I would like to operate my Sony Vizio with my DirecTV remote I want to go into the settings area of my TV is it possible because I want to put it online as well and I don't have a remote other than my DirecTV remote
The DTV remote only provides limited access to the original TV remote functions. They assume you only need to control the power and volume.
If the TV has a phone app to operate it that will work for you.
If the TV has enough buttons on it then you can access the menus that way.
If not then you will need a replacement remote or universal remote like the Logitech Harmony that will provide all the functions of the factory remote.
