Facing TV Problems? Ask a TV Technician.
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
What you'll need to do is have the input mode set to tv (not hdmi, etc),
go into the LG menu, under OPTION, then Initial Setup, there you should see the input type where you can choose air/antenna or cable, and run the scan again.
If it still isn't picking anything up, you may need to rotate the antenna slightly a few degrees (experiment both horizontally and vertically)
