What people are saying

Rated 5 out of 5 by from Good TV at a good price I've had this for about 3-4 years and have had no issues with it. I'm about to replace it as my main TV with another unit. I will certainly consider an LG for a replacement.

Rated 1 out of 5 by from LEDs went out in 3 years So disappointed in this TV we have had it for ONLY 3 YEARS and the LED strips went out so we have a flickering picture audio is fine. This is the worst electronic purchase I have ever made. I refuse to spend any more money on LG or to get this junk fixed.

Rated 5 out of 5 by from Great simple LED TV I've had mine over 4 years now and not a glitch. I run an A/V system, Roku, Dish Network, Digital Antenna, CromeCast, and BlueRay. I wish it had 4K but for 1080P it's a great TV.
