How to activate y pb pr on Beovision 7 Mk I

Hi

I have been trying to connect apple tv 3 to my Beovision 7 Mk I with no luck. I have tried Hdmi / Dvi adapter but the picture is always blinking. I bought adapter to convert hdmi to component RGB ( Y Pb Pr) and audio, the audio works but I can not find the Y Pb Pr in the settings menu on my tv.

So my question is : How can I activate Y Pb Pr input on my Beovision 7 in AV-4 ? I can only choose between NONE and PC

I would appreciate all other ideas.

Y Pb Pr is not available in all AV menus. At my BV 7 Mk 6 it can only be assigned to AV2 and AV3. I don't know which AV you can use with Mk1.

Hope this helps.
