Thank you for responding. Software version is 12.5.0 build is 4175-51 model of the Roku express+ is 3910rw I have rebooted it multiple times. I have exchanged hdmi cables. I have tried hdmi ports 1,2 (where it normally goes), and 3. I have unplugged it for 10 minutes, plugged it back in and restarted. It was working perfectly just an hour before the update. After the update the Roku screen is pink, small, and there is no sound. I set it to hdmi and it switches itself to dvi. The television is a TCL. I have video of it changing itself from hdmi to dvi and a photo of the pink screen if that will help.
