Hey there, marser,
Welcome to our Best Buy forum community! We know that getting a new TV is a big deal, so we are honored that you decided to make this purchase with us. That said, I can understand why you'd be concerned that the TV that you just purchased isn't turning on the next day. I know I'd be anxious to get that sorted out if in your shoes, so I'm glad you came to us for support.
I recommend checking out our Home Theater Troubleshooting Guide, to see if any of those steps help. If you give those a try and the TV still isn't turning on, I'd like to look into next steps, but would need some more info.
Can you elaborate on what happened when you turned on the TV after getting it set-up and mounted, as well as explain more about when you tried to turn it on the next day?
The issue might be that something wasn't connected properly or was loose and got disconnected overnight. Otherwise, if you think that the TV could be defective, I recommend looking at our Return & Exchange Promise, to explore options on that end.
