Sony TV-700U getting audio but no video

[matthewray2b]

I have an adapter running from the EXT ANT port to my Magnavox Odyssey 2. Changing to channel 3 and turning on the Odyssey gives me sound but no video. I can hear the Odyssey beeping from the TV and can hear the game playing but all I get from the video is static. The static pattern changes when I turn on the system but it does not looking like the game. Also, the Odyssey works fine on other TVs. Any ideas?
