Hi Hebir, welcome to the community! Thank you for posting.
So sorry to hear of this error code issue with your TV service. This is the error code for 'channel missing' so it does correspond with the issue you are having. If ever needed, you can search for TV error codes and get troubleshooting support here: https://virg.in/tverrors.
Would you be able to confirm you have checked all connections are secure, have rebooted the box, but the issue persists?
We will then offer further support! Thank you.
All the best.
