Somebody I know got this set, which is supposed to be brand new, never used, by helping somebody move. (The other choice was 75 bucks.) He now has a replacement remote and it comes on ok but no channels. What antenna should he get and are there headphones for him to be able to listen without bothering anyone else? I guess it has everything else, the base and instruction manual. Would wifi help? He was supposed to get it but apparently Larry the cable guy never showed.
