The first one of the 58" I bought did not work, was very disappointed, but since I own two other Visio's I wasn't going to let that be a deterrent, so I returned the t.v. for another of the same model and it works just fine. Nice clear picture, have only had it for about a week, but so far so good.
I have owned numerous Vizio TV's without ever having a problem. After purchasing another brand that died after 2 years, I went back to Vizio. Screen is great, I love that I can cast to the TV -- especially using Apple Airplay. The only disappointment I have and single reason I gave 3 stars instead of 5 is the lack of ability to control what displays on the main screen. You can't remove apps or customize what shows on the main screen. Very disappointing!
