Frequently Asked Questions - 55UM7100PTA LG
How do I set up the TV for the first time?
Connect the TV to power and turn it on. Follow the on-screen setup wizard to select language, connect to Wi-Fi, and scan for channels. If you have a set-top box, connect via HDMI.
How do I connect to the internet?
Go to the Settings menu, select Network, then Wi-Fi Connection. Choose your network and enter the password. You can also use an Ethernet cable for a wired connection via the LAN port.
Why is my remote not working?
First, check if the batteries are installed correctly and have charge. Remove any obstacles between the remote and TV. If still not working, try pairing the remote: press and hold the Back and Home buttons simultaneously for 5 seconds.
How do I install apps?
Press the Home button on your remote, then navigate to the LG Content Store. Browse or search for apps like Netflix, YouTube, and Amazon Prime. Select an app and click Install. Once installed, it appears on the home screen.
Can I mirror my phone screen?

How do I adjust picture settings?
Press the Settings button on the remote, then go to Picture. You can choose picture modes like Standard, Vivid, Cinema, or adjust brightness, contrast, color, and sharpness manually.
Why is there no sound from the TV?
Check if the volume is muted or turned down low. Ensure the audio output is set to TV Speaker in Settings > Sound. If using external speakers, verify the cable connection and that the speakers are powered on.
