I am having the exact same problem. I have a TCL tv with built in Roku. Half the time when I am watching a Channel and then try to go back to the Home Screen all the icons on the Home Screen are gone. I have to restart the Roku and then they work fine again. It has happened after watching Sling, YouTube, and Outside tv, so it doesn’t seem to be a channel specific problem. This has only been happening for about the last 3 weeks. I have had the Tv for 3 years
