Hello, I am new to the Home theater universe and I encountered my first big issue. Here is my "setup": - TV: KDL-50W656A = Sony : Specification for KDL-50W656A | KDL-50W656A technical specifications - A/V Receiver: STR-DG820 = http://www.avforums.com/attachments/strdg820-jpg.126229/ - PS4 Connections: - from PS4 HDMI to A/V Receiver BD In HDMI - from TV Optical out to A/V Receiver TV 'Optical In' - From A/V Receiver HDMI 'Out' to TV My problem: - the optical cable from the TV has issues remaining in the optical A/V socket. It is not a stable "in" position, and the signal is lost at the slightest touch. My questions: - can this be an issue of the actual cable? Has anyone heard of similar issues? - A/V receiver optical socket issue? Has anyone heard of similar issues? - what steps should be made to fix the issue? - replace the Optical Cable with a new one? But what if it's the AV socket issue? I will have 1 extra optical cable (so that would make 2 of them that I have no use for) - buy a component audio cable and use it to output the sound from the TV to the A/V receiver? This would be the 'safest' options in my opinion, but I would hear your advice first. Any other suggestions are welcome, and thank you for your time.
