All channels including CBC act as if subscription is invalid. Press the remote guide and away you go when you select channel. Then a few seconds or minutes, the same thing happens.
Have you had a chance to disconnect the power to your digital box, and reconnect? Also, is there an error message listed such as "Subscription Service" when the picture disappears, or is it just a blank screen?
If you're noticing the error "One Moment Please," please try the steps available here: https://community.shaw.ca/docs/DOC-1028. If the message states "No Signal," please try these steps: https://community.shaw.ca/docs/DOC-1027. If the message says "Subscription Service," please let me know and I can send you a direct message, so that I can try a reset on the digital box from my side.
