Remote control won't change TV channels

Please try these steps to resolve the issue with changing TV channels: 

1. If your remote has a dash (-) button, use it to access digital channels. For example, if the channel you want to access is 6.1, press 6, then the dash button (-), and then 1.
2. If your remote does not have a dash button, you might not be able to use the number buttons to tune directly to a digital channel. Use the channel up and down buttons instead.
3. If this is a new problem for you or you have a new TV:
   1. Make sure there are no obstacles between the remote and your TV.
   2. Move closer to the TV and make sure the remote is pointed directly at the TV's front panel.
   3. Make sure the batteries are installed correctly.
   4. Try fresh batteries.
   5. Finally; if your remote is over four years old, it might not be able to operate some newer TV's, or it may be able to operate only some functions but not others.
