Sony KW-3200HD with cablebox hd 1080i@50hz

saigo

Hello,

I possess High definition CRT TV Sony KW-3200HD 16/9 (Hi-Vision Muse HDVS) sold only in Japan in 1992.
Problem only 480i@60hz and 1080i@60hz, no 50hz and progressive.

I also possess cable-box HD Sagem HDMI out 1080i@50hz and YUV out only 576i (I live in France)
Thus pay to mitigate these two problems I acquired 2 converters, first (HDCP) HDMI in out YUV or RVBHV and second (Atalona A-HD500) converted 1080i@50hz 1080i@60hz.
In YUV it works but the image is missing.

And in RGBHV (cable VGA towards 5 RCA) I am obliged to connect only a grip of synchro or anybody, because if I connect in more 2 grips of synchro the image is completely blurred with a deaf noise, I have obviously to try to invert Horizontal and vertical synchro but that changes nothing. Thus bizarrely there is an image with only 3 RCA RVB and this image and deformed on the portion of a band on the height of the screen, the connection of RCA synchro in more changes nothing.

Thus I think that it is maybe because out HDMI does not contain a signal RVBHV but a simple signal RVB with the synchro either it is the converter which does not deliver a true signal RVBHV.. But I am anxious to specify that I used these two converters with my monitor Sony (GDM-F520) and the image in HD was completed 1080i@60hz and moreover also there 720p or 1080p there. In YUV it works but the image is missing. It makes as a zoom because of the conversion of the 50hz it 60hz I think.

Thus my questioning are: is there a means to go out of the 60hz directly of the Cable-box HD and in which maybe owed this problem with the exit RVBHV?

Sorry for my bad English.

And thank you in advance for the participants.
