Colour adjustment procedure
The following adjustments should only be carried out when the CRT or IC801 are replaced.
Notes:
1. This adjustment must be done after warming up the unit for 30 minutes or longer with a beam current over 700 µA.
2. The red value «DRI-RS» should be fixed to 42. (Refer to "How to access service mode" section).
3. «DRI-GS» adjustment alters "Y" coordinate.
4. «DRI-BS» adjustment alters "X" and "Y" coordinates.
Adjustment method 1 (using the signal generator, varying the picture signal)
1. Adjust G2.
2. Input a white pattern with burst signal from SCART.
3. Position the colorimeter in the centre of screen.
4. Adjusting input signal level, select a luminance of 70 nits.
5. Operate again in "service mode" and select «DRI-GS» and/or «DRI-BS» locations to obtain colour coordinates:
X=0.290 ± 0.015
6. Reset the TV with the mains switch button to store the adjustment and exit service mode.
7. Check colour coordinates "X" and "Y" at 20 a 120 Nits. It may be necessary to repeat the same procedure to
obtain the above values.
Adjustment method 2 (using the signal generator, with a fixed picture signal)
1. Adjust G2.
2. Tune a white pattern with burst signal.
3. Operate in "service mode":
4. Using «SUB-CON», select a luminance of 70 nits.
5. Operate again in "service mode" and select «DRI-GS» and/or «DRI-BS» locations to obtain colour coordinates:
X=0.290 ± 0.015
6. Select «SUB-CON». Return data to "63".
7. Reset the TV with the mains switch button to store the adjustment and exit service mode.
8. Check colour coordinates "X" and "Y" at 20 a 120 Nits. It may be necessary to repeat the same procedure to
obtain the above values.
Y=0.300 ± 0.015
Screen Temperature: 8550º K+1 MPCD
Y=0.300 ± 0.015
Screen Temperature: 8550º K+1 MPCD
