People! Problem with the cmu ... I've been with a black screen for several days. I have tried rebooting with mute + nav + back and nothing, disconnected the battery and nothing, I have checked the audio fuses 1 and 2 and they are fine. The back connections are fine. I can raise and low the volume, the rest of the buttons do not respond. Burn it?

Thanks!
