Troubleshooting

TV will not turn on

Ensure the power cord is securely plugged into the TV and a working electrical outlet. Check if the remote control has fresh batteries. Try unplugging the TV from the power outlet for 60 seconds, then plug it back in and attempt to power it on.

No picture or sound from connected devices

Verify that the correct HDMI input is selected on the TV. Check that the HDMI cable is securely connected to both the TV and the source device. Try using a different HDMI port or cable. Ensure the source device is powered on and set to output video/audio.

Wi-Fi connection issues

Restart your router and modem. Ensure the TV is within range of your Wi-Fi router. Forget the Wi-Fi network on the TV and try reconnecting, entering the password again. Check for any available firmware updates for the TV.

Apps are not loading or crashing

Ensure your TV has a stable internet connection. Try closing and reopening the app. If the problem persists, uninstall and then reinstall the app. Check for any available software updates for the TV's operating system (webOS).

Picture quality is poor or distorted

Check the TV's picture settings and ensure they are not set to extremes. If watching streamed content, check your internet connection speed. If using external devices, ensure they are outputting a signal matching the TV's capabilities (e.g., 4K resolution).

Cons

  • Some apps and tuner functionality may be region-specific.

Setup, Compatibility & Care

Setup:

To set up your LG NU85 TV, first connect it to a power source. Use the included remote to navigate the on-screen setup wizard. Connect to your home Wi-Fi network or via an Ethernet cable for internet access. You can then sign in to your LG account and configure your preferred streaming apps.

Compatibility:

This TV features three HDMI ports, supporting Audio Return Channel (ARC) and Enhanced Audio Return Channel (eARC), making it compatible with most modern soundbars and AV receivers. Bluetooth 5.3 allows for wireless connection to headphones, speakers, and game controllers. It supports Apple AirPlay 2 for seamless content sharing from Apple devices. The VESA mounting interface (300 x 200 mm) ensures compatibility with a wide range of wall mounts.

Care:

To clean the screen, use a soft, dry microfiber cloth. For stubborn smudges, lightly dampen the cloth with distilled water – never spray liquid directly onto the screen. Avoid using harsh chemicals, abrasive cleaners, or ammonia-based products, as they can damage the screen's coating. Dust the exterior gently with a dry cloth. Ensure the ventilation grills are kept clear of dust and obstructions.
