What people are saying

Rated 5 out of 5 by from Beautiful Picture and Sound I’ve had this tv for 4.5 years and it has a beautiful quality picture and sound. It worked perfectly until last week when the WiFi board failed. I had the extended warranty and the Geek Squad repaired it in 10 minutes. I’ve been very happy with it and would buy again.

Rated 3 out of 5 by from Wireless Features Are Non-Functional It works OK as a television, but wireless features like screen mirroring and wireless internet access will not turn on. The feature is listed, there is a place in the menu for it, but there is not button visible to turn it on.

Rated 4 out of 5 by from 43” LG UJ6300 TV This TV was purchased July 2018 and was our main TV until recently. We recently decided to stream TV rather than using cable for viewing and found the WIFI components were defective. This TV was no longer under warranty and we were not aware of this defect. Amazingly LG provided a repair service at their cost that makes this TV fully operational now for streaming. We are very happy. The TV itself is nit the picture quality of our new 55” LG OLEG TV but is perfect for our bedroom use. Thank you LG!

the sound is not good...does anyone recommend a sound bar and if so ... which one? This TV does not have bluetooth and we have it wired directly to the router so we are limited in which sound bar would work. Please give me suggestions.

Asked by: BarbAgar
The LG 4K UHD HDR Smart LED TV - 43'' Class (42.5'' Diag), Model # 43UJ6300 also has Wi-Fi® Built-In so it can also be connected wirelessly to your router. It has an Optical Digital Audio Out in the back that can be connected to any Soundbar that has an Optical Digital Audio In and the distance from the TV that you can have the Soundbar will depend on the length of the optical cable you use. Some Soundbars will come with an Optical cable although it may not be longer than 3 feet long, and some don't come with one, but you can purchase one from any Consumer Electronics Retailer. Optica cables come in varying lengths...^IFV

Is LG ever going to update the chrome browser to a version which can stop hijacking and pop-ups?

Asked by: Jeremiah777
I am not interested in answers which slide around the question. This web browser is a version years old and has no provision for update. It is virtually unuseable because of the hijack programs - I have found maybe 2 sites that it wont redirect from I would trade the tv in if I could - I believe its a cheaply constructed and difficult to understand and use properly
