Companion box XiD-C turns off during Welcome screen

[SeraphStrife]

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?

There is no such thing as a 4K update as that box isn’t capable.. You may have to swap it.

My main box DVR updated about a month ago and is running in 4k HDR at 2160p. Apparently this is when that one Companion box stopped working, the other two Companion boxes are working.

I understand that the Companion boxes are not 4k, that's not what I was asking. It goes to the welcome screen and starts checking resolutions, light blinking green then shuts off as if it's losing sync when it tries to scan higher.

I’d still swap it out
