Rated 5 out of 5 by from This is an excellent quality tv We received this tv as a gift as our old 32" tv died on us. When we set it up, the ease of setting up was amazing. They picture quality was second to none and the features of a smart tv just blew us away. Radio, internet tv, youtube channel, are all so easy to access. For a tv that is not in the high range of dollar value, I would recommend this to anybody!!

Rated 5 out of 5 by from Versatile and great image I was replacing our Plasma that packed it in and I found this unit, that was discontinued at our local depot store. I liked the idea of the LED format and the addition of the SMART function. Although the SMART apps don't seem to include Flixter yet there are a good selection of apps available, and the ability to be on your local LAN is great to share media from your computer. The video and picture quality is very good and the sound is great. I did notice a bit of color change when you are to the extreme right or left of the screen, but you wouldn't be watching from there anyway. Very happy with the unit, so easy to set up.

Rated 5 out of 5 by from 55LB5800 We recently purchased this model LG LED TV. It was easy to set up , gives a picture that rivals a plasma, and colours are bright and true to life. At this point, we are extremely happy with our LG TV. ( This is our second, plasma was our first. )
