Same in Cranbrook. There are outages in Vernon and Fairmont. If you can, google shaw outages for updates.
Check that the coaxial-cable between the wall-outlet (or splitter) and your TV box is tightly connected at both ends.
If there is a coaxial-splitter, temporarily bypass it -- connect your TV box directly to the wall-outlet.
Did you "reset" by disconnecting the power-cord from your TV box, and waiting a few seconds, before reconnecting it?
