Connecting an antenna or cable TV (no box)

  1. Make sure that your TV’s power adapter is unplugged and all connected equipment is turned off.
  2. Connect a coaxial cable (not provided) to the ANT / CABLE IN jack on the back of your TV and to the antenna or cable TV wall jack.
  3. Plug your TV’s power adapter into a power outlet, then turn on your TV.
  4. Press INPUT to open the INPUT SOURCE list.
  5. Press or ▼ to highlight TV, then press ENTER.
  6. If you cannot tune to channels you know exist, scan for channels. See Automatically scanning for channels.
  • Use a coaxial cable to eliminate interference and noise from radio waves.
  • Do not bundle the coaxial cable with the power adapter or other cables.
  • If the antenna is not installed correctly, contact qualified service personnel to correct the problem.
  • If the signal level for a channel is weak, the picture may be distorted. Adjust the antenna or use a highly directional outdoor or set-top antenna with a built-in amplifier.
  • If the picture quality is good on some channels and poor on others, the problem may be caused by a poor or weak signal from the broadcaster or cable TV provider.
  • If you connect to cable TV without a set-top box and experience poor picture quality, you may need to install a set-top box to improve signal reception and picture quality. Contact your cable TV provider about upgrading to a set-top box.
  • Many high-definition (HD) channels upscale standard-definition (SD) content. The picture displayed on your TV is still displayed as SD, thus the picture quality will not be as clear or crisp as it would be if the content was originally recorded in HD.
