If possible, take note the each value of the IRIS/OGMTable/Panel driver Gain B on the board before 
replacing.

1.  Change the IRIS data to the values of the IRIS adjustment data before replacement.
 

(For the method to change the IRIS data, refer to “2-4-1. IRIS”.)

 

In case if the data cannot be changed, perform the IRIS adjustment.

 

(For the IRIS adjustment, refer to “2-5. IRIS Adjustment”.)

2.  Obtain the former OGMTable data from the original QA board before replacement as follows.
 

(For the method of obtaining the former OGM Table data from the original QA board before replace-
ment, refer to “2-7-5. Data Obtain Method of the LookUpTable/3DGamma/ABGamma/DDC/OGM-
Table/CSMatrixTable Data from the Board”.)

 

Write down the obtained OGMTable data as follows.

 

(For the method of writing down the obtained OGMTable data, refer to “2-7-4. Data Write Method of 
LookUp Table/3DGamma/ABGamma/DDC/OGMTable/CSMatrixTable”.)

 

In case if the former OGMTable data cannot be obtained from the original QA board before replace-
ment, perform the W/B adjustment.

 

(For the W/B adjustment, refer to “2-3. White Balance Adjustment.)

3.  Return the Panel Driver/Gain B value back to its original value before the QA board is replaced.
 

(For the method of returning the above value to the original value, refer to “2-4-2. Panel Driver Gain 
B”.)

 

In case if the data cannot be changed, perform the Panel Driver Gain B Adjustment.

 

(For the method of Panel Driver Gain B Adjustment, refer to “2-6. Panel Driver Gain B Adjustment”.)

Remove IC200 from the old C board and install it to the new C board before replacement.

No particular adjustments are needed.
