Welcome to our Community and thanks so much for your first post; I am sorry that you're getting an error code on your TV services when you contacted us last week. We do have a a dedicated webpage where you can search error codes and go through self diagnostics. You can see that online here
After locating your account I can see that you have contacted us since your post and you were impacted by a known area issue. This area issue has since been resolved. I've run a few checks on your TV services from here and can see that you have rebooted within the last 2 days. We currently have no known area issues that match the issue you have reported.
There are no errors showing from here and all signal levels to the box are where we would expect them to be.
Please do let us know if you're still having issues and we can do further checks with you.
