I have a Alpine CDA-7875 http://www.carsound.com/reviews/hd_units/cda-7875.html The other day, my brother ejected a disc and after it spit the disc out, it froze. I couldn't turn it off or anything, it just read "ERROR" on the face. I got home and unplugged it to reset it and it did the same thing. Finally I closed the face gently with my hand (its motorized) and from there I could turn it on and off. So i turned it back on and now it just sits there turning it self on and off, powercyling itself over and over again Is this a common problem? Where can I get it fixed?
