re ford 6000cd rds eon car radio?

radio gives no sound except static. I have scaned through both fm and am but it just scans continuesly without picking up anything. the aerial connections are ok and speakers are fine as the cd is working. It just does not stop on a channel like it used to when a signal was received. Im guessing it must be something gone in the pcb where the aerial fits at the back of the radio. Has anyone any ideas before i buy a new radio. Thanks in advance
