Summary: TV is less than a year old and now has some connection issues. However, it's not the TV I dislike, but I would like to write a review about how bad the customer service is at Panasonic. You pretty much get the run around, and no one can help you solve any issues. Go to Samsung.
Summary: The only problem I encountered is it does not have any inputs on the edge of the TV, which is a hassle if you want to connect things after it is mounted on the wall. E.g. memory cards or hdmi devices. if you want to do that, you'd need a bracket that permits you to pull it away from the wall.
Summary: All of my friends comment on how clear my TV is. I haven't had any problems set up was great. Volume could be a little better sometimes to watch a quiet film I need to turn it up 60% volume level.
Summary: Good blacks and color saturation. Good feature set and easy to use. Great for the price. I compared this TV next to my buddy's new 50' Samsung 1080p 120 Hz LED (I forget the Samsung model #, but it was a midrange priced set, just like my Panasonic) and I thought it stood out.
Summary: I love this Panasonic, best LED available, i saw high quality videos of it at the 2013 CES show in vegas and had to have it! Smart TV is cool, works perfect! I advise anyone that can find one to just buy it, make sure you get a soundbar or home theater system if you don't already have one.
Summary: Originally purchased the Vizio (not 3D) and was very disappointed with the picture quality as well as the apps. Paid a bit more for the Panasonic 58 inch and am very happy that i did. Much better picture and the applications are very intuitive and easy to navigate through.
