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 Digital Box. This is often a result of either the Digital Box being powered off, not being properly connected to the TV, or if the TV is set to the wrong input. 

 

Weak or No Signal

 

The following items are the most common fixes to address the loss of TV signal:

 

Solution 1: Ensuring that the Digital Box is powered on

Solution 2: Check the input on your TV

Solution 3: Pull the power on your Digital Box

Solution 4: Change the cable connection to a different input

Solution 5: No Signal message with audio

 

 

Solution 1: Ensuring that the Digital Box is powered on

CBL Button on Shaw RemotePlease ensure that both the Digital Box and the television are powered on. The method for determining if your Digital Box is powered on will depend on which model you are currently using, but units 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 Digital Box will not power on, please refer to our guide on how to troubleshoot this issue:

Solution 2: Check the input on your TV

In order for your TV to correctly display a picture from the Digital 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, Digital Box) will be connected to a unique input.

 

  1. Power on both your television and the Digital Box. If you find that your Digital 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. Find the remote control that came with your television set and locate the INPUT button. Depending on the brand of your television, this will either be labelled as INPUT, SOURCE, or TV/VIDEO.
  3. Navigate through the list of available inputs on your television by pushing the INPUT button. Each time you press this button, while the input menu appears on your TV screen, the highlighted input name should change. The name of the input you will need to select depends on the type of cable connection you are using to connect the Digital Box to the TV.
      • Coaxial Cable: The input should be set to TV or Cable. The television itself must also be set to channel 03. You will need to change the TV to channel 03 by using the remote that came with your television set or by using the channel up and down buttons that appear on the front of your TV set.
      • HDMI Cable: The input should be set to HDMI1, HDMI2, HDMI3, etc.
      • RCA Cables (Red/White/Yellow): The input should be set to Video1, Video2, Video3 or AV1, AV2, AV3, etc.
      • Component Cables (Red/Green/Blue): Component1, Component2, Component3, etc.

Note

 

If you are using a coaxial cable to connect the Digital Box to your TV and have confirmed that you are on the TV or Cable input and that your TV is currently tuned to channel 03, then you may have to toggle between antenna and cable mode. This can be done by finding and pressing the ANT/CBL button on your TV’s remote.

Solution 3: Pull the power on your Digital Box

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

 

  1. Power off your Digital 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 Digital Box to reboot.
  4. Power on your Digital Box and test it again.

Note

 

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.

Solution 4: Change the cable connection to a different input

If your television has a faulty input it will be unable to read the signal from the Digital Box. Try connecting your Digital Box to a different input port on the back of the television. While connecting the Digital Box to a different input port, take note of the name that accompanies the port you have selected. The port's label indicates which input you will need to select via the INPUT button on your TV's remote.

Solution 5: No Signal message with audio

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 MPEG4 compatible. MPEG4 is a new standard that some HD channels use when broadcasting, and some Shaw Digital Boxes are not able to display the picture on these channels because they lack MPEG4 compatibility. If you attempt to view an MPEG4 channel on a box that is not compatible you will see a blank screen or a screen presenting an error message, but will still be able to hear the channel's audio feed.
