Summary: I bought this TV on sale Nov 23, 2012. It was covered by a 1 year warranty. The darn them broke at 13 months! What a crappily manufactured product. The screen goes black, but the sound still works. It happens on cable or DVD.
Summary: I could not have been more disappointed with this TV. Essentially the software, which drives all of the killer features of this TV, are horrible.d On a new TV you have to not only run through multiple updates, but also suffer through horrible user interfaces.
Summary: I'll echo some of the other poor reviews about this tv. I have experienced several intermittent picture problems, ranging from odd shadows to losing the picture completely on occasion. I've been working with LG for the last seven weeks as the unit is still under warranty.
Summary: We purchased this "Smart TV" in November 2012 at HHGregg and within 4 months the picture stopped appearing but audio continued. We called LG and they had local repair person come and replace a board. Same problem reoccurred within a month.
