Re: menu keeps appearing on the screen every couple minutes
What does the menu SAY? This might be a menu for a demonstration mode that can be enabled for demo units in a store.
Roku TVs (not other Roku devices) have a store/demo mode that can be selected during initial set up. There is no provision in the user interface to change this later. To get out of store mode you do a factory reset (Settings > System > Advanced system settings > Factory reset) and set up again from scratch. When asked, select home use instead of store/demo.
