New Roku Express goes black each time I move on a menu or shows the offers screen
New Roku Express. Hooked up to a Samsung 2020 model smart tv. As soon as I set up the video resolution, each time I move up or down any menu, the screen goes black for a second then comes back on the offers screen. I move again and it goes black again then is back to where I was trying to go (either up or down the menu). I've changed the resolution from 1080 to 720 to auto and the problem persists. I've also rebooted the roku a number of times. It is maddening. It is practically unusable. Any suggestions?
Have you tried switching out the HDMI cable as well as using another HDMI port on the TV to see if you are experiencing the same issue? For troubleshooting purposes, have you tried connecting the device to another TV to see if you are experiencing the same issue?
