What people are saying

Rated 1 out of 5 by from No help at all My 43in TV out of nowhere stopped working, and LG said there was nothing they could do because it was out of warranty. I guess how they like to sell their products, have it work fine for the first few years then once it's no longer under warranty they break leaving you screwed .

Rated 1 out of 5 by from Blue Screen in 15 minutes after turning TV on I bought LG 43UF6430 4K UHD Smart LED TV 2-3 years back. Due to unexpected situation at home, we never open the TV box till today. Today my husband removed the TV from box. After installing the legs and putting it on TV stand, he plugged the power cable in socket. He used remote which came along with box to switched on the TV. TV started. He gone through initial set up. We don't have cable, so he connected TV to WIFI. He clicked on YouTube app where TV prompted him to update the app. He did that. Then he tried to play kids video (Peppa Pig) on YouTube, screen went dark. Nothing is coming up on screen. Whenever TV is turn on, BLUE COLOR is showing on screen. I am feeling really bad that we didn't open this TV when we bought it. We could have noticed this issue right away and could have returned it to retailer. I am fan of LG products; however I really disappointed with TV experience.

Does this model support Hulu? My Hulu onced worked and now it doesn't. I read on Hulu that LG televisions that were manufactured after 2014 would work.

Asked by: Cordcutter
If Hulu does not appear in the content store or if the Hulu application says your TV is no longer supported, we would not be able to provide a workaround to allow the application to work. A list of available applications for the 43UF6430 can be found on the following page: http://us.lgappstv.com ^CP

Is there any way to wirelessly connect additional speakers for surround sound?

Asked by: Kmae
I apologize, but no; certain television models can connect to a wireless sound bar, and through it, other wireless speakers. However, those TVs require a Bluetooth module, which is unavailable on this particular TV.
