11. Check List After Replacing LCD Main Board SOLD FOR: American
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;
sRGB: 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 17” HP LCD for example)
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 cros s 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.
37
HP VS17E
d) Test 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 sign al cable of the latter to D-USB or DVI of DD C-writing instrument (Th e 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.
38
HP VS17E
3.Input the serial number of the product (For instance: AOC LM729 is 13 bits), 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.
5.You can exit the program by pressing Ctrl plus C, then cut the signal cable and the powe r.
6.The following picture is taking Acer AL1721 EDID for example.
Notes:
1、Make sure the system time of PC is in accordance with the real time before writing.
2、The schematic picture is just as an example for description, the exact content of the DDC is dependent on the
serial number of the BARCORD of this model.
3、Data DDC-writing needs a transfer interface.
39
Instruction:DDC-writing needs 4 files:
1. Barcode.txt (Supply Barcode length and flow number)
2. *.EXE (DDC-writing program)
3. WR.bat (Group order file for cycling utilization of *EXE, and dual-click this file when perform
DDC-writing)
