Nav screen not working 04 mcs

[Rated_R]

I have a 04 Mini Cooper S. The factory navigation screen will not power on. The power light is on on the dvd unit under the passenger seat. I can remove the dvd from the unit and reinsert it. The drive does "spin up" and make other noises that a dvd/cd drive usually makes. But the screen never powers on. Its not a back light issue as there is absolutely nothing on the screen at all in any light.

I tried some of the solutions in some of the other threads on here. Burning different disks in special modes. Still nothing works. The screen unit and dvd unit both appear fine. Neither of them smell like mold or burned electronics.

Anyone have any ideas for me? Like I said. 04 Mini Cooper S manuf 12/2003.
