Learn how to troubleshoot issues if your Shaw TV box will not power on. If you find that your TV box is not powering on please try the following steps to discover the source of the issue and correct the problem. Most commonly, this can be caused by power supply, remote control or TV setting issues. 

Check the power on your TV box

TV won't turn on? Sometimes the fix is easy. Try pulling the power cord out from the back of your TV Box.

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


If you are using a Shaw Gateway, please see the following article:  How to Reset Shaw Gateway 

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. 

Power on the TV box without the remote

Try powering on the TV Box with the physical power button located on the front of the cable box. All of the Shaw TV Boxes have a power button on the front of the unit, with the exceptions of the DCT 700 and Gateway Portal.

If you are able to turn on the TV box using the power button on the front of the unit, or you are currently using a TV box that does not have one of these buttons, this may be an indication that the batteries in your remote control need to be replaced. Try replacing the batteries in your Shaw remote control, and ensuring that they have been inserted correctly.

Check your power outlet/power bar

Another potential solution is to check the power outlet that your cable box is plugged into. (Note: You should always take caution when unplugging devices from wall outlets or power bars.). Use one (or all) of the following tips to troubleshoot when your TV won't turn on. 

  1. Check the power outlet you have your TV box plugged into and ensure that the breaker has not flipped, thus cutting the supply of power.
    • If you find that the breaker has flipped, simply locate your breaker box and turn the corresponding breaker to the on position. Then try to power on your cable box.
  2. Try other nearby outlets to see if you are able to power on the TV box while plugged into an alternative power supply.
  3. If you are using a power bar you can try temporarily bypassing it and plugging your TV box directly into a power outlet on the wall.

The CBL (Cable) button on your remote


Some Shaw remote controls have mode buttons at the top (CBL, TV, VCR, AUX, AUD, DVD) which allow you to control different types of hardware which have been programmed with the remote, thereby allowing you to power them on independently.

Press the Power Button again to turn on your Shaw TV Box. (Note: The CBL button should light up when pressed to indicate the remote has working batteries)

Reprogram your remote

Another reason why your TV Box may not power on using the remote is that your remote may have become deprogrammed. The following example illustrates instructions for how to reprogram the Atlas remote. If you are not sure which remote you currently have please see our overview of Shaw's remote controls

Atlas Remote

  1. Press the CBL button on the Remote
  2. Press and hold the Setup button until the CBL button flashes twice in a row
  3. Enter 1376, CBL should flash twice
  4. Press Power on the remote to test it

Dynamic light sensor interference

Some TVs have automatic sensors for adjusting contrast and brightness of the TV. These sensors can sometimes cause a conflict with the IR sensors in the Shaw remote. To see if your TV's light sensors are interfering with your remote:

  1. Power off the TV
  2. Attempt to power on your TV Box with the Shaw Remote Control while the TV is powered off. If successful, this would indicate that your TV may have an ambient sensor installed that is interfering with the remote.

Use the remote control that came with your television set to find and disable the feature. Depending on your brand of TV, this may be labelled differently. Common labels are Light Sensor, Brightness Sensor, ECO mode, Back Light. See your TV's Owner's Manual or the manufacturer's website for more details.
