Audio Systems: 2002 Chrysler Town & Country CD Changer, chrysler town, country cd

Question
I have a 2002 Chrysler Mini Van with a 4 disk changer. A couple of weeks ago, the car wouldn't start, the positive battery cable had become corroded.  Cleaned it up, charged the battery, and everything was fine except the CD changer.  The LEDs on the front blink, first 1&2 light at the same time, then 3&4, back and forth. Unit is completely locked up.  I have tried leaving the battery disconnected for hours at a time.  Is there a reset button?  Is it in anti-theft mode?  Thank you for your time.

Answer
This is the first time I have heard of this in a chrysler van.
It could be locked due to an anti-theft device, you will have to talk to the dealer about resolving, if so.
There could be a reset button, again the dealer will be the best resource.

Sorry I cannot be of more assistance.
