Yea im assuming its the deck, a fuse, or the wire at the back of the unit somehow disconnected (illumination wire). Only problem is, im having quite some difficult removing it from my cc lancer. I see the clips at the front of the headunit after removing the face & little front rectangle cover, but cant figure it out. I think theres the bracket that screwed into the car, and the deck then slides into it and clips in. I just got to figure out how to slide it back out, otherwise might undo the bracket, and removing the entire lot. Oh and i dont know the pinout. I've tried in the past to read voltage levels, and i got nothing. We were positive theres a switch somewhere that when the face is put into place, it turns on, and the voltages will come through the pins, but i couldnt find it.
