Frequently Asked Questions - 70UJ6520 LG
How do I connect my LG 70UJ6520 to a soundbar?
You can connect a soundbar using an HDMI cable (ARC) to the HDMI port labeled ARC on the TV. Alternatively, you can use an optical audio cable or Bluetooth if the soundbar supports it. To set the audio output, go to Settings > Sound and select the appropriate output.
How can I update the firmware on my 70UJ6520?
Go to Settings > General > About This TV > Check for Updates. If an update is available, download and install it. Make sure the TV is connected to the internet via Wi-Fi or Ethernet. You can also update via USB using files from LG's official website.
Why does my TV turn off on its own?
Check if the Sleep Timer is set (Settings > General > Timer). Also, if the TV is overheating or if there are power fluctuations, it may shut down. Perform a reset by unplugging the TV for 30 seconds, then plug it back in. If the issue persists, contact LG support.
Can I use the 70UJ6520 as a computer monitor?
Yes, the TV has HDMI inputs that can be used to connect a computer. For best results, set the computer resolution to 3840x2160 and adjust the picture mode to 'Game' or 'PC' to reduce input lag.
What is the wall mount pattern VESA for this model?
The LG 70UJ6520 supports VESA 600x400 mounting holes. Use a compatible wall mount bracket with appropriate screws (M8, length 16-20 mm) to secure the TV safely.
How do I enable HDR on my LG TV?
HDR is automatically supported for compatible content (from Netflix, YouTube, or HDMI devices) if the source is HDR. Ensure the HDMI Ultra HD Deep Color is enabled: Settings > Picture > Additional Settings > HDMI Ultra HD Deep Color, and set the active port to 'On'.
Why is the remote control not responding?
First, check if the batteries need replacing. Point the remote directly at the TV receiver lens within 5 meters. If using the Magic Remote, press the wheel for 2 seconds to pair. You can also download the LG TV Plus app for alternative control.
Can I watch live TV without an external box?
Yes, if you have an antenna/cable connection plugged into the TV's RF input, you can tune channels via Auto Tuning in Live TV. The TV also has a built-in ATSC tuner and can receive digital terrestrial broadcasts.
How do I restart the TV to fix minor issues?
Perform a soft reset by pressing and holding the power button on the remote for 5 seconds until the TV turns off and on again. Alternatively, unplug the TV from the power outlet for 60 seconds, then plug it back in.
Is the 70UJ6520 compatible with voice assistants?
The TV supports LG's ThinQ AI via the Magic Remote. You can use voice commands to control the TV, search for content, and control smart home devices if connected (e.g., Google Assistant or Alexa via external devices).
