Today, i have bought an "Hdmi to Rca" converter. I have now the "Beosystem3" Dvi out going into a simple "Rca" (yellow cable in a simple scart connection).   SAME PROBLEM!!!!!..... It is surely a setting problem.  I have signal going "On/Off"........ flicking continuously. I am sure it is a "source problem" and i am sure i need to set something in Beosystem options.

I would be very  happy in some help about some can do it.

Hi,

Sorry for the late reply, but I only saw your post recently. I want to come back on the possibility to connect a BV5 screen to a BS3. I had a similar problem several years ago and if I remember correctly, the solution was to select another B&O screen type in the BS3 screen list. You had to select a BV4-50 HD (even if the screen was a 42"). This was one of the (only) screens who sent out the correct IR on/off RS232 commands for the BV5 screen.
If you still have your BV5 screen, you could give it a try. Please don't forget to power off your BV5 screen and BS3 in order to get the changes remembered.

Hope this helps.
