Says "Welcome" starts changing resolutions then turns off. Television is only 1080i and seems like it tries to scan higher then the box is turning off. Was just told of this yesterday, has been this way for about a month as my daughter didn't tell me. I was thinking it may have happened with the 4k HDR update. Any ideas?
