Could be a disconnected wire, bad ground, a break in the wire (inside the insulation). Are they one and the same (a radio with a clock on it)? Could be the component died (bad transistor, diode, faulty soldering, etc).
The antenna must be simply disconnected.. if there is no signal for the station, the radio auto mutes to keep you from hearing static.. so yes.. remove the radio and yourll know what the antenna wire is and what i goes into.
