2-2. Calibration Adjustment of A/D Converter and Video Coder
2-2-1. Preparation for adjustment
1. Set [RGB MODE] of the Custom Setup menu in the service mode to [Other]. 2. Set the [Cal Mode] of the AD Converter in the service mode to [ON].
2-2-3. Component input adjustment
1. Input All white 90 IRE signal of 1080/60i to the component input terminal. 2. Select YUV Calibration from the AD Converter menu. 3. Adjust the Sub Contrast (YUV) and then, adjust the detection values of G to the set value. Detection set value: 230 ± 3 4. Set the component input signal to All gray 20 IRE signal of 1080/60i . 5. Adjust the Sub Bright (YUV) and then, adjust the detection values of G to the set value. Detection set value: 51 ± 3 6. Adjust the CB Offset (YUV) and then, adjust so that the detection value of B is the same as G value. 7. Adjust the CR Offset (YUV) and then, adjust so that the detection value of R is the same as G value. 8. Repeat step 5 to 7 until the detection set value in step 5 above is obtained. 9. Repeat step 3 to 8 until the detection set value in steps 3 and 5 above are obtained.
2-2-2. RGB input adjustment
1. Input All white 90 IRE signal of VGA (640x480/60Hz) to the RGB input terminal. 2. Select RGB Calibration from the AD Converter menu then, Adjust the R and B gain in the menu and balance so that the detection values of R and B is approximate to the detection value of G. 3. Adjust the Sub Contrast (RGB) and then, adjust the detection values of R, G, and B to the set value. Detection set value: 230 ± 3 4. Set the RGB input signal to All gray 20 IRE signal of VGA (640x480/ 60Hz). 5. Adjust the RGB Bias and then, adjust the detection values of R, G, and B to the set value. Detection set value: 51 ± 3 6. Repeat step 1 to 5 described above until the detection set value is obtained.
