55 inch Onn powered by Vizio TV

TV turns off by itself, sometimes has to be unplugged and replugged to get sound. When TV turns itself off, have to go back and change the input. Had to connect to the internet just to get the thing set up even though it will not be connected to internet to watch.

Volume

I love this tv but 2 weeks in and the volume which we used to have on 30 now has to be on 60....not sure what is going on or if we did something. I am going to try to do some googling to see how to fix.

Amazing Quality & Picture for price

I’d buy 10000 of these tvs if I could, everything about it is great. I love how you can use the app as a remote if it ever gets lost or you can’t find it. The volume is loud even on number 3-4 it’s like having it on 30. Picture quality is amazing and so are the free tv apps.
