What people are saying

Rated 4 out of 5 by from Good tv for the price. Has great picture and features. Im happy with it. Speakers on it are nothing worth mentioning. It does lag out in the menu making it annoying to navigate. Besides that, I would recommend.

Rated 5 out of 5 by from Love it so far. I got this TV 1/15/2016 after my 70" went out. I love it so far. It has a great picture, great internet connection, and great for video games. I saw some saying theirs has went out. I'm guessing some people watch too much tv lol. The tv is light and the sound is great. I would highly recommend smart tvs.

Rated 3 out of 5 by from Disappointed I have had this tv for only 4 yrs and bam its a goner now. I'm disappointed because I still have an earlier version of the flat screens that's probably about 10 yrs old and still works great. I really loved this tv so bummed I gotta go buy a new tv so soon.

Our tv seems to have an issue as every time it's one, the screen is flickering. At first we thought it was the hdmi ports but it seems to do it even with the apps like Netflix. Help?

My tv turns on but nothing happens. No picture and no sound. I have had this tv for a year but just recently installed it about a month ago with no problems. I'm not sure why all of a sudden it's not working?

Asked by: Lovey
The same thing happened to me.  This has to be a defect in the Tv.  Is there a recall on this ?
