In my '02 accord coupe EX the radio all of a sudden stopped working. The cigarette lighter still works so it can't be the fuse, and the cassette still spins when the car is on. I can also eject an insert a cassette which is the only way the screen lights up, but there is nothing on the display. the buttons light up when the headlights are on, but none of them seem to do anything except the cassette eject button. Any thoughts on how to fix this?
