jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
Instrukcja jest OK. Schematy czytelne, opisane niektóre procedury.

2-1-4. AD Adjustment of CVBS Video (NTSC) System
1) Set input to AV1. 2) Input NTSC 50% window Signal 90 IRE in AV1. 3) Set picture quality mode to [PC/GAME]. Send �RGB Level� Command. 4) Adjust Y_OUT_LEVEL until the Green detection value is within a setting value. Detection setting value: 197 ± 3 5) Set Video Signal to NTSC 50% window 20 IRE. 6) Adjust Cb_OFFSET1 until the detection value of Blue becomes same as that of Green. 7) Adjust Cr_OFFSET1 until the detection value of Red becomes same as that of Green. 8) Repeat step 6-7 until it becomes the following detection setting value. Detection setting value: 44 +2 �6 R,G,B detection value dispersion: ± 1 9) Repeat step 2-7 until it is in the detection setting value of 4) and 8). 10) Input NTSC 75% Color Bar signal into AV1. (Fig. 1)

2-1-5. AD Adjustment of CVBS Video (PAL) System
1) Set input to AV1. 2) Input PAL 50% window Signal 90 IRE in AV1. 3) Set picture quality mode to [PC/GAME]. Send �RGB Level� Command. 4) Adjust Y_OUT_LEVEL until the Green detection value is within a setting value. Detection setting value: 197 ± 3 5) Set Video Signal to PAL 50% window 20 IRE. 6) Adjust Cb_OFFSET1 until the detection value of Blue becomes same as that of Green. 7) Adjust Cr_OFFSET1 until the detection value of Red becomes same as that of Green. 8) Repeat step 6-7 until it becomes the following detection setting value. Detection setting value: 44 +2 �6 R,G,B detection value dispersion: ± 1 9) Repeat step 2-7 until it is in the detection setting value of 4) and 8). 10) Input PAL 75% Color Bar signal into AV1.
