REMARK:
1) MCU initialize.
2) Is the EEprom blank?
3) Program the EEprom by default values.
4) Get the PWM value of brightness from EEprom.
5) Is the power key pressed?
6) Clear all global flags.
7) Are the AUTO and SELECT keys pressed?
8) Enter factory mode.
9) Save the power key status into EEprom.
Turn on the LED and set it to green color.
Scalar initialize.
10) In standby mode?
11) Update the lifetime of back light.
12) Check the analog port, are they’re any signals coming?
13) Does the scalar send out an interrupt request?
14) Wake up the scalar.
15) Are there any signals coming from analog port?
16) Display "No connection Check Signal Cable" message. And go into standby mode after the message
disappear.
17) Program the scalar to be able to show the coming mode.
18) Process the OSD display.
19) Read the keyboard. Is the power key pressed?

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 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. 9300k color:
9300 color temp. parameter is x = 283 ±15, y = 297 ±15, Y> 160 cd/m
B. sRGB color:
sRGB color temp. parameter is x = 313±15, y = 329 ±15, Y>170 cd/m
C. 6500K color:
6500K color temp. parameter is x = 313±15, y = 329 ±15, Y>200 cd/m2)

)
3. Into factory mode of HP LE1851w
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
Adjust the Brightness
to 80
to 90.
5. Gain adjustment :
Move cursor to “-F-” and press MENU key
A. Adjust 9300k color-temperature
1. Switch the Chroma-7120 to 9300k channel.
2. The chroma 7120 will show x = 283±15, y = 298 ±15, Y>190 cd/m
3. Switch the chroma-720 to RGB MODE (with press “MODE” button to change )
4. Adjust the RED of color 9300K on factory window until chroma 7120 indicator reached
2
the value R=100
5. Adjust the GREEN of color 9300K on factory window until chroma 7120 indicator reached
the value G=100
6. Adjust the BLUE of color 9300K 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
37
