Hello Gerd,
I have just been informed by Bang & Olufsen that BC6-23 doesnt have "black bar detection".
It means that it cant measure the proper picture to show unless the connected hardware sends a format video signal.
Pin 8 works fine, because i am controlling the DVBT box with my beo4 remote via pin 8.
I guess i am at the end of the line here. But thanks gor you good ideas and input.
