But – there are two issues to consider. The internal tuner in the TV will certainly not work with over the air analogue channels. And may not work with over the air digital channels. (From the antenna)
The mains supply in the UK TV is expecting 240V AC 50hz.
The US Mains is 110V AC 60Hz.. Some modern equiment auto adapts.
I doubt the TV will. A suitable transformer will probably solve this.
