Hi all, as the title says. I have a TCL 5 series with roku. After a show ends, the TV switches to that screen where it recommends other shows and the main screen is minimized. If I try to switch back to the main screen to watch the post credits, I get a black screen. Sound works fine. This happens sometimes on YouTube as well after watching an ad. Have no idea what's happening, please let me know if you guys have any clues! Thanks.
