My $1500 Vizio TV just died 13 months into a 12 month warranty. They don't sell parts for TVs anymore, Vizio support just told me to trash it and buy a new one. Never again Vizio.
Maybe not available through "Them", but "their" prices are usually atrocious.
I've honestly never had a TV just randomly die on me before, which is why I never buy the extended warranties. But Vizio not selling parts for expensive TVs just doesn't sit well with me, hence the "never again".
I still remember when I bought it, I was choosing between it and a TCL. When I asked what the difference was, the guy banged on the back really hard of each. The TCL showed big white splotches when hit, the LG had no effect. He called it 'shielding', but I'm not versed enough to know if that's a thing.
