Does this occur when going to and/or returning from commercials? This is probably caused by the commercials being at a different resolution and/or frame rate than the program you're watching. The Roku/TV combination must reset its video parameters for each such transition and this can cause a short blackout.

My screen goes black after a few minutes but only on the MGM channel. That is the only channel I like to watch on Roku so it is very annoying. When I exit back to the menu and go right back in it starts playing again but after a few minutes it goes black again and will stay that way until I exit out and go back in. Why does this do this. I have restarted a few times and it is not only doing it on one Roku, I have two units connect and it is doing it on both. The Roku Express 3930.
Did you find a solution? Mine is doing the same during shows on any app. When on spectrum app keeps asking if I'm watching, comes on as soon as I turn to a channel, then continues to ask every 1 minute. I have to keep pressing the ok button or it will turn off.
Wow! That is more annoying than the screen going black. It will play for about 4 hours then every 1/2 to 1 hour after that it goes black. I have to back out to the main menu and select the channel again and it comes back on. So annoying. No I haven't have any replies about this yet. As soon as I get a response I will let you know.
I wanted to let you know that I got a reply from Roku. They said to remove the channel from my home screen, reboot the system and then add it back. The problem is the channel I am having issues with is within the Roku channels and I don't have the option to remove it. I am waiting to hear back from them regarding my question whether I should remove the entire Roku icon and then put it back.
