Re: there is a store display mode menu that keeps popping up on the screen
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.

If this is a non-RokuTV, then use the TV remote (not a Roku remote) and look under the various settings to enable home mode. Post back your TV model number if you need more help.
If this is a RokuTV, you will have to Factory Reset the RokuTV and select Home Mode during the setup and activation phase. Either press and hold in the Reset button for 30+ seconds or select Factory Reset from the Settings menu,
