My head unit won\'t turn on I've got a Kenwood tape deck with a cd changer hooked up to it. On nights I take my top off I detach the face and bring it inside with me. This morning I put the face back in but the unit won't turn on. I checked all the fuses and I know it's getting power because when I take the faceplate off the little red LED flashes on the deck itself (I guess it's a car alarm mimic?) I also made sure the faceplate was snapped in securley. Any suggestions? The deck is about 4 years old but I rarely took the faceplate off up untill this year. I doubt I've even taken it off 25 times in those 4 years.
