):

7800 color temp. parameter is x = 296 ±20, y = 311 ±20, Y = 180 cd/m

2 ,

B. MEM.CHANNEL 4 (6500 color):

6500 color temp. parameter is x = 313±20, y = 329 ±20, Y =180 cd/m2

3. Into factory mode of 172V

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:

Set the Contrast

to 50; Adjust the Brightness to 90.

5. Gain adjustment:

Move cursor to “-F-” and press MENU key

A. Adjust C2 (7800) 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 = 296 ±20, y = 311 ±20, Y =180 cd/m

2

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±5

B. Adjust C1 (6500) 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, Y = 180 cd/m

2

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±5

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