Rated 4.7 out of 5 by 265 reviewers.
Rated 5 out of 5 by A great TV for a great price If you are not worried about having a smart TV or 3D tech, then this is the TV for you. The picture quality is great, and it looks awesome running in 120hz. I have had mine for over a year now, and it has run with zero issues. May 1, 2014
Rated 4 out of 5 by Good Value for 42IN LCD TV After research, we decided to purchase this model at nearby Costco ($650 CAD). The menu interface is easy to navigate, and the unit has functioned without issue since purchase (2+ yrs). I've very satisfied with this product. July 9, 2013
Rated 5 out of 5 by Excellent TV This TV is great. The picture is amazing and it is very easy to use. My only complaint (and it is minor) is I wish there was a way to lock the stand from pivoting. My kids find it fun to push the TV back and forth. August 22, 2012
Rated 5 out of 5 GREAT TV!! Have had alot of tv's in the past but nothing like this one!! So far this has been a GREAT TV!! August 17, 2012
Rated 5 out of 5 by Still Satisfied After 10 Months Use We waited until our cathode ray tube TV died before buying an HD flat panel TV. Our most recent TV had a decent run (only 7 years), but not great. (We've had some TVs last for a couple decades.) We like to use things as long as they still work; we're not ones to buy something when we have a serviceable enough product already. So our desire for getting our money's worth with a quality, reliable product is high. We decided on this model (42LK520) after our research, and have been pleased so far. Great picture, great options for adjusting color, screen size and ratio, de-blur and anti-judder settings, and a number of other features. Has an RF connector, USB port, HDMI ports, A/V cable ports --- everything we wanted. Great sound, so there was no need to buy a sound system. Sturdy, too --- one of our toddlers likes to try and "play" with the TV, and the TV has held up. Very happy with this television. Hope it lasts at least as long as the old TV, if not longer. Time will tell. July 3, 2012
Rated 5 out of 5 by Can not believe how good the picture is!! This is my first HD TV and I could not be more happy with it. June 28, 2012
Rated 5 out of 5 by Oh Yea! We did a lot of research, looked at many brands and models before settling on this one. The best choice on the market if your looking for something with decent size and quality. June 25, 2012
Rated 5 out of 5 by This television has been remarkble! I resisted getting a large screen TV for some time-sticking with my ancient flat screen television. A friend encouraged me to go to hhgregg. I was truly amazed at all of the large screen telelvisions. A customer standing next to me loved his LG. I eventually bought an LG 42' LCD television. It is in hi-def and the picture quality is amazing. I am so glad I bought this product and look forward to watching it every night! June 9, 2012

If you want high definition for your HD content, games and Blu-ray entertainment, there's nothing better than 1080p Full HD. And if you want sports and fast action to be as a crisp as they are exciting, TruMotion 120Hz virtually loses the blur and keeps the sizzle. The LK520 1080p LCD TV brings you both along with the other great features that make LG TVs something better.
