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]. 3. Set the image quality mode to AV professional standard state.
2-2-3. Component AD adjustment
1. Input All white 90 IRE signal of 1080/60i to the component input terminal. 2. Adjust the Sub Contrast (YUV), that is, adjust the detection value of G to the set value. Detection set value: 230 ± 3 3. Set the component input signal to All gray 20 IRE signal of 1080/60i . 4. Adjust the Sub Bright (YUV), that is, adjust the detection value of G to the set value. Detection set value: 51 ± 3 5. Adjust the CB Offset (YUV), that is, adjust so that the detection value of B is the same as that of G. 6. Adjust the CR Offset (YUV), that is, adjust so that the detection value of R is the same as that of G. 7. Repeat steps 4 to 6 until the detection set value in step 4 is obtained. 8. Repeat steps 2 to 7 until the detection set value in steps 2 and 4 are obtained.
2-2-2. RGB AD 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 gain and the B gain in the menu and balance so that the detection values of R and B approximate to the detection value of G. 3. Adjust the Sub Contrast (RGB), that is, 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, that is, adjust the detection values of R, G, and B to the set value. Detection set value: 51 ± 3 6. Repeat steps 1 to 5 described above until the detection set value is obtained.
