The No Signal, No Source or No Input message will appear on your television screen when the television is not receiving a signal from your TV Box. This is often a result of either the TV Box being powered off, not being properly connected to the TV or if the TV is set to the wrong input. See some of the fixes below to troubleshoot weak or no signal on your TV.

Ensure the TV box is powered on

Please ensure that both the TV box and the television are powered on. No signal might just mean that the cable box isn't powered - the cable box will either display a power light or the current channel when powered on. To ensure that your box is powered on, please:

  1. Use your Shaw Remote and press the POWER button. Depending on which remote you are using, you may have to press the CBL button at the top of the remote first and then the POWER button.
  2. If your Cable Box will not power on, please refer to our guide on how to troubleshoot this issue:
     Cable Box will not Power On

In some cases, if you are not receiving a signal on your TV, it could be a result of a service outage. While we try to keep planned outages to a minimum, there are times when services outages may prevent you from accessing your TV services.

Check your input on your TV

In order for your TV to correctly display a picture from the cable box, it will need to be on the correct input. Each device you have connected to your TV (e.g., DVD Player, Blu-Ray Player, Cable Box) will be connected to a unique input. For troubleshooting having no signal on your TV:

  1. Power on both your television and the cable box. If you find that your cable box powers on while the television powers off, or vice versa, press the POWER button that is directly on your television set so that they are both on at the same time.
  2. Using the remote that came with your TV, or a physical button on the TV, press the INPUT button.
    • Depending on the brand of your television, this will either be labelled as INPUTSOURCE, or TV/VIDEO.
  3. Navigate through the list of inputs on your television by pushing the INPUT button. The name of the input you will need to select depends on your connection (HDMI, RCA, or Component cables). While checking connections it's never a bad idea to try to reseat your TV cable connection.
    • If using coaxial cables to the TV you will need to be on the "TV" or "Cable" input and set to channel 3.
    • You may also have to toggle between antenna and cable mode by pressing the ANT/CBL button on your TV’s remote.

Pull the power on your cable box

If you are experiencing technical issues with your TV such as not having a signal, try pulling the power of your PVR or cable box.

  1. Power off your cable box.
  2. Remove the power cable from the back of the unit and unplug the power from the wall or power bar.
  3. Wait 30 seconds and then reconnect the black power cable. It will take between 30 seconds and 2 minutes for the cable box to reboot.
  4. Power on your cable box and test it again.

Your guide listing may read: "To Be Announced" for up to one hour after the power reboot. The guide information will automatically re-populate over time.                 

Change the cable input

If your television has a faulty input it will be unable to read the signal from the Cable Box. For troubleshooting a weak signal on your TV:

  1. Try connecting your cable box to a different input port on the back of the television.
  2. Change the input port selected on your TV via the INPUT button on your TV's remote.

Audio without a picture

If you are able to hear the audio on certain channels but cannot see the picture it may be because you are trying to view an MPEG4 channel through a box that is not compatible, see our Guide to MPEG4 Channels and Digital Cable Boxes.
