What people are saying

Rated 3 out of 5 by from Great picture I bought this hoping we would no longer need a separate device like a stick to get access our streaming services. Well all was good at first the picture is great, the sound is just ok but there isn’t a tv that has good sound anymore, the setup was fairly easy and had no complaints for the first year. After the first year We started having issues with the network staying connected. This is the only device in our home that we have this issue with. The network connection was never a problem but now it rarely stays connected. We have made sure all firmware is updated, the router has been reset more times than I can count and yet this device still has issue staying connected. After some research it seems this is a common problem with webos offered through LG. Outside this issue We have no complaints about the tv. But I will probably replace it in the near future.

The power button located on the bottom of the TV also doubles as a menu button that can be used to turn the power off, change the input source, scroll through the saved channels and adjust the volume level.
