Rated 3 out of 5 by from TV works great, but... I've had this TV for about a year and it's worked great. However after assembling the legs I noticed it was a bit wobbly and leaned forward slightly. it didn't seem very sturdy. Just recently I observed that the TV was leaning forward at much more pronounced angle. Turns out that one of the legs had cracked. Seems weird since I'm unaware of anytime when extra stress was put on the feet. So now I want to replace the feet with something more robust. I'm purchasing an after market device that will utilize the 4 rear mounting holes. I see from the FAQs that the holes are 6 mm (M6). but I need to know the pitch of the screw threads. Advice: don't rely on the supplied legs to secure the TV, especially if young children are in the home. It needs to be anchored so it can't fall.

Is there any other buttons on the TV other than the power button if so where

Asked by: Cn123
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.

I see that the LG 55UJ6300 does NOT have a bluetooth transmitter for wireless headphones. I saw that older LG televisions say you can use a USB plug in small device (dongle). WHAT BLUETOOTH TRANSMITTER DO WE NEED TO USE WIRELESS HEADPHONES WITH THIS TV?

Asked by: TexasUSAFVet
Hello TexasUSAFVet. Regrettably, the LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ6300 is not compatible with the Wi-Fi® Bluetooth® USB Dongle for Select 2014 LG TVs, MOdel # AN-WF500 which is the last Wi-Fi® Bluetooth® USB Dongle we made that was only compatible with select 2014 LG TVs. That device did not transmit Bluetooth signals. It only received them so that you could use Bluetooth devices that transmit Bluetooth signals with those select TVs. The USB ports on the TV do not support USB Audio so there is no way to use a Wi-Fi® Bluetooth® USB Dongle to transmit audio to Bluetooth headphones...^IFV
