Does Anyone Have A T.V. That You Can Program To Turn Off At A Specific Time, Like 10 P.M. Every Night? What Brand Is It?

You probably want a 'Smart TV'. At the very least you could integrate it with a Google Home and do whatever schedule you want.

maybe you can plug your power supply in a timer. but I'm not sure if its safe to turn a TV on and off this way.

All tv’s have that program you just need to go into the settings it’s in there

Almost all that have been doing this for at least 30 years

Samsung's do it... Look for sleep timer
