I have a DirecTV remote, and it was what i used to control the TV. But since it was reset its not formatted with that anymore, and the only manual control is the power button which cant control anything unlike the samsung sony button that moves left right up and down.
It sounds like you reset your DirecTV remote, not your TV.
Use DirecTV's remote setup site to reprogram your remote to work with your TV again.
