Hi @Firefly442
Welcome to our Community Help Forum 🙂
Than you for your post regarding the M63 fault you are experiencing following upgrading to TV360. I am so sorry that this error has occured.
I am glad to hear that you have an engineer appointment booked to get this resolved, apologies for the delay in getting your TV services back up and running. Please do keep us updated with how things go with your engineer appointment.
Thanks,
Serena
