RGB white balance adjustment
[Condition]
• Make sure the front panel to be used on the final set is fitted.
• Make sure a color signal is not being shown before adjustment.
• Put the color analyzer where there is little color variation.
 [Adjustment]
1. Set COMPONET / RGB-IN SELECT to RGB.
2. Select the IIC mode [PANEL W / B Adj.] item.
3. Check that the color temperature is [COOL (Hi)].
4. Output a white balance pattern.
5. Touch the signal receiver of color analyzer to the highlight window’s center.
6. Fix G drive at E0h and adjust B drive and R drive so x, y become the [Color temperature COOL (Hi)] in the below table.
Adjust it again after it lowers of 08h data when the adjustment is NG. ( In addition, adjust it after it lowers by 08h data for NG. )
7. Adjust R/G/B together by multiplication so the maximum drive value in R/G/B becomes FCh with the gain ratio kept. (ALL-DRIVE)
8. Set color temperature to [NORMAL (Mid)].
9. Fix G drive at E0h and adjust B drive and R drive so the highlight window’s x, y becomes the [Color temperature NORMAL (Mid)] in the below table.
Adjust it again after it lowers of 08h data when the adjustment is NG. ( In addition, adjust it after it lowers by 08h data for NG. )
10. Adjust R/G/B together by multiplication so the maximum drive value in R/G/B becomes FCh with the gain ratio kept. (ALL-DRIVE)
11. Set color temperature to [WARM (Low)].
12. Set G drive to E0h and adjust B drive and R drive so the highlight window’s x, y become the [Color temperature WARM (Low)] shown in the below table.
Adjust it again after it lowers of 08h data when the adjustment is NG.( In addition, adjust it after it lowers by 08h data for NG. )
13. Adjust R/G/B together by multiplication so the maximum drive value in R/G/B becomes FCh with the gain ratio kept. (ALL-DRIVE)
14. Copy the R drive, G drive and B drive data in NTSC, PAL DVI region.
Adjustment target
Hi-light: x ± 0.003 y ± 0.003
Hi-light is target of the number at drive adjustment in the hi-light windows.
Therefore, it is not target of the hi-light number at after adjustment white balance.
YUV white balance adjustment
[condition]
• Make sure the front panel to be used on the final set is fitted.

8. Set color temperature to [NORMAL (Mid)].
9. Fix G drive at E0h and adjust B drive and R drive so the highlight window’s x, y becomes the [Color temperature NORMAL (Mid)] in the below table.
Adjust it again after it lowers of 08h data when the adjustment is NG. ( In addition, adjust it after it lowers by 08h data for NG. )
10. Adjust R/G/B together by multiplication so the maximum drive value in R/G/B becomes FCh with the gain ratio kept. (ALL-DRIVE)
11. Set color temperature to [WARM (Low)].
12. Set G drive to E0h and adjust B drive and R drive so the highlight window’s x, y become the [Color temperature WARM (Low)] shown in the below table.
Adjust it again after it lowers of 08h data when the adjustment is NG.( In addition, adjust it after it lowers by 08h data for NG. )
13. Adjust R/G/B together by multiplication so the maximum drive value in R/G/B becomes FCh with the gain ratio kept. (ALL-DRIVE)
14. Copy the R drive, G drive and B drive data in YUV1_525ip, YUV3_625ip region.
Adjustment target
Hi-light: x ± 0.003 y ± 0.003
Hi-light is target of the number at drive adjustment in the hi-light windows.
Therefore, it is not target of the hi-light number at after adjustment white balance.
Self Check
Display Indication
1. Self-check is used to automatically check the bus line controlled circuit of the Plasma display.
2. There are 2 kinds of Self-check mode Self-check indication and forced to factory shipment setting :
Press the down button on the customer controls at the bottom of the set, at the same time pressing the OFFTIMER button on the remote control, and the screen will show.
Self-check indication only:
Press [5] button on the remote control at ID mode in CAT mode.
If the IIC ports have been checked and found to be incorrect Or not located then [ - -] will appear in place of [OK] [01] in the line of the [PTCT] means the number of blinks of the
Power LED is 1.  [H09] in the line of the [PTCT] is the error code.
To exit the CAT mode switch off the main power
Note: The line of the [PTCT] displays when you get into the Selfcheck mode for the first time only after the Power LED blinks.
LED Blinking timing chart
1. Subject
Information of LED Blinking timing chart.
2. Contents
When an abnormality has occurred to the unit, the protection circuit operates and resets to the stand by mode. At this time, the defective block can be identified by the number of blinks of the Power LED on the front panel of the unit .
