Error messages can appear when you are trying to access On Demand content. The errors can be triggered by issues with signals, cables, service availability, and issues with your account.
If you have more than one TV box in your home, check to see if they are all affected by the same issue. If they are all affected — or you have just one box and no access — contact Technical Support for assistance. If you are able to view channel 999, jot down the number displayed in the bottom right-hand side of your screen and share this number with the support representative, if asked.
