We're sorry to hear that you're not able select TV input. If a particular input can't be selected or greyed out, it means that there is no device connected to port. Are you using an over-the-air antenna or a cable box? Most cable boxes use HDMI input. When using an antenna, an auto program needs to be done to be able to select TV input.
