Bests & Worsts Reviews from Amazon

After I carefully hooked up this TV, it worked perfectly for about an hour and did everything I wanted - cable TV, Roku, and Hulu. After about an hour the screen suddenly went completely blooey (that is the technical term for a lot of vertical lines over the screen and an unwatchable picture.) I went over all the connections and double and triple-checked them. They were all fine and as should be. I finally hooked up my previous TV and everything is fine and I have to return this TV. Thank heavens for Amazon Prime. I don't know what you call the thing that replaces the picture tube in these new TVs but I guess this one failed completely after about an hour. I won't waste time on another one of these so this one is going back for a refund.
