I own a newish SONY XBR screen. Recently, it drops the video program and displays a faint message {schedule" : 3351, "created ": 1551876526609, "now" : } looks like programming code. Audio is also lost. The program can be restored by turning the set off and on. Here's the kicker: this event happens every hour on the hour at exactly :48 minutes after the hour. I call Sony customer assistance, they are not helpful. Sounds like software to me, but who knows. Anybody else seen this?
