SOURCE: JBL MR-4 CD doesn't eject
The unit probably doesn't think there is a CD inside. Possible doing a soft reset will fix this. Do so by powering the unit and putting a ball point or other pointed object into the reset button opening either on the face of the radio or behind the face. A hard reset can be done by disconnecting constant power from the unit for approximately 15 seconds.
If either of these methods fail, then your unit has a bad CD mechanism or more than 1 CD inside the player. In that case, the unit will have to be serviced by an electronics repair or a local stereo shop. This is a Marine radio, and if installed on a boat, this problem is not too uncommon. Moist air can cause damage to the unit as well as the bouncing on the water that boats do.
