Not Receiving Digital Channels

[Bonesdad]

Panasonic P46G10. I used to get OTA digital signals on this TV, but I can't seem to get it to find them anymore. I rarely watch OTA tv anymore, but wanted to tune into the Olympics on NBC. I feel like I'm forgetting something obvious, but not sure what it is. My input is set to TV (antenna, not cable) scanned for digital channels and nothing pops up.

Everything else I watch comes through my PS3. Help?

is the antenna connected?

did something PHYSCIALLY happen to the antenna? If it was set up previously, it should not have needed you to rescan for channels, so something obviously changed...
