Woot offers a 3rd party plan for purchase on some of their products. Although they have to indicate this option on the product page which I didn’t see on the TV I believe you’re looking at. It would look like this if it was eligible…
The details of this extra warranty can be found here…
Also, some credit cards have a benefit which will double the manufacturer’s warranty. You would have to check if yours has that benefit and the terms you have to follow to qualify. My credit card required a written statement from a repair person, which I had to obtain at my own expense, in order to pay on their coverage but it was still worth it to me.
