Hi Tonin

Regard your fifth option:
"5) If your TV haven't RCA video, BNC video, SCART or RF input, it seems that you haven't a TV, it must be a microwave owen or something like it ...."

Actually, there are TVs without any of those connectors. I guess there are some old TVs with just rabbit ear antennas. I have an LCD TV, Casio TV-1800 with no video inputs other than a built in antenna. I also have a device (called a "Rabbit") that converts an RCA output to broadcast video so I could send Yamaha PSR-9000 signals for viewing on the Casio. However, I am interested in any ideas you may have for connecting the PSR-9000 to the microwave.
