I bought the TV but a friend started to do it in his email and name how do I delete him
If the TV has been linked to another Roku user, you have to perform a factory reset and set it up on your account as a new device. All existing information on the TV will be wiped, and you will start out as if it just came out of the box.
There's a Settings menu option to perform a factory reset, or you can locate the recessed reset button somewhere on the back of the set and hold it for a minimum of 30 seconds (not one second less) to initiate the reset.
