We needed to disconnect the cable box for moving to a new location. When we tried to rehook it back up (the cable company made the remote for the cable be compatable to this t.v.), we couldn't get channel 3 on the t.v. to get the t.v. working with cable. I pulled out the old remote for this t.v. only to have the batteries get bad inside so that doesn't work. We tried getting the channel three by the nobes on the top. That doens't work. What can we do to get channel 3 on the t.v. so the cable works.
