I just plugged in xg1v4 box tonight after years of no issues with previous x1 box. (Wanted that 4K upgrade). Plugged in and worked perfectly for 2 hours. Then went black. I still have audio if that even makes sense. Did all the changing of cables, changing inputs on tv, rebooting, system refresh, CEC on/off, etc. box has power and I can change channels, as I can hear the tv thru the tv speakers but screen is black. Unplugged xg1v4 box and plugged old box back in (haven’t shipped it back yet) and it works just perfectly. When checking online both boxes when plugged in appear connected. I have a new vizio p-series. I know there are no answers here, but sharing my issue as I will Return this box and probably just keep my old one
