No Signal Message - TV

Note: If you're having trouble with your Internet connection, please visit Troubleshooting Your Wireless Network

Do you see a NO SIGNAL message on your TV? This means that the TV isn't getting an input signal, from the currently selected source! Watch this introduction video about Why No Signal appears on my TV.

Troubleshooting Tips

  • Try switching to each other input, maybe the ports aren't labelled correctly.

  • Try connecting the HDMI cable into a different Input port, maybe the port is malfunctioning.

  • Try connecting a different device to the TV (or the same device to a different TV), maybe the other device is causing the issue.

  • Try using a different HDMI cable, sometimes cables can short-out, or degrade over time.

  • Some devices may have compatibility issues, such as some of the new 4K Blu-ray Players connected to our 4K TVs. It's possible the HDMI HDCP Handshake may be timing out (rare, but it could happen).

  • Visit our community forum's TV - No Signal Discussion thread for more contributions from our users about this issue.

Connection Checklist

  1. Change input source with remote.

    • If your Remote has an Input/Source button input sources, press it and choose the input from the list that matches where your device is connected.

    • If your remote Does Not have an input/source button, press the Home button home button, then look in the Upper-Right corner of the TV for the Input icon input icon, and click it.

    Note: If your Inputs have labels, as shown below, click All Inputs to see the Port numbers.

  2. Pay attention to IN and OUT.

    The cable needs to come OUT of the other device, and IN to the TV. The Input port of the TV will be labelled (HDMI 1, Cable/Antenna, etc.).

    Important: In and Out is an important distinction. A port labelled OUT, will Send a signal, while a port labelled IN will Receive a signal.

  3. Set the TV to the correct source.

    The TV must be tuned to the correct input in order to view the programming of each device.

      A common issue with using an antenna is that they are so easily moved, and may not find the same channels (even in a slightly different position).

      • Run Auto-Tune.

      • If the channel you want to watch isn't found by auto-tune, add the channel manually.

      • Channel Tuning can differ by TV model, but in general:

        1. Go to Settings

        2. Channels

        3. Channel Tuning

      • After adding the channel manually, adjust your antenna until the channel comes in.

      • On some models, you can see the Signal Strength/Quality during Manual Tuning.

      Connecting multiple devices into corresponding input ports must be matched for compatibility.

      Check the label of the Input port.

      Note: If you have multiple devices connected, make sure to follow the wires from the device to the TV to make sure you're looking at the correct input port.
