Did you get error code S0A00?
Next steps
If you have the S0A00 error message it means your TV Box has not yet been activated or has somehow lost its activation. If the error does not go away within approximately one hour, determine if the error message is on all your TVs, or just one, and then contact us so a representative can assist you.
