13. Check List 1) After replacing LCD Main board and panel, Check if white-balance is within the specs, then
re-writing DDC is necessary. The white-balance value for each common color temperature:
9300 parameter is x=28328, y=29728, Y = 180 10 cd/m2,
6500 parameter is x =31328, y=32928, Y = 180 10 cd/m2,
5700 parameter is x = 328 28, y = 344 28, Y = 180 10 cd/m2)
The color temperature value above must be up to the situation of x

7. Select Exit to the upper menu after completing the adjustment. Then press POWER OFF to exit and save it.
3) 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 for VGA) (Connection for DVI)
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.
3. Input the serial number of the product (For instance: AOC LM725 is 13 bits), and 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, theData compare OK! Means being written well and thats 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 doesnt
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, and then cut the signal cable and the power.
6. The following picture is taking AOC LM725 EDID for example.
