REMARK:

HP F1905E

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?

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. 9300 color:

9300 color temp. parameter is x = 283 ±20, y = 297 ±20, Y > 180 cd/m

B. 6500K color:

6500K color temp. parameter is x = 313±20, y = 329 ±20, Y>200 cd/m2)

C. SRGB
SRG color temp. parameter is x = 313±20, y = 329 ±20, Y >200 cd/m2)

2 ,

3. Into factory mode of HP F1905E
Turn on power, at the same time press the up (+) key and menu key, 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 80

Adjust the Brightness to 90.

5. Gain adjustment:

Move cursor to “-F-” and press MENU key
A. Adjust 9300 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 = 283 ±10, y = 298 ±10,
Y = 210 ±10 cd/m2

4. Adjust the RED of color1 on factory window untilchroma 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

38

HP F1905E

B. Adjust SGB 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 ±10, y = 329 ±10,
Y = 210 ±10 cd/m2

4. Adjust the RED of color3 on factory window until chroma 7120 indicator reached
the value R=100

5. Adju the GREEN of color3 on factory window until chroma 7120 indicator reached

the 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

C. Press reset key and Turn the Power-button “off to on” to quit from factory mode.

11. Check List After Replacing LCD Main Board

Check if white-balance is within the specs after replacing Main board and panel, then re-writing DDC is necessary.

Ⅰ. Check white -balance

The white-balance value for each common color temperature:

9300K: x=283± 20 ; y = 297±20;

6500K: x = 313± 20 ; y =329±20;

The color temperature value above must be up to the situation of x<y. The value of Y should be confirmed
according to different customers. 15 ”LCD is commonly 180±20cd/cm
larger than 200cd/cm
different customers and different models.

2

(Center). The exact brightness values are confirmed by the checking-regulations of

Ⅱ. Steps of white-balance adjustment for LCD:(Take 19” HP LCD for example)

1. Required instruments: Chroma7120、Chroma2325（BGA265A）。

2. First connect the instruments together and turn on the LCD power, then warm up for 30 minutes under full

2

（Center）and 17” LCD is required to be

white screen mode. First press the “Reset” key in the menu to recover factory set as following.

a) Set Chroma2325 at round-windows mode and make the detecting-head of Chroma7120 aim at the cross in the

middle, the distance between the detecting-head and the cross is 20cm.

b) Set Chroma2325（BGA265A）to be T144（1280*1024/60HZ）and P105 of full white screen. Test if the

white-balance value is within the specs. Please follow the steps below to adjust if it is beyond the specs.

c) Cut the power. Then press Minus (“-“) key and supply power at the same time to enter into the factory mode.

See the following pictures.

40

HP F1905E

d) T est white-balance again after Auto Level. Adjustment with hand is necessary if it is beyond the specs just the

same.

e) Select 7x00 item to adjust cool color-temperature and select 6x00 to adjust warm color- temperature. It can

reach to the best effect through adjusting R/G/B value if it inclines to green or blue.

f) Select Exit to the upper menu after completing the adjustment. Then press POWER OFF to exit and save it.

Ⅲ. Steps for writing DDC：

1. Employ PC, and connect the DDC-writing instrument and the instrument that is ready for writing into DDC
to the power of 12v. Connect the signal cable of the latter to D-USB or DVI of DDC-writing instrument (The
data-writing of monitor needs transfer-interface) and link the DDC-writing instrument with PC through printer
interface. (See the schematic picture below)

Connection of DDC-writing instrument for

2. Seek the document with the expanded name of .BAT in DDC file of this model. It appears the indication of
“Input Serial No.：＂after dual-click the document to be ready for DDC-writing.

41

HP F1905E

3.Input the serial number of the product (For instance: AOC LM729 is 13 bit s), then press ENTER to start writing

4.Check the indication of DDC-writing program at the end. When you see the picture as the schematic picture above,

the “Data compare OK!” means being written well and that’s the end. Please check if the Manufacturer Name,

Vendor Assigned Code, Monitor Name, Serial Number, Week of Manufacture, Year of Manufacture are right. It will

appear “Data compare error ！” to indicate failure if the DDC-writing doesn’t perform well. Please check the

power resource and the connection of the signal cable, then return to step 3 by pressing ENTER and re-do it.
