Our VSX-520 has been working for several weeks with no issues, until today. We are no longer getting sound from TV, cable box, tuner or blu-ray.
When attempting to access the setup menu or pushing the buttons on the remote for "auto/direct", "standard", "adv surr", the message "PHONESIN" flashes on the display. After searching through the entire manual (hard copy and online) as well as a thorough search on the internet, I can not figure out what this means.
To the best of our knowledge, no setting have been changed prior to this issue. All connections in and out of the receiver are through HDMI cables. We are currently running a DirecTV cable box and a Samsung BD-6500 Blu-Ray player connected into the receiver and the output is through the Samsung 6300 TV and surround sound with 4 speakers, 1 subwoofer and 2 auxiliary speakers.
