Here I am again...

Rare situation: I have nav, tv... etc. I get from the tv module two connectors, for video, and the mono audio.

The issue is that the AV channel only works with my laptop, when I connect the resler usb too.

I also tested the connection with two photo cameras. One... no signal, the other, only works if I touch the cables (but not the connectors, just the shield).


Any explanation?

Thanks and regards,
Manu.
