OK, my S590 (about six months old) has started misbehaving, so before I take it out behind the barn, I wanted to check with the collective. It started by doing this thing where sometimes (not always) a movie would start playing just fine, but after about five minutes it'd stop, the player would flash WAIT, and then it would power off. Usually if I powered the player back on and restarted the disc, it'd play all the way through just fine. Now it's gotten worse -- when I load a disc, the tray closes, the player flashes CLOSING for a minute or two after the tray is closed, then spends another couple of minutes flashing LOAD, then sometimes doesn't even recognize that there's a disc in the player. And occasionally it'll randomly shut down in the middle of Netflix or YouTube viewing.
I've turned off deep color and turned off anything to do with TV control over HDMI. I do have a USB flash drive in the back port, but I haven't tried to remove that yet because getting to the back of the player is a bit of a pain. Would that be worth a try? Or is there anything else I can do that doesn't involve a large hammer and/or an S790?
