U-verse TV

How do I switch from Samsung tv plus back to ATT uverse

Starting today my Roku TV says I have no Internet connection, but other devices nearby have wireless connection to ATT U-verse

Does not turn on now. Needs replacing.

my guide is zoomed in and also when fast forwarding am unable to read, how can I fix this? I have rebooted several times with no change, the zoom button on the remote has no option to zoom or change. I've checked my TV and it is set where it's supposed to be. My other TV has no problems. Suggestions

I’m trying to link the NBC app to my ATT tv service (u-verse) but I keep receiving an error message that it’s not correct. I then tried to sign in to the u-verse app with my member ID and p/w and I’m receding an error message that it’s not accepted because it’s an att ID. Help!!
