Audio Systems: 97 civic stock cd player, civic stock, single cd player

Question
In the 97 civic there is a head unit and a seperate cd player, and when I tried to put the stock one back in. Its saying EEE on the display. Do you know what could be happening or could you tell me how to fixs this problem? Thanks

Answer
the cd player can not read the disc most likely a bad laser
cd player needs to be repair about 85.00 to 140.00 to repair
or you can plug a cd changer 6 disc
or a single cd player with mp3  almost 200 songs per disc
