or has this to do with HDCP? Is my BeoSystem compatible with HDCP?

BeoMegaMan's response reminded me that we had 2 TV's respond badly to the last ATV2 update.  One just had to be powered down, but the other had to do a full reset (including account info) to get working.  

Now i have change the cable, reset fully the screen, but still black. Nothing helps. Any more ideas?

Thanks and regards

Did you try another source?

yes, i have tried different sources, but no success.

Are there any other ideas how i can run an ATV2 on my BeoSystem3?

You tried another source, so the ATV2 has nothing to do it. Tried another cable. Different inputs on your BS3. Still no go.

So get your BS3 updated/repaired! I see no other option.

I learned much more than I ever wanted to know about HDMI when I decided to hook up the ATV2 to my Avant.

The problem that you are encountering is a security issue between the ATV2 and the B3. The ATV2 is looking for a security signal from the B3 which is designed to guard copyright protection, and while the lack of the security signal will usually generate audio, the video will then be altered in two common variants: black and white picture or no picture at all. You have proven that the ATV2 is in fact capable of generating the video by connecting it directly to your television.

This leaves you with the following options:

1.    Contact B&O and find out if there is an update for the B3 to support the security signal.

2.    Bypass the B3 and connect directly to the television.

3.    Completely counterintuitive, but: hook up a convertor between the ATV2 and the B3, and feed the B3 through the non-HDMI connection. Below is my post as to what I used to convert the HDMI for use on the Avant:

The Apple TV 2^nd Generation (black) works with the Avant! The solution: feed the HDMI through the LinkStyle HD Video Convertor LK-219414. It gives wonderful color and the sound is perfectly synched. I purchased it from Amazon for $53.99 plus shipping. Have fun and enjoy!

Thank you very much for your answer. I try to find such a converter here in Switzerland do it in the same way as you did. As soon as i have installed such a converter i will report the results.

cheers

This is good stuff Karla.  Did you use an a/b switchbox for the "extra" component cable set? Thanks.

I have not run across a handshake issue with BeoSystem 3, and we have an early series 1 in the store.  If there were a handshake issue, it must have been resolved with software update.  It appears the last time an update addressed HDMI issues was October 2009.

What I haven't done is run to a non-B&O screen.  Is it possible the handshake issue is between BeoSystem 3 and the Pioneer?  We have run Apple TV2 to every recent B&O television with nice results.  

BTW, going to try Roku box next, because it has Hulu+ and many options for on-demand TV.  There goes another HDMI port.
