I'm very sorry to hear that has happened. If you could, please let me know how the two devices are currently connected. Also, you said the 3D will turn off. What is your notification of that? Is it just that suddenly you see a double image instead of 3D?
Watching a digital copy of a 3D movie through the Sony Bluray player (waiting for my digital optical cord to show up) and every 20 minutes or so, the tv will turn off the 3D and I will see the usual double picture. Just wondering if this is a compatibility issue, as I don't seem to get this problem when playing straight through the television.
