TV not responding to remote

[whatiswrongwithmytv]

My tv is stuck on HDMI 1 saying the device it gone. This is true as I removed cable services. My remote will not work. Tried resetting the remote and tv. Even gave purchase 3 remotes and they will not pair. The button on the tv will allow me to turn it on and move it but cannot select an option. To power off the tv I have to unplug.

Have you tried to run the diagnostics on the tv? Newer tvs will have the device care app to run diagnostics on the tv.

I can’t get access to try to run any testing.

Hello! Thank you for reaching out! I would recommend trying to use the SmartThings remote on your phone if possible to control the TV for now. Please use the following link: https://www.samsung.com/us/support/answer/ANS00078933/.

So we can help further can I also have your full model number to help?
