Hello sbuss1,
Thanks for posting in Apple Support Communities!
We see that you are getting an error when trying to sign in to the Apple TV app on your Sony TV and you referred to If your Apple ID is locked or disabled, but your account is not saying it is locked.
We’d be happy to help you!
You can make sure that you are not being prompted for a verification code or app specific password through the steps in Sign in with your Apple ID.
It also could be an issue with your network connection.
We’d recommend restarting your TV and making sure the network is connected correctly next.
Take care.
