I’m setting up my Sony receiver and couldn’t find a remote code listed to operate my Cisco Explorer 8640HDC set top box. By trial and error I found codes 816 and 817 operate the channel up and down but nothing else.
I replaced my Pioneer VSX 816 A/V Receiver with a Sony STR-DN1030. I think the Pioneer was going bad with popping and static coming through the speakers. The new Sony performs beautifully with clear sound. The surround sound is better too. Setup and manual are confusing but the sound quality makes up for that.
