Re-Radio

I have a 91 towncar and replaced the battery and now the radio just shows bar's a cross the front when you turn it on with no sound. It is the compact disc radio I have never had this problem before. All the fuses are good. Do you have to take it in to have some one reset it? THX Bruce

The single din factory radio is known to have capacitor leakage, best to just get an aftermarket one that supports MP3 playback.
