Quick Answer: How to troubleshoot no signal issues on your TV
Your TV is not working and you are not able to access any channels or the Guide. You've checked to ensure that your TV and cable box were both plugged in and you have ensured that both your digital box and television are turned on.
Use your Shaw Remote and press the POWER button. Depending on which remote you are using, you may have to press the CBL button on the top of the remote and then the POWER button.
One of the quickest ways to troubleshoot power issues with your equipment is to pull the power and power cycle your equipment. Check your user manual(s) to ensure that this is a preferred practice on your specific television.
