Came home late last night and turned on tv online and got the package installer, which I think gave the box an update. Started watching live tv couple minutes later the box shut down. Had to unplug to reset. Then a little later it happen again. Unplugged again and decide not to watch tv. Now today decided to watch live tv and watched for a little while then it shut off again. Remote will not turn it back on and had to unplug again. Is anyone else having this problem?
