Volume won't work on remote
We got a new box (Version 5 -- we had Version 2). I was able to install it and link the remote, but the volume won't work. The rep who came to our home gave me a new remote but said it was our TV -- "a sensor was out." The TV is only two or three years old. When I returned the old box, the in-store rep said I didn't select the right code for our TV. He gave me a new remote, and I tried to follow the instructions to link this one. The problem: I can't find the screen where you select the TV code. What am I doing wrong?
