We bought a Visio smart tv from Sam’s Club, brought it home, set it up, turned it on...and it lasted about 10 minutes before locking up. The remote did nothing, neither did the minimal manual controls on the set itself. The only way to turn it off was to unplug it.
Took it back and swapped out for a new one. Same thing happened except didn’t even get 10 minutes.
Took it back, got another one. The exasperated salesman said I probably needed to set something differently in our house router (file sharing something or other. I did that. Lasted for about a half hour this time. Locked up again.
Took the Visio Smart TV back, swapped out for a Samsung Stupid TV...works just fine.
Truth is it sounds like yout smart tv was downloading updates.. or was it not hooked to the internet yet?... and/or bad ground on your AC outlet
There is a fix for the VISIO.
Unplug TV,Press TV OFF button for 30 seconds,remove batteries from Remote,Press every button on remote.Put everything back together and everything should work..
