What broke - normally the TV's have the TYPE F female screw on type connector for the TV ANTENNA INPUT and RCA PHONO type connectors for other inputs.... TV antenna input connector looks similar to this on the back of the TV

Did the chassis connector on the TV itself get pulled out or maybe just the TYPE F MALE connector on the end of TV cable going to the TV SET get pulled off...
If the cable end got pulled off the cable that goes to the TV set this should be will be a easy fix with a new like connector from radio shack. This is a screw on cable plug - no tools required
Need more info what broke...
