First of all apology if there is already owner thread for the yamaha 671 but i searched and searched the forum but couldn't one to help with the issues am having setting up my yamaha 671. This is why I thought it would be a good idea to start this thread for owners of the 671 to share experiences, problems and so on. First of many problems am having is that at the moment I have my sky+ hd connected to hdmi 1 and optical from sky box to av 1 on the yamaha. When in hdmi 1 i get picture but when I switch to av I get dolby digital display on the display pannel but I don't get no picture. Can some one help me with this .
