Android Smart Box – how do I?

The box is a Vigica C90S running Android 4.4.2. This is a combo streaming/FTA (DTV) box. There is a main menu that displays 4 icons; DTV, Kodi, Apps, and Settings. However, on bootup, a few seconds after that menu appears it goes dark and DTV starts up automatically. Is there a way to stop DTV from auto starting? I would prefer the box boot to, and stay on, the main menu.
