Does it stay on when you do get it to work? How are the after market wires connected? Good clean crimps? They are many variables here, you just need to narrow it down. Like what is the make of the car? Is there a CD still in the player sitting there, not able to remove it but just enough to stop the unit from playing anything. What about the radio? Same problem?
Who installed it? Can you take it back to them for a rework? Fill in the blanks, more than likely if you remove the unit set it down turn the car on, then wiggle the wires ones at a time. See if this helps you out, also use a flash light to look into the CD slot see if there is something in there.
