The controller can't control the TV volume when you are using the Cable mode. If you are using the cable mode it only controls the volume on the cable box so if you want to raise the volume on your TV you have to change the mode to TV. This is inconvenient to have to keep changing the mode back & forth while your watching cable & want to change your TV volume. Also I didn't see a code listing for the Coby brand of TV.
