Rated 5 out of 5 by from Perfect for my old lady cave! This set is just what I wanted for my one bedroom apartment. It replaces the 50" I had prior to retirement and features and picture are great.

Rated 4 out of 5 by from smart tv pros:Like color. Sound good. Use without cable hookup to play both vhs and dvd on player hookup and stream movies through wifi. Cons:Streaming not as good video quality as i expected from LG. Not crazy about apps presentation,can't find news channel to stream. Not good instructions on how to use.

Rated 4 out of 5 by from I purchased this TV a month ago and really Like it. I would love it if I were able to figure out how to load additional Apps that are not listed in the LG Store. I had an issue with getting Hulu to load for about 2 weeks and I have very strong Internet Signal. I will add an additional star if someone is able to show me how to Load Ex: CBS all Access and any additional Apps that are not listed in the que. Thank You

Rated 4 out of 5 by from Great picture Only one thing prevents a 5 star rating. Very easy to set up, great picture clarity, easy to access options, BUT, on more than one occasion, when turning the unit on, it turns itself back off immediately. Truly not sure why it does this. It will stay on with the next attempt.

Rated 5 out of 5 by from great picture We're trying to wean ourselves off cable. So far so good. We will probably replace all of the TVs with Smart TVs.
