So I contacted Vizio support and they've been useless. They're not going to change the TV unless I get the entire building's wiring checked and remade, ie, they're not going to do anything if there is no absolutely perfect current flowing to the TV. Asked the guy to be absolutely clear on this, and he made it perfectly clear in simple words.
I'm not certain how things like that works regarding the FCC, but obviously, if they've a FAQ item for it, they probably know their power supply is cheap and poorly filtered. I'm guessing most of you guys have a cleaner power coming to your house (generally in older buildings, all the wires are interconnected with no filtering and its full of RFI. I Believe thats the case here).
So basically, knowing this, I'm just going to buy a power filter and if that doesn't work, I'll return the TV to Amazon, since it would mean it's likely I got a defective model. And that's why I always buy from things like Amazon. Vizio would never take the TV back/exchange it EVEN if it was a defective product, unless you pay people to do all the thorough checks for both TV and full wiring (which would cost half the price of the TV at the minimum in my case, thus does not make any sense - I suppose they know that).
