What People Are Saying

Rated 5 out of 5 by from Great price and features Bought this TV on Amazon a week ago to replace our 10 year old Vizio kitchen TV. It’s the perfect size for our kitchen; light and easy to move around; uncomplicated to set up and connect to our Comcast cable; sharp and clear pictures like our new 65 inch OLED family room TV; nice addition to our LG family TVs. Son works in the Silicon Valley’s High tech industry and said ‘great choice’ and loves it to replace our very old tv. It’s a great TV to watch from while eating and bonding with family and friends who visit us. The price is great from Amazon and it shipped quickly. Family lives this new LG addition.

Rated 5 out of 5 by from LG makes long-lasting products Just bought this small LED for a bedroom to replace our last tube/CRT TV. Very easy to set up (automated voice first time set up), and solid image/sound setting features. The sound is a little weak (coming from the back of the TV), but can be adjusted to sound more "full". The only drawback: on this basic model, there are no other connections than ONE HDMI. There is no audio outlet to plug in a soundbar, and you will need to buy an HDMI HUB to connect a DVD player if you already have a cable box plugged in. But for the value and the price, it is understandable. This TV is made for small spaces and basic use. Great quality.

Rated 5 out of 5 by from Great picture and good size The picture looks great. The size allows it to fit into living room rather than requiring the living room to be rearranged around it.

How can i change from hotel mode to a normal antena mode

Asked by: Srgreen4554
In order to change your TV off of hotel mode you would need to take the TV back to where the unit was purchased to have them change the mode or a technician would be needed to change the mode. ^CP
