I am also having the same problem. I went to work with it working fine. Then when i went to lunch it would not boot. Just the white lights come on for about 5 sec then shut off. I pulled it out and confirmed the ground, power, and ACC or still working properly and the fuse in the back of the radio is not blown. I don't know what to do with it either but is out of warranty now and have no clue why it's behaving this way
